In an exemplary embodiment, the adjustable bell section expansion cone assembly 28 may be, or may include elements, of one or more conventional adjustable expansion devices for radially expanding and plastically deforming wellbore casing, or equivalents thereof.

An end of an adjustable casing expansion cone assembly 30 is coupled to another end of the adjustable bell section expansion cone assembly 28. In an exemplary embodiment, the adjustable casing expansion cone assembly 30 may be, or may include elements, of one or more conventional adjustable expansion devices for radially expanding and plastically deforming wellbore casing, or equivalents thereof.

An end of a packer control device or packer assembly 36 is coupled to another end of the stinger assembly 34. In an exemplary embodiment, the packer assembly 36 may be, or may include elements, of one or more conventional packers.

In an exemplary embodiment, one or more of the elements of the system 10 may be omitted, at least in part, and/or combined, at least in part, with one or more of the other elements of the system.

As illustrated in FIG. 1, in an exemplary embodiment, during operation of the system 10, an expandable wellbore casing 100 is coupled to and supported by the casing lock assembly 24 of the system. The system 10 is then positioned within a wellbore 102 that traverses a subterranean formation 104 and includes a preexisting wellbore casing 106.

As illustrated in FIG. 2, in an exemplary embodiment, the extension actuator assembly 26 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 downwardly in a direction 108 and out of an end of the expandable wellbore casing 100. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved to a position out of the end of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly and adjustable casing expansion cone assembly are then operated to increase the outside diameters of the expansion cone assemblies. In an exemplary embodiment, the increased outside diameter of the adjustable bell section expansion cone assembly 28 is greater than the increased outside diameter of the adjustable casing expansion cone assembly 30.

As illustrated in FIG. 3, in an exemplary embodiment, the ball gripper assembly 16 is then operated to engage and hold the position of the expandable tubular member 100 stationary relative to the tubular support member 12. The tension actuator assembly 18 is then operated to move the adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, packer assembly 36 upwardly in a direction 110 into and through the end of the expandable wellbore casing 100. As a result, the end of the expandable wellbore casing 100 is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 to form a bell section 112. In an exemplary embodiment, during the operation of the system 10 described above with reference to FIG. 3, the casing lock assembly 24 may or may not be coupled to the expandable wellbore casing 100.

In an exemplary embodiment, the length of the end of the expandable wellbore casing 100 that is radially expanded and plastically deformed by the adjustable bell section expansion cone assembly 28 is limited by the stroke length of the tension actuator assembly 18. In an exemplary embodiment, once the tension actuator assembly 18 completes a stroke, the ball gripper assembly 16 is operated to release the expandable tubular member 100, and the tubular support 12 is moved upwardly to permit the tension actuator assembly to be re-set. In this manner, the length of the bell section 112 can be further extended by continuing to stroke and then re-set the position of the tension actuator assembly 18. Note, that, during the upward movement of the tubular support 12 to re-set the position of the tension actuator assembly 18, the expandable tubular wellbore casing 100 is supported by the expansion surfaces of the adjustable bell section expansion cone assembly 28.

As illustrated in FIG. 4, in an exemplary embodiment, the casing lock assembly 24 is then operated to engage and maintain the position of the expandable wellbore casing 100 stationary relative to the tubular support 12. The adjustable bell section expansion cone assembly 28, adjustable casing expansion cone assembly 30, packer setting tool assembly 32, stinger assembly 34, and packer assembly 36 are displaced downwardly into the bell section 112 in a direction 114 relative to the expandable wellbore casing 100 by operating the extension actuator 26 and/or by displacing the system 10 downwardly in the direction 114 relative to the expandable wellbore casing. After the adjustable bell section expansion cone assembly 28 and adjustable casing expansion cone assembly 30 have been moved downwardly in the direction 114 into the bell section 112 of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly is then operated to decrease the outside diameter of the adjustable bell section expansion cone assembly. In an exemplary embodiment, the decreased outside diameter of the adjustable bell section expansion cone assembly 28 is less than the increased outside diameter of the adjustable casing expansion cone assembly 30. In an exemplary embodiment, during the operation of the system illustrated and described above with reference to FIG. 4, the ball gripper 16 may or may not be operated to engage the expandable wellbore casing 100.

As illustrated in FIG. 5, in an exemplary embodiment, the casing lock assembly 24 is then disengaged from the expandable wellbore casing 100 and fluidic material 116 is then injected into the system 10 through the tubular support 12 to thereby pressurize an annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is created across the cup seal assembly 22 that causes the cup seal assembly to apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing.

In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the injection of the fluidic material 116 to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.

As illustrated in FIG. 6, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the packer assembly 36 is positioned within a portion of the expandable tubular member above the bell section 112. The packer assembly 36 may then be operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112.

In an exemplary embodiment, after the packer assembly 36 is operated to engage the interior surface of the expandable wellbore casing 100 above the bell section 112, a hardenable fluidic sealing material 122 may then be injected into the system 10 through the tubular support 12 and then out of the system through the packer assembly to thereby permit the annulus between the expandable wellbore casing and the wellbore 102 to be filled with the hardenable fluidic sealing material. The hardenable fluidic sealing material 122 may then be allowed to cure to form a fluid tight annulus between the expandable wellbore casing 100 and the wellbore 102, before, during, or after the completion of the radial expansion and plastic deformation of the expandable wellbore casing.

As illustrated in FIG. 7, in an exemplary embodiment, the fluidic material 116 is then re-injected into the system 10 through the tubular support 12 to thereby re-pressurize the annulus 118 defined within the expandable wellbore casing below the cup sub assembly 22. As a result, a pressure differential is once again created across the cup seal assembly 22 that causes the cup seal assembly to once again apply a tensile force in the direction 120 to the system 10. As a result, the system 10 is displaced upwardly in the direction 120 relative to the expandable wellbore casing 100 thereby pulling the adjustable casing expansion cone assembly 30 upwardly in the direction 120 through the expandable wellbore casing thereby radially expanding and plastically deforming the expandable wellbore casing and disengaging the stinger assembly 34 from the packer assembly 36. In an exemplary embodiment, during this operational mode, the packer assembly 36 prevents the flow of fluidic materials out of the expandable wellbore casing 100. As a result, the pressurization of the annulus 118 is rapid and efficient thereby enhancing the operational efficiency of the subsequent radial expansion and plastic deformation of the expandable wellbore casing 100.

In an exemplary embodiment, the tension actuator assembly 16 may also be operated during the re-injection of the fluidic material 116 to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100.

As illustrated in FIG. 8, in an exemplary embodiment, the radial expansion and plastic deformation of the expandable wellbore casing using the adjustable casing expansion cone assembly 30 continues until the adjustable casing expansion cone assembly 30 reaches the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106. At which point, the system 10 may radially expand the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 and the surrounding portion of the preexisting wellbore casing. Consequently, in an exemplary embodiment, during the radial expansion of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106, the tension actuator assembly 16 is also operated to displace the adjustable casing expansion cone assembly 30 upwardly relative to the tubular support 12. As a result, additional expansion forces may be applied to the expandable wellbore casing 100 and the preexisting wellbore casing 106 during the radial expansion of the portion 124 of the expandable wellbore casing that overlaps with the preexisting wellbore casing.

As illustrated in FIG. 9, in an exemplary embodiment, the entire length of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is not radially expanded and plastically deformed. Rather, only part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is radially expanded and plastically deformed. The remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 is then cut away by operating the casing cutter assembly 14.

As illustrated in FIG. 10, the remaining part of the portion 124 of the expandable wellbore casing 100 that overlaps with the preexisting wellbore casing 106 that is cut away by operating the casing cutter assembly 14 is then also carried out of the wellbore 102 using the casing cutter assembly.

Furthermore, in an exemplary embodiment, the inside diameter of the expandable wellbore casing 100 above the bell section 112 is equal to the inside diameter of the portion of the preexisting wellbore casing 106 that does not overlap with the expandable wellbore casing 100. As a result, a wellbore casing is constructed that includes overlapping wellbore casings that together define an internal passage having a constant cross-sectional area.

In an exemplary embodiment, one or more of the operational elements of the system 10 may be omitted, at least in part, and/or combined, at least in part, with one or more of the other operational elements of the system.

In an exemplary embodiment, during operation of the casing cutter assembly 14, the retracting spring 14044 is compressed and thereby applies a biasing spring force in a direction 14092 from the lower tubular mandrel 14006 to the tubular spring housing 14034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 14052 and the upper casing cutter segments 14054 out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, during operation of the casing cutter assembly 14, an external threaded connection 12a of an end of the tubular support member 12 is coupled to the internal threaded connection 14002d of the upper tubular tool joint 14002 and an internal threaded connection 16a of an end of the ball gripper assembly 16 is coupled to the external threaded connection 14068f of the tubular member 14068.

The upper cam assembly 14052 and the upper casing cutter segments 14054 may be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by pressurizing an annulus 14094 defined between the lower tubular mandrel 14006 and the tubular spring housing 14034. In particular, injection of fluidic materials into the cam cutter assembly 14 through the longitudinal passage 14006b of the lower tubular mandrel 14006 and into the radial passage 14006ba may pressurize the annulus 14094 thereby creating sufficient operating pressure to generate a force in a direction 14096 sufficient to overcome the biasing force of the retracting spring 14044. As a result, the spring housing 14034 may be displaced in the direction 14096 relative to the lower tubular mandrel 14006 thereby displacing the tubular upper hinge sleeve 14050, upper cam assembly 14052 , and upper casing cutter segments 14054 in the direction 14096.

In an exemplary embodiment, as illustrated in FIGS. 11P, 11Q and 11R, the displacement of the upper cam assembly 14052 and upper casing cutter segments 14054 in the direction 14096 will cause the lower casing cutter segments 14058 to ride up the cam surfaces of the cam arms of the upper cam assembly 14052 while also pivoting about the lower tubular hinge segment 14064, and will also cause the upper casing cutter segments 14054 to ride up the cam surfaces of the cam arms of the lower cam assembly 14060 while also pivoting about the upper tubular hinge segment 14050.

In an exemplary embodiment, during the operation of the casing cutter assembly 14, when the upper and lower casing cutter segments, 14054 and 14058, brought into axial alignment in a radially expanded position, the casing cutter elements of the casing cutter segments are brought into intimate contact with the interior surface of a pre-selected portion of the expandable wellbore casing 100. The casing cutter assembly 14 may then be rotated to thereby cause the casing cutter elements to cut through the expandable wellbore casing. The portion of the expandable wellbore casing 100 cut away from the remaining portion on the expandable wellbore casing may then be carried out of the wellbore 102 with the cut away portion of the expandable wellbore casing supported by the casing cutter elements.

In an exemplary embodiment, the upper cam assembly 14052 and the upper casing cutter segments 14054 may be moved out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by reducing the operating pressure within the annulus 14094.

In an alternative embodiment, as illustrated in FIGS. 11S, 11T, 11U and 11V, during operation of the casing cutter assembly 14, the upper cam assembly 14052 and the upper casing cutter segments 14054 may also be moved out of engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060 by sensing the operating pressure within the longitudinal passage 14006b of the lower tubular mandrel 14006. In particular, as illustrated in FIG. 11T, if the operating pressure within the longitudinal passage 14006b and radial passage 14006bb of the lower tubular mandrel 14006 exceeds a predetermined value, the burst disc 14086 will open the passage 14084a thereby pressurizing the interior of the tubular release sleeve 14088 thereby displacing the tubular release sleeve 14088 downwardly in a direction 14092 away from engagement with the locking dogs 14080.

As a result, as illustrated in FIG. 11U, the locking dogs 14080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 14006 thereby permitting the lower casing cutter segments 14058 and the lower cam assembly 14060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 11V, the operating pressure within the lower tubular mandrel 14066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 14094 relative to the tubular lower mandrel 14006 and the retracting piston 14074. As a result, the lower tubular mandrel 14066, the lower casing cutter segments 14058, the lower cam assembly 14060, and tubular lower hinge sleeve 14064 are displaced downwardly in the direction 14094 relative to the tubular spring housing 14034 thereby moving the lower casing cutter segments 14058 and the lower cam assembly 14060 out of engagement with the upper cam assembly 14052 and the upper casing cutter segments 14054.

In an exemplary embodiment, as illustrated in FIGS. 11W, 11X, and 11Y, during operation of the casing cutter assembly 14, the casing cutter assembly 14 senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 14022 and 14028, lower toggle links, 14024 and 14030, and triggers, 14026 and 14032, and then prevents the engagement of the upper cam assembly 14052 and the upper casing cutter segments 14054 with the lower casing cutter segments 14058 and the lower cam assembly 14060.

In particular, as illustrated in FIG. 11W, anytime the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 14026 and 14032, will be pivoted by the engagement arms, 14024d and 14030d, of the lower toggle links, 14024 and 14030, to a position in which the triggers will no longer engage the internal flange 14034d of the end of the tubular spring housing 14034 thereby permitting the displacement of the tubular spring housing in the direction 14096. As a result, the upper cam assembly 14052 and the upper casing cutter segments 14054 can be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, the upper toggle links, 14022 and 14028, and the lower toggle links, 14024 and 14030, are spring biased towards the position illustrated in FIG. 11W.

Conversely, as illustrated in FIG. 11X, anytime the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 14026 and 14032, will be maintained in a position in which the triggers will engage the internal flange 14034d of the end of the tubular spring housing 14034 thereby preventing the displacement of the tubular spring housing in the direction 14096. As a result, the upper cam assembly 14052 and the upper casing cutter segments 14054 cannot be brought into engagement with the lower casing cutter segments 14058 and the lower cam assembly 14060. In an exemplary embodiment, the triggers, 14026 and 14032, are spring biased towards the position illustrated in FIG. 11X.

In an exemplary embodiment, as illustrated in FIG. 11Y, the tubular spring housing 14034 may be displaced upwardly in the direction 14098 even if the upper toggle links, 14022 and 14028, and lower toggle links, 14024 and 14030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, as illustrated in FIGS. 11Z1 to 11Z4, 11AA1 to 11AA4, 11AB1 to 11AB4, 11AC1 to 11AC4, 11AD, and 11AE, the tubular spring housing 14034 of the casing cutter assembly 14 defines internal annular recesses 14034k and 140341, spaced apart by an internal flange 14034m, the tubular toggle bushing 14008 defines an external annular recess 14008ac, and the casing cutter assembly further includes pins, 14100a and 14100b and 14102a and 14102b, mounted in holes 14008j and 14008o and 14008k and 14008n, respectively, of the tubular toggle bushing, and a one-shot deactivation device 14104 mounted on the tubular toggle bushing between the pins, 14100a and 14100b and 14102a and 14102b.

The one-shot deactivation device 14104 includes a tubular body 14104a that defines radial holes, 14104b and 14014c, and includes an external annular recess 14104d at one end, a centrally positioned external flange 14104e, a centrally positioned internal annular recess 14104f, and an external annular recess 14104g at another end. An engagement member 14106 that includes a base member 14106a having a tapered end 14106b and a key member 14106c having a tapered end 14106d is received within a portion of the internal annular recess 14104f of the tubular body 14104a and an engagement member 14108 that includes a base member 14108a having a tapered end 14108b and a key member 14108c having a tapered end 14108d is received within an opposite portion of the internal annular recess 14104f of the tubular body 14104a. Spring members, 14110 and 14112, are received within the annular recess 14104f of the tubular body 14104a for biasing the base members, base member 14106a and 14108a, of the engagement members, 14106 and 14108, respectively, radially inwardly relative to the tubular body 14104a.

In an exemplary embodiment, during operation of the casing cutter assembly 14, as illustrated in FIGS. 11Z1 to 11Z4, the one-shot deactivation device 14104 are positioned proximate and in intimate contact with the pins, 14102a and 14102b, with the tapered ends, 14106b and 14108b, of the base members, 14106a and 14108a, of the engagement members, 14106 and 14108, received within the external annular recess 14008ac of the tubular toggle bushing 14008. When the one-shot deactivation device 14104 is positioned as illustrated in FIG. 11Z, the external annular recess 14104d of the tubular body 14104a of the one-shot deactivation device is moved out of engagement with the engagement arms, 14026d and 14032d, of the triggers, 14026 and 14032, respectively. As a result, the triggers, 14026 and 14032, may operate normally as described above with reference to FIGS. 11W, 11X, and 11Y.

Conversely, in an exemplary embodiment, during operation of the casing cutter assembly 14, as illustrated in FIGS. 11AA1 to 11AA4, the one-shot deactivation device 14104 are positioned proximate and in intimate contact with the pins, 14100a and 14100b, with the tapered ends, 14106b and 14108b, of the base members, 14106a and 14108a, of the engagement members, 14106 and 14108, not received within the external annular recess 14008ac of the tubular toggle bushing 14008. When the one-shot deactivation device 14104 is positioned as illustrated in FIGS. 11AA1 to 11AA4, the external annular recess 14104d of the tubular body 14104a of the one-shot deactivation device is moved into engagement with the engagement arms, 14026d and 14032d, of the triggers, 14026 and 14032, respectively. As a result, the triggers, 14026 and 14032, are deactivated and may not operate normally as described above with reference to FIGS. 11W, 11X, and 11Y.

In an alternative embodiment, the elements of the casing cutter assembly 14 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted or adjusted to sense any pre-selected internal diameter of the expandable wellbore casing.

In an exemplary embodiment, as illustrated in FIGS. 12A1 to 12A4, 12B and 12C1 to 12C4, the ball gripper assembly 16 includes an upper mandrel 1602 that defines a longitudinal passage 1602a and a radial passage 1602b and includes an internal threaded connection 1602c at one end, an external flange 1602d at an intermediate portion that includes an external annular recess 1602e having a shoulder 1602f and an external radial hole 1602g, an external annular recess 1602h, an external annular recess 1602i, an external annular recess 1602j having a tapered end 1602k including an external annular recess 1602ka, an external annular recess 16021, and an external annular recess 1602m, and an external annular recess 1602n, an external radial hole 1602o, an external annular recess 1602p, and an external annular recess 1602q at another end.

One or more inner engagement elements 1618a of a tubular coglet 1618 engage and are received within the external annular recess 1602ka of the tapered end 1602k of the external annular recess 1602j of the upper mandrel 1602 and one or more outer engagement elements 1618b of the coglet engage and are received within the internal annular recess 1608d of the deactivation tubular sleeve 1608.

An external annular recess 1620a of an end of a tubular coglet prop 1620 that includes an inner flange 1620b receives and mates with the inner surfaces of the outer engagement elements 1618b of the coglet 1618.

An end of a tubular activation sleeve 1630 that defines a plurality of radial openings 1630a, a radial opening 1630b, a radial opening 1630c, and includes an internal annular recess 1630d receives and mates with the tubular ball race 1628. In an exemplary embodiment, an end face of an end of the tubular activation sleeve 1630 is positioned proximate and in opposing relation to an end face of an end of the deactivation sleeve 1608. In an exemplary embodiment, the radial openings 1630a are aligned with and positioned in opposing relation to corresponding of tapered annular recesses 1628a of the tubular ball race 1628, and the radial openings are also narrowed in cross section in the radial direction for reasons to be described.

Balls 1632 are received within each of the of tapered annular recesses 1628a and corresponding radial openings 1630a of the tubular ball race 1628 and tubular activation sleeve 1630, respectively. In an exemplary embodiment, the narrowed cross sections of the radial openings 1630a of the tubular activation sleeve 1630 will permit the balls 1632 to be displaced outwardly in the radial direction until at least a portion of the balls extends beyond the outer perimeter of the tubular activation sleeve to thereby permit engagement of the balls with an outer structure such as, for example, a wellbore casing.

A lower mandrel 1634 that defines a longitudinal passage 1634a and an internally threaded radial passage 1634b at one end and includes internal annular recesses, 1634c and 1634d, for receiving and mating with the external annular recesses, 1602p and 1602q, of the upper mandrel 1602, an internal annular recess 1634e, an external flange 1634f, and an externally threaded connection 1634g at another end. In an exemplary embodiment, as illustrated in FIG. 12B, the end of the lower mandrel 1634 further includes longitudinal recesses 1634h for receiving and mating with corresponding axial engagement elements 1628d of the tubular ball race 1628. A sealing element 1635 is received within the internal annular recess 1634d of the lower mandrel 1634 for sealing an interface between the lower mandrel and the external annular recess 1602p of the upper mandrel 1602.

A tubular spring retainer 1636 that defines a radial passage 1636a and includes an external annular recess 1636b at one end mates with and receives the end of the lower mandrel 1634 and is positioned proximate an end face of the external flange 1634f of the lower mandrel. A tubular spring retainer 1638 receives and mates with the end of the lower mandrel 1634 and is received and mates with the internal annular recess 1630d of the tubular activation sleeve 1630.

A retainer screw 1642 is received within and is threadably coupled to the internally threaded radial opening 1634b of the lower mandrel 1634 that also extends into the external radial hole 1602o of the upper mandrel 1602.

During operation of the ball gripper assembly 16, in an exemplary embodiment, as illustrated in FIGS. 12A1 to 12A4, the ball gripper assembly may be positioned within the expandable wellbore casing 100 and the internally threaded connection 1602c of the upper mandrel 1602 may be coupled to an externally threaded connection 14a of an end of the casing cutter assembly 14 and the externally threaded connection 1634g of the lower mandrel 1634 may be coupled to an internally threaded connection 18a of an end of the tension actuator assembly 18.

In an alternative embodiment, the internally threaded connection 1602c of the upper mandrel 1602 may be coupled to an externally threaded connection of an end of the tension actuator assembly 18 and the externally threaded connection 1634g of the lower mandrel 1634 may be coupled to an internally threaded connection of an end of casing cutter assembly 14.

In an exemplary embodiment, the deactivation spring 1610 has a greater spring rate than the activation spring 1640. As a result, in an initial operating mode, as illustrated in FIGS. 12A1 to 12A4, a biasing spring force is applied to the deactivation sleeve 1608 and activation sleeve 1630 in a direction 1644 that maintains the activation sleeve in a position relative to the tubular ball race 1628 that maintains the balls 1632 within the radially inward portions of the corresponding tapered annular recesses 1628a of the tubular ball race such that the balls do not extend beyond the perimeter of the activation sleeve to engage the expandable wellbore casing 100.

As illustrated in FIGS. 12C1 to 12C4, in an exemplary embodiment, the ball gripper 16 may be operated to engage the interior surface of the expandable wellbore casing 100 by injecting a fluidic material 1650 into the ball gripper assembly through the longitudinal passages 1602a and 1634aa, of the upper and lower mandrels, 1602 and 1634, respectively.

In particular, when the longitudinal and radial passages, 1602a and 1602b, respectively, of the upper mandrel 1602 are pressurized by the injection of the fluidic material 1650, the internal annular recess 1608c of the deactivation tubular sleeve 1608 is pressurized. When the operating pressure of the fluidic material 1650 within the internal annular recess 1608c of the deactivation tubular sleeve 1608 is sufficient to overcome the biasing spring force of the deactivation spring 1610, the deactivation tubular sleeve is displaced in a direction 1652. As a result, the spring force provided by the activation spring 1640 then may displace the activation tubular sleeve 1630 in the direction 1652 thereby moving the balls 1632 on the corresponding tapered annular recesses 1628a of the tubular ball race 1628 outwardly in a radial direction into engagement with the interior surface of the expandable wellbore casing 100. In an exemplary embodiment, the operating pressure of the fluidic material 1650 sufficient to overcome the biasing spring force of the deactivation spring 1610 was about 100 psi.

In an exemplary embodiment, when the operating pressure of the fluidic material 1650 is reduced, the operating pressure of the fluidic material 1650 within the internal annular recess 1608c of the deactivation tubular sleeve 1608 is no longer sufficient to overcome the biasing spring force of the deactivation spring 1610, and the deactivation tubular sleeve and the activation tubular sleeve 1630 are displaced in a direction opposite to the direction 1652 thereby moving the balls 1632 radially inwardly and out of engagement with the interior surface of the expandable wellbore casing 100.

In an exemplary embodiment, the ball gripper assembly 16 is operated to engage the interior surface of the expandable wellbore casing 100 in combination with the operation of the tension actuator assembly 18 to apply an upward tensile force to one or more elements of the system 10 coupled to and positioned below the tension actuator assembly. As a result, a reaction force comprising a downward tensile force is applied to the lower mandrel 1634 of the ball gripper assembly 16 in a direction opposite to the direction 1652 during the operation of the tension actuator assembly 18. Consequently, due to the geometry of the tapered 1628a of the tubular ball race 1628, the balls 1632 are driven up the tapered annular recesses 1628a of the tubular ball race 1628 with increased force and the contact force between the balls 1632 and the interior surface of the expandable wellbore casing 100 is significantly increased thereby correspondingly increasing the gripping force and effect of the ball gripper assembly.

In an exemplary embodiment, the ball gripper assembly 16 may be operated to radially expand and plastically deform discrete portions of the expandable wellbore casing 100 by controlling the amount of contact force applied to the interior surface of the expandable wellbore casing by the balls 1632 of the ball gripper assembly. In an experimental test of an exemplary embodiment of the ball gripper assembly 16, an expandable wellbore casing was radially expanded and plastically deformed. This was an unexpected result.

Furthermore, in an exemplary embodiment, the upward displacement of the tubular pistons, 18070, 18080, 18090, 18100, and 18110, further causes the external splines 18066d of the connector tube 18066 to engage the internal splines 18014b of the tubular member 18014 and the circumferentially spaced apart teeth 18116g of the connector tube 18116 to engage the circumferentially spaced teeth 18060f of the tubular lower stop 18060. As a result of the interaction of the external splines 18066d of the connector tube 18066 to engage the internal splines 18014b of the tubular member 18014 and the circumferentially spaced apart teeth 18116g of the connector tube 18116 to engage the circumferentially spaced teeth 18060f of the tubular lower stop 18060, torsional loads may be transmitted through the tension actuator assembly 18.

A tubular spacer 2224 receives and is mounted upon the lower tubular mandrel 2204 proximate the other end of the tubular cup seal 2222 at one end and proximate the external flange 2204d of the lower tubular mandrel at another end. A retaining ring 2226 receives and is mounted upon the other end of the tubular spacer 2224 proximate the external flange 2204d of the lower tubular mandrel 2204.

In an exemplary embodiment, during operation of the system 10, the end of the tubular body 200a of the safety sub assembly 20 is coupled to and receives and is coupled to an end of the tension actuator assembly 18 and the other end of the lower tubular mandrel 2204 of the sealing cup assembly 22 is received within and is coupled to an end of the casing lock assembly 24.

In an exemplary embodiment, during operation of the system 10, the tubular cup seals, 2212 and/or 2222, sealingly engage the interior surface of the expandable tubular member 100. In this manner, when an annulus defined between the system 10 and the expandable wellbore casing 10, below the tubular cup seals, 2212 and/or 2222, is pressurized, the resulting pressure differential across the tubular cup seals applies an upward tensile force to the system thereby pulling the adjustable bell section expansion cone assembly 28 and/or the adjustable casing expansion cone assembly 30 through the expandable wellbore casing. In this manner, the adjustable bell section expansion cone assembly 28 and/or the adjustable casing expansion cone assembly 30, if either or both are adjusted to an outside diameter suitable for a radial expansion operation, may radially expand and plastically deform the expandable wellbore casing 100.

In an exemplary embodiment, during operation of the extension actuator assembly 26, as illustrated in FIGS. 15E1 to 15E5, the extension actuator assembly is positioned within the wellbore 102, the internal threaded connection 26002d of the tubular upper tool joint 26002 receives, mates with, and is coupled to an end of the sealing cup assembly 22, and the end of the tubular lower tool joint 26076 is received within, mates with, and is coupled to an end of the adjustable bell section expansion cone assembly 28. In an exemplary embodiment, a portion 100a of the expandable wellbore casing 100 includes internal teeth 100b that engage with, and are coupled to, the external teeth, 26012g and 26014g, of the first and second locking dogs, 26012 and 26014, respectively. In this manner, the expandable wellbore casing 100 is locked to the extension actuator assembly 26 of the system 10.

In an exemplary embodiment, during the operation of the extension actuator assembly 26, a fluidic material 26100 may then be injected into the extension actuator assembly through the longitudinal passages 26004a, 26006a, and 26008a of the upper pull-nut tube 26004, tubular inner mandrel 26006, and lower pull-nut tube 26008, respectively, thereby pressurizing the longitudinal passages of the upper pull-nut tube, tubular inner mandrel, and lower pull-nut tube. As a result, the fluidic material 26100 is also conveyed through the radial passage 26006c of the tubular inner mandrel 26006 into and through an annulus 26102 defined between the tubular inner mandrel and the tubular lock mandrel 26010. The fluidic material 26100 is then conveyed into an annulus 26104 defined between the tubular inner mandrel 26006 and the tubular extender barrel 26052 proximate an end face of the inner mandrel tubular piston 26062.

In an exemplary embodiment, as illustrated in FIGS. 15F1 to 15F5, the continued injection of the fluidic material 26100 into the extension actuator assembly 26 will then displace the inner mandrel tubular piston 26062 downwardly in a direction 26106. As a result, the tubular connecting rod 26060 and the tubular lower tool joint 26076 are also displaced downwardly in the direction 26106.

In an exemplary embodiment, as illustrated in FIGS. 15G1 to 15G5, the continued injection of the fluidic material 26100 into the extension actuator assembly 26 will then further displace the inner mandrel tubular piston 26062 downwardly in the direction 26106 until an end face of the inner flange 26062d of the inner mandrel tubular piston engages an end face of the lower pull-nut tube 26008. As a result, the lower pull-nut tube 26008, the tubular inner mandrel 26006, the upper pull-nut tube 26004, and the tubular lock mandrel 26010 are also displaced downwardly in the direction 26106 thereby shearing the shear pins, 26064a and 26064b, and disengaging the tubular lock mandrel from the tubular release body 26040.

The continued injection of the fluidic material 26100 into the extension actuator assembly 26 will then further displace the tubular lock mandrel 26010 downwardly in the direction 26106 thereby displacing the external flanges, 26010i and 26010j, of the tubular lock mandrel out of engagement with the internal flanges, 26012a and 26012b, and 26014a and 26014b, of the first and second locking dogs, 26012 and 26014, respectively. As a result, a spring bias force in an inner radial direction is applied by the spring arms, 26012d and 26012e, and 26014d and 26014e, of the first and second locking dogs, 26012 and 26014, respectively, to the first and second locking dogs thereby displacing the first and second locking dogs in an inner radial direction out of engagement with the portion 100a of the expandable wellbore casing 100. As a result, the expandable wellbore casing 100 is no longer locked to the first and second locking dogs, 26012 and 26014, of the extension actuator assembly 26.

In an exemplary embodiment, during operation of the extension actuator assembly 26, the expandable wellbore casing 100 may also be un-locked from engagement with the first and second locking dogs, 26012 and 26014, of the extension actuator assembly by increasing the operating pressure of the fluidic material 26100 above a predetermined level sufficient to rupture the burst disk 26034. As a result, the fluidic material 26100 will enter an annulus 26108 defined between the tubular lock mandrel 26010 and the tubular release body 26040. As a result, the tubular lock mandrel 26010 will be displaced downwardly in the direction 26106 thereby displacing the external flanges, 26010i and 26010j, of the tubular lock mandrel out of engagement with the internal flanges, 26012a and 26012b, and 26014a and 26014b, of the first and second locking dogs, 26012 and 26014, respectively. As a result, a spring bias force in an inner radial direction is applied by the spring arms, 26012d and 26012e, and 26014d and 26014e, of the first and second locking dogs, 26012 and 26014, respectively, to the first and second locking dogs thereby displacing the first and second locking dogs in an inner radial direction out of engagement with the portion 100a of the expandable wellbore casing 100. As a result, the expandable wellbore casing 100 is no longer locked to the first and second locking dogs, 26012 and 26014, of the extension actuator assembly 26. In an exemplary embodiment, the predetermined operating pressure of the fluidic material 26100 sufficient to rupture the burst disk 26034 is selected to provide a release of the expandable wellbore casing 100 from engagement with the first and second locking dogs, 26012 and 26104, in the event of an emergency operating condition during the operation of the system 10.

In an exemplary embodiment, the pressurization of the longitudinal passages 26004a, 26006a, and 26008a of the upper pull-nut tube 26004, tubular inner mandrel 26006, and lower pull-nut tube 26008, respectively, caused by the injection of the fluidic material 26100 may be further enhanced by blocking the flow of the fluidic material to those portions of the system 10 downstream from the extension actuator assembly 26 by, for example, blocking flow through a flow restriction defined in one or more of the elements of the system downstream of the extension actuator assembly by placing a ball or plug in one or more of those flow restrictions.

A bypass sleeve 28090 that receives and is mounted upon the release sleeve 28088 includes an internal flange 28090a at one end.

In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, the retracting spring 28044 is compressed and thereby applies a biasing spring force in a direction 28092 from the lower tubular mandrel 28006 to the tubular spring housing 28034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 28052 and the upper expansion segments 28054 out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, an external threaded connection 26a of an end of the extension actuator assembly 26 is coupled to the internal threaded connection 28002d of the upper tubular tool joint 28002 and an internal threaded connection 30a of an end of the adjustable casing expansion cone assembly 30 is coupled to the external threaded connection 28068f of the tubular member 28068.

The upper cam assembly 28052 and the upper expansion segments 28054 may be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by pressurizing an annulus 28094 defined between the lower tubular mandrel 28006 and the tubular spring housing 28034. In particular, injection of fluidic materials into the adjustable bell section expansion cone assembly 28 through the longitudinal passage 28006b of the lower tubular mandrel 28006 and into the radial passage 28006ba may pressurize the annulus 28094 thereby creating sufficient operating pressure to generate a force in a direction 28096 sufficient to overcome the biasing force of the retracting spring 28044. As a result, the spring housing 28034 may be displaced in the direction 28096 relative to the lower tubular mandrel 28006 thereby displacing the tubular upper hinge sleeve 28050, upper cam assembly 28052, and upper expansion segments 28054 in the direction 28096.

In an exemplary embodiment, as illustrated in FIGS. 16P and 16R, the displacement of the upper cam assembly 28052 and upper expansion segments 28054 in the direction 28096 will cause the lower expansion segments 28058 to ride up the cam surfaces 28052e of the cam arms 28052d of the upper cam assembly 28052 while also pivoting about the lower tubular hinge segment 28064, and will also cause the upper expansion segments 28054 to ride up the cam surfaces 28060e of the cam arms 28060d of the lower cam assembly 28060 while also pivoting about the upper tubular hinge segment 28050. In an exemplary embodiment, when the upper and lower expansion segments, 28054 and 28058, are brought into axial alignment, they define an outer expansion surface that is approximately contiguous in a circumferential direction and which provides an outer expansion surface that at least approximates a conical surface.

In an exemplary embodiment, during the operation of the adjustable bell section expansion cone assembly 28, when the upper and lower expansion segments, 28054 and 28058, brought into axial alignment into a radially expanded position, the upper and lower expansion segments, 28054 and 28058, are displaced relative to the expandable wellbore casing 100 to thereby radially expand and plastically deform at least a portion of the expandable wellbore casing. In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable wellbore casing 100, the adjustable bell section expansion cone assembly 28 may then be rotated relative to the expandable wellbore casing to enhance and/or modify the rate at which the expandable wellbore casing is radially expanded and plastically deformed.

In an exemplary embodiment, the upper cam assembly 28052 and the upper expansion segments 28054 may be moved out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by reducing the operating pressure within the annulus 28094.

In an alternative embodiment, as illustrated in FIGS. 16S, 16T, 16U and 16V, during operation of the adjustable bell section expansion cone assembly 28, the upper cam assembly 28052 and the upper expansion segments 28054 may also be moved out of engagement with the lower expansion segments 28058 and the lower cam assembly 28060 by sensing the operating pressure within the longitudinal passage 28006b of the lower tubular mandrel 28006. In particular, as illustrated in FIG. 16T, if the operating pressure within the longitudinal passage 28006b and radial passage 28006bb of the lower tubular mandrel 28006 exceeds a predetermined value, the burst disc 28086 will open the passage 28084a thereby pressurizing the interior of the tubular release sleeve 28088 thereby displacing the tubular release sleeve 28088 downwardly in a direction 28092 away from engagement with the locking dogs 28080.

As a result, as illustrated in FIG. 16U, the locking dogs 28080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 28006 thereby permitting the lower expansion segments 28058 and the lower cam assembly 28060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 16V, the operating pressure within the lower tubular mandrel 28066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 28094 relative to the tubular lower mandrel 28006 and the retracting piston 28074. As a result, the lower tubular mandrel 28066, the lower expansion segments 28058, the lower cam assembly 28060, and tubular lower hinge sleeve 28064 are displaced downwardly in the direction 28094 relative to the tubular spring housing 28034 thereby moving the lower expansion segments 28058 and the lower cam assembly 28060 out of engagement with the upper cam assembly 28052 and the upper expansion segments 28054.

In an exemplary embodiment, as illustrated in FIGS. 16W, 16X, and 16Y, during operation of the adjustable bell section expansion cone assembly 28, the adjustable bell section expansion cone assembly senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 28022 and 28028, lower toggle links, 28024 and 28030, and triggers, 28026 and 28032, and then prevents the engagement of the upper cam assembly 28052 and the upper expansion segments 28054 with the lower expansion segments 28058 and the lower cam assembly 28060.

In particular, as illustrated in FIG. 16W, anytime the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 28026 and 28032, will be pivoted by the engagement arms, 28024d and 28030d, of the lower toggle links, 28024 and 28030, to a position in which the triggers will no longer engage the internal flange 28034d of the end of the tubular spring housing 28034 thereby permitting the displacement of the tubular spring housing in the direction 28096. As a result, the upper cam assembly 28052 and the upper expansion segments 28054 can be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, the upper toggle links, 28022 and 28028, and the lower toggle links, 28024 and 28030, are spring biased towards the position illustrated in FIG. 16W.

Conversely, as illustrated in FIG. 16X, anytime the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 28026 and 28032, will be maintained in a position in which the triggers will engage the internal flange 28034d of the end of the tubular spring housing 28034 thereby preventing the displacement of the tubular spring housing in the direction 28096. As a result, the upper cam assembly 28052 and the upper expansion segments 28054 cannot be brought into engagement with the lower expansion segments 28058 and the lower cam assembly 28060. In an exemplary embodiment, the triggers, 28026 and 28032, are spring biased towards the position illustrated in FIG. 16X.

In an exemplary embodiment, as illustrated in FIG. 16Y, the tubular spring housing 28034 may be displaced upwardly in the direction 28098 even if the upper toggle links, 28022 and 28028, and lower toggle links, 28024 and 28030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, during operation of the adjustable casing expansion cone assembly 30, the retracting spring 30044 is compressed and thereby applies a biasing spring force in a direction 30092 from the lower tubular mandrel 30006 to the tubular spring housing 30034 that, in the absence of other forces, moves and/or maintains the upper cam assembly 30052 and the upper expansion segments 30054 out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, an external threaded connection 20a of an end of the sealing cup assembly 20 is coupled to the internal threaded connection 30002d of the upper tubular tool joint 30002 and an internal threaded connection 30a of an end of the adjustable casing expansion cone assembly 30 is coupled to the external threaded connection 30068f of the tubular member 30068.

The upper cam assembly 30052 and the upper expansion segments 30054 may be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by pressurizing an annulus 30094 defined between the lower tubular mandrel 30006 and the tubular spring housing 30034. In particular, injection of fluidic materials into the adjustable casing expansion cone assembly 30 through the longitudinal passage 30006b of the lower tubular mandrel 30006 and into the radial passage 30006ba may pressurize the annulus 30094 thereby creating sufficient operating pressure to generate a force in a direction 30096 sufficient to overcome the biasing force of the retracting spring 30044. As a result, the spring housing 30034 may be displaced in the direction 30096 relative to the lower tubular mandrel 30006 thereby displacing the tubular upper hinge sleeve 30050, upper cam assembly 30052 , and upper expansion segments 30054 in the direction 30096.

In an exemplary embodiment, as illustrated in FIGS. 17P, 17Q, and 17R, the displacement of the upper cam assembly 30052 and upper expansion segments 30054 in the direction 30096 will cause the lower expansion segments 30058 to ride up the cam surfaces 30052e of the cam arms 30052d of the upper cam assembly 30052 while also pivoting about the lower tubular hinge segment 30064, and will also cause the upper expansion segments 30054 to ride up the cam surfaces 30060e of the cam arms 30060d of the lower cam assembly 30060 while also pivoting about the upper tubular hinge segment 30050. In an exemplary embodiment, when the upper and lower expansion segments, 30054 and 30058, are brought into axial alignment, they define an outer expansion surface that is approximately contiguous in a circumferential direction and which provides an outer expansion surface that at least approximates a conical surface.

In an exemplary embodiment, during the operation of the adjustable casing expansion cone assembly 30, when the upper and lower expansion segments, 30054 and 30058, brought into axial alignment into a radially expanded position, the upper and lower expansion segments, 30054 and 30058, are displaced relative to the expandable wellbore casing 100 to thereby radially expand and plastically deform at least a portion of the expandable wellbore casing. In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable wellbore casing 100, the adjustable casing expansion cone assembly 30 may then be rotated relative to the expandable wellbore casing to enhance and/or modify the rate at which the expandable wellbore casing is radially expanded and plastically deformed.

In an exemplary embodiment, the upper cam assembly 30052 and the upper expansion segments 30054 may be moved out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by reducing the operating pressure within the annulus 30094.

In an alternative embodiment, as illustrated in FIGS. 17S, 17T, 17U and 17V, during operation of the adjustable casing expansion cone assembly 30, the upper cam assembly 30052 and the upper expansion segments 30054 may also be moved out of engagement with the lower expansion segments 30058 and the lower cam assembly 30060 by sensing the operating pressure within the longitudinal passage 30006b of the lower tubular mandrel 30006. In particular, as illustrated in FIG. 17T, if the operating pressure within the longitudinal passage 30006b and radial passage 30006bb of the lower tubular mandrel 30006 exceeds a predetermined value, the burst disc 30086 will open the passage 30084a thereby pressurizing the interior of the tubular release sleeve 30088 thereby displacing the tubular release sleeve 30088 downwardly in a direction 30092 away from engagement with the locking dogs 30080.

As a result, as illustrated in FIG. 17U, the locking dogs 30080 are displaced outwardly in the radial directed and thereby released from engagement with the lower tubular mandrel 30006 thereby permitting the lower expansion segments 30058 and the lower cam assembly 30060 to be displaced downwardly relative to the lower tubular mandrel.

As a result, as illustrated in FIG. 17V, the operating pressure within the lower tubular mandrel 30066 may then cause the lower tubular mandrel to be displaced downwardly in the direction 30094 relative to the tubular lower mandrel 30006 and the retracting piston 30074. As a result, the lower tubular mandrel 30066, the lower expansion segments 30058, the lower cam assembly 30060, and tubular lower hinge sleeve 30064 are displaced downwardly in the direction 30094 relative to the tubular spring housing 30034 thereby moving the lower expansion segments 30058 and the lower cam assembly 30060 out of engagement with the upper cam assembly 30052 and the upper expansion segments 30054.

In an exemplary embodiment, as illustrated in FIGS. 17W, 17X, and 17Y, during operation of the adjustable casing expansion cone assembly 30, the adjustable casing expansion cone assembly senses the diameter of the expandable wellbore casing 100 using the upper toggle links, 30022 and 30028, lower toggle links, 30024 and 30030, and triggers, 30026 and 30032, and then prevents the engagement of the upper cam assembly 30052 and the upper expansion segments 30054 with the lower expansion segments 30058 and the lower cam assembly 30060.

In particular, as illustrated in FIG. 17W, anytime the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has been radially expanded and plastically deformed by the system 10, the triggers, 30026 and 30032, will be pivoted by the engagement arms, 30024d and 30030d, of the lower toggle links, 30024 and 30030, to a position in which the triggers will no longer engage the internal flange 30034d of the end of the tubular spring housing 30034 thereby permitting the displacement of the tubular spring housing in the direction 30096. As a result, the upper cam assembly 30052 and the upper expansion segments 30054 can be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, the upper toggle links, 30022 and 30028, and the lower toggle links, 30024 and 30030, are spring biased towards the position illustrated in FIG. 17W.

Conversely, as illustrated in FIG. 17X, anytime the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10, the triggers, 30026 and 30032, will be maintained in a position in which the triggers will engage the internal flange 30034d of the end of the tubular spring housing 30034 thereby preventing the displacement of the tubular spring housing in the direction 30096. As a result, the upper cam assembly 30052 and the upper expansion segments 30054 cannot be brought into engagement with the lower expansion segments 30058 and the lower cam assembly 30060. In an exemplary embodiment, the triggers, 30026 and 30032, are spring biased towards the position illustrated in FIG. 17X.

In an exemplary embodiment, as illustrated in FIG. 17Y, the tubular spring housing 30034 may be displaced upwardly in the direction 30098 even if the upper toggle links, 30022 and 30028, and lower toggle links, 30024 and 30030, are positioned within a portion of the expandable wellbore casing 100 that has not been radially expanded and plastically deformed by the system 10.

In an exemplary embodiment, as illustrated in FIGS. 17Z1 to 17Z4, 17AA1 to 17AA4, 17AB1 to 17AB4, 17AC1 to 17AC4, 17AD, and 17AE, the tubular spring housing 30034 of the adjustable casing expansion cone assembly 30 defines internal annular recesses 30034k and 300341, spaced apart by an internal flange 30034m, the tubular toggle bushing 30008 defines an external annular recess 30008ac, and the adjustable casing expansion cone assembly further includes pins, 30100a and 30100b and 30102a and 30102b, mounted in holes 30008j and 30008o and 30008k and 30008n, respectively, of the tubular toggle bushing, and a one-shot deactivation device 30104 mounted on the tubular toggle bushing between the pins, 30100a and 30100b and 30102a and 30102b.

An engagement member 30106 that includes a base member 30106a having a tapered end 30106b and a key member 30106c having a tapered end 30106d is received within a portion of the internal annular recess 30104f of the tubular body 30104a and an engagement member 30108 that includes a base member 30108a having a tapered end 30108b and a key member 30108c having a tapered end 30108d is received within an opposite portion of the internal annular recess 30104f of the tubular body 30104a. Spring members, 30110 and 30112, are received within the annular recess 30104f of the tubular body 30104a for biasing the base members, base member 30106a and 30108a, of the engagement members, 30106 and 30108, respectively, radially inwardly relative to the tubular body 30104a.

In an exemplary embodiment, during operation of the adjustable bell section expansion cone assembly 28, as illustrated in FIG. 17Z, the one-shot deactivation device 30104 are positioned proximate and in intimate contact with the pins, 30102a and 30102b, with the tapered ends, 30106b and 30108b, of the base members, 30106a and 30108a, of the engagement members, 30106 and 30108, received within the external annular recess 30008ac of the tubular toggle bushing 30008. When the one-shot deactivation device 30104 is positioned as illustrated in FIG. 17Z, the external annular recess 30104d of the tubular body 30104a of the one-shot deactivation device is moved out of engagement with the engagement arms, 30026d and 30032d, of the triggers, 30026 and 30032, respectively. As a result, the triggers, 30026 and 30032, may operate normally as described above with reference to FIGS. 17W, 17X, and 17Y.

Conversely, in an exemplary embodiment, during operation of the adjustable casing expansion cone assembly 30, as illustrated in FIGS. 17AA1 to 17AA4, the one-shot deactivation device 30104 are positioned proximate and in intimate contact with the pins, 30100a and 30100b, with the tapered ends, 30106b and 30108b, of the base members, 30106a and 30108a, of the engagement members, 30106 and 30108, not received within the external annular recess 30008ac of the tubular toggle bushing 30008. When the one-shot deactivation device 30104 is positioned as illustrated in FIGS. 17AA1 to 17AA4, the external annular recess 30104d of the tubular body 30104a of the one-shot deactivation device is moved into engagement with the engagement arms, 30026d and 30032d, of the triggers, 30026 and 30032, respectively. As a result, the triggers, 30026 and 30032, are deactivated and may not operate normally as described above with reference to FIGS. 17W, 17X, and 17Y.

In an alternative embodiment, the elements of the adjustable casing expansion cone assembly 30 that sense the diameter of the expandable wellbore casing 100 may be disabled or omitted or adjusted to sense any pre-selected internal diameter of the expandable wellbore casing.

In an exemplary embodiment, as illustrated in FIGS. 19A1 to 19A5, during the operation of the packer setting tool assembly 32 and packer assembly 36, the packer setting tool and packer assembly are coupled to one another by inserting the end of the tubular upper adaptor 3602 into the other end of the tubular coupling ring 3244, bringing the circumferentially spaced teeth 3216g of the other end of the tubular bushing 3216 into engagement with the circumferentially spaced teeth 3602e of the end of the tubular upper adaptor, and mounting shear pins, 36100a and 36100b, within the mounting holes, 3244c and 3602c, and, 3244d and 3602d, respectively, of the tubular coupling ring and tubular upper adaptor, respectively. As a result, the tubular mandrel 3206 and tubular stinger 3208 of the packer setting tool assembly 32 are thereby positioned within the longitudinal passage 3604a of the tubular upper mandrel 3604 with the 3208e of the tubular stinger positioned within the longitudinal passage 3646b of the tubular lower mandrel 3646 proximate the collet fingers 3650d of the tubular sliding sleeve valve 3650.

Furthermore, in an exemplary embodiment, during the operation of the packer setting tool 32 and packer assembly 36, as illustrated in FIGS. 20A1 to 20A5, the packer setting tool and packer assembly are positioned within the expandable wellbore casing 100 and an internal threaded connection 30a of an end of the adjustable casing expansion cone assembly 30 receives and is coupled to the external threaded connection 3202f of the end of the tubular adaptor 3202 of the packer setting tool assembly. Furthermore, shear pins, 36102a and 36102b, mounted within the mounting holes, 3658b and 3658c, of the tubular outer sleeve 3658 couple the tubular outer sleeve to the expandable wellbore casing. As a result, torsion loads may transferred between the tubular outer sleeve 3658 and the expandable wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 20B1 to 20B5, a conventional plug 36104 is then injected into the setting tool assembly 32 and packer assembly 36 by injecting a fluidic material 36106 into the setting tool assembly and packer assembly through the longitudinal passages, 3202a, 3204b, 3206b, 3208b, 3650a, 3646a, 3660b, and 3664a of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, tubular sliding sleeve valve 3650, tubular lower mandrel 3646, tubular bypass mandrel 3660, and tubular plug seat 3664, respectively. The plug 36104 is thereby positioned within the longitudinal passage 3664a of the tubular plug seat 3664. Continued injection of the fluidic material 36106 following the seating of the plug 1606 within the longitudinal passage 3664a of the tubular plug seat 3664 causes the plug and the tubular plug seat to be displaced downwardly in a direction 36108 until further movement of the tubular plug seat is prevented by interaction of the set screw 3674 with the external annular recess 3664f of the tubular plug seat. As a result, the flow ports, 3664c and 3664d, of the tubular plug seat 3664 are moved out of alignment with the upper flow ports, 3660c and 3660d, of the tubular bypass mandrel 3660.

In an exemplary embodiment, as illustrated in FIGS. 20C1 to 20C5, after the expandable wellbore casing 100 has been radially expanded and plastically deformed to form at least the bell section 112 of the expandable wellbore casing 100 thereby shearing the shear pins, 36102a and 36102b, the setting tool assembly 32 and packer assembly 36 are then moved upwardly to a position within the expandable wellbore casing 100 above the bell section. The tubular adaptor 3202 is then rotated, by rotating the tool string of the system 10 above the setting tool assembly 32, to displace and position the drag blocks, 3228 and 3230, into engagement with the interior surface of the expandable wellbore casing 100.

As a result of the engagement of the drag blocks, 3228 and 3230, with the interior surface of the expandable wellbore casing 100, further rotation of the drag blocks relative to the wellbore casing is prevented. Consequently, due to the operation and interaction of the threaded connections, 3216d and 3218a, of the tubular bushing 3216 and tubular drag block body 3218, respectively, further rotation of the tubular adaptor 3202 causes the tubular drag block body and setting sleeve 3242 to be displaced downwardly in a direction 36112 relative to the remaining elements of the setting tool assembly 32 and packer assembly 36. As a result, the setting sleeve 3242 engages and displaces the upper tubular spacer ring 3606 thereby shearing the shear pins, 3622a and 3622b, and driving the upper tubular slip 3612 onto and up the angled end face 3620d of the upper tubular wedge 3620 and into engagement with the interior surface of the expandable wellbore casing 100. As a result, longitudinal displacement of the upper tubular slip 3612 relative to the expandable wellbore casing 100 is prevented. Furthermore, as a result, the 3246b collet fingers of the tubular retaining collet 3246 are disengaged from the tubular upper adaptor 3602.

In an alternative embodiment, after the drag blocks, 3228 and 3230, engage the interior surface of the expandable wellbore casing 100, an upward tensile force is applied to the tubular support member 12, and the ball gripper assembly 16 is then operate to engage the interior surface of the expandable wellbore casing. The tension actuator assembly 18 is then operated to apply an upward tensile force to the tubular adaptor 3202 thereby pulling the upper tubular spacer ring 3606, lower tubular spacer ring 3610, upper tubular slip 3612, lower tubular slip 3616, upper tubular wedge 3620, lower tubular wedge 3624, upper tubular extrusion limiter 3628, lower tubular extrusion limiter 3634, and central tubular elastomeric element 3644 upwardly into contact with the 3242 thereby compressing the upper tubular spacer ring, lower tubular spacer ring, upper tubular slip, lower tubular slip, upper tubular wedge, lower tubular wedge, upper tubular extrusion limiter, lower tubular extrusion limiter, and central tubular elastomeric element. As a result, the upper tubular slip 3612, lower tubular slip 3616, and central tubular elastomeric element 3644 engage the interior surface of the expandable wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 20D1 to 20D5, an upward tensile force is then applied to the tubular adaptor 3202 thereby compressing the lower tubular slip 3616, lower tubular wedge 3624, central elastomeric packer element 3644, upper tubular extrusion limiter 3628, and upper tubular wedge 3620 between the lower tubular spacer ring 3610 and the stationary upper tubular slip 3612. As a result, the lower tubular slip 3616 is driven onto and up the angled end face 3624d of the lower tubular wedge 3624 and into engagement with the interior surface of the expandable wellbore casing 100, and the central elastomeric packer element 3644 is compressed radially outwardly into engagement with the interior surface of the expandable tubular member. As a result, further longitudinal displacement of the upper tubular slip 3612, lower tubular slip 3616, and central elastomeric packer element 3644 relative to the expandable wellbore casing 100 is prevented.

In an exemplary embodiment, as illustrated in FIGS. 20E1 to 20E6, continued application of the upward tensile force to tubular adaptor 3202 will then shear the shear pins, 1602a and 1602b, thereby disengaging the setting tool assembly 32 from the packer assembly 36.

In an exemplary embodiment, as illustrated in FIGS. 20F1 to 20F6, with the drag blocks, 3228 and 3230, in engagement with the interior surface of the expandable wellbore casing 100, the tubular adaptor 102 is further rotated thereby causing the tubular drag block body 3218 and setting sleeve 3242 to be displaced further downwardly in the direction 36113 until the tubular drag block body and setting sleeve are disengaged from the tubular stinger 3208. As a result, the tubular stinger 3208 of the setting tool assembly 32 may then be displaced downwardly into complete engagement with the tubular sliding sleeve valve 3650.

In an exemplary embodiment, as illustrated in FIGS. 20G1 to 20G6, a fluidic material 36114 is then injected into the setting tool assembly 32 and the packer assembly 36 through the longitudinal passages 3202a, 3204b, 3206b, 3208b, 3604b, 3650a, and 3646b of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, tubular upper mandrel 3604, tubular sliding sleeve valve 3650, and tubular lower mandrel 3646, respectively. Because, the plug 36104 is seated within and blocks the longitudinal passage 3664a of the tubular plug seat 3664, the longitudinal passages 3604b, 3650a, and 3646b of the tubular upper mandrel 3604, tubular sliding sleeve valve 3650, and tubular lower mandrel 3646 are pressurized thereby displacing the tubular upper adaptor 3602 and tubular upper mandrel 3604 downwardly until the end face of the tubular upper mandrel impacts the end face of the upper tubular spacer ring 3606.

In an exemplary embodiment, as illustrated in FIGS. 20H1 to 20H5, the setting tool assembly 32 is brought back into engagement with the packer assembly 36 until the engagement shoulder 3208e of the other end of the tubular stinger 3208 engages the collet fingers 3650d of the end of the tubular sliding sleeve valve 3650. As a result, further downward displacement of the tubular stinger 3208 displaces the tubular sliding sleeve valve 3650 downwardly until the radial flow ports, 3650b and 3650c, of the tubular sliding sleeve valve are aligned with the flow ports, 3646e and 3646f, of the tubular lower mandrel 3646. A hardenable fluidic sealing material 36116 may then be injected into the setting tool assembly 32 and the packer assembly 36 through the longitudinal passages 3202a, 3204b, 3206b, 3208b, and 3650a of the tubular adaptor 3202, tubular upper mandrel 3204, tubular mandrel 3206, tubular stinger 3208, and tubular sliding sleeve valve 3650, respectively. The hardenable fluidic sealing material may then flow out of the packer assembly 36 through the upper flow ports, 3658d and 3658e, into the annulus between the expandable wellbore casing 100 and the wellbore 102.

The tubular sliding sleeve valve 3650 may then be returned to its original position, with the radial flow ports, 3650b and 3650c, of the tubular sliding sleeve valve out of alignment with the flow ports, 3646e and 3646f, of the tubular lower mandrel 3646. The hardenable fluidic sealing material 36116 may then be allowed to cure before, during, or after the continued operation of the system 10 to further radially expand and plastically deform the expandable wellbore casing.

In an alternative embodiment, as illustrated in FIGS. 21 and 21 A to 21 AX, the packer assembly 36 includes an upper tubular spacer ring 36200 receives and mates with the end of the tubular upper mandrel 3604 and includes an angled end face 36200a that includes a plurality of spaced apart radial grooves 36200b and another end face that is positioned proximate to an end face of the tubular upper adaptor 3602 is coupled to the tubular upper mandrel by shear pins, 36202a, 36202b, 36202c, and 36202d.

In an exemplary embodiment, during the radial displacement of the slip elements, 36206a and 36208a, the retaining pins, 36206au and 36208au, respectively, and the mounting pins, 36206at and 36208at, respectively, maintain the slip elements in an evenly spaced apart configuration. In an exemplary embodiment, during the operation of the packer assembly 36, the mounting pins, 36214ak and 36216ak, maintain the extrusion limiter elements, 36214a and 36216a, of the upper and lower tubular extrusion limiter assemblies, 36214 and 36216, respectively, in an evenly spaced apart configuration. The operation of the alternative embodiment of the packer assembly 36 described above with reference to FIGS. 21 and 21A to 21AX is otherwise substantially identical to the operation of the packer assembly described above with reference to FIGS. 20A1 to 20A5, 20B1 to 20B5, 20C1 to 20C5, 20D1 to 20D5, 20E1 to 20E6, 20F1 to 20F6, 20G1 to 20G6, and 20H1 to 20H5.

The tubular bushing 3816 further includes radial holes, 3816i and 3816j, through which the keys, 3812a and 3812b, respectively, radially extend so that the keys, 3812a and 3812b, lock the bushing 3816 to the upper mandrel 3804. The tubular bushing 3816 further includes an external annular recess 3816k.

A tubular support or tubular spacer 3818 defines a longitudinal passage 3818a for receiving the upper mandrel 3804, includes an annular portion 3818b at one end that is near or adjacent the other end of the tubular adaptor 3802, further defines radial passages, 3818c and 3818d, and further includes an external annular recess 3818e, an external annular recess 3818f, an internal annular recess 3818g, and counterbores, 3818h and 3818i, that are axially aligned with the holes, 3804k and 38041, respectively, of the upper mandrel 3804. The external annular recesses, 3818e and 3818f, define an annular protrusion 3818j. Screws 3820a and 3820b are threadably engaged with the counterbores, 3818h and 3818i, respectively, of the tubular spacer 3818, and extend into the holes 3804m and 38041, respectively, of the upper mandrel 3804, thereby coupling the tubular spacer 3818 to the upper mandrel 3804.

A retaining ring 3824 is disposed in the external annular recess 3804e of the upper mandrel 3804 and extends into the internal annular recess 3822c of the packer cup sleeve 3822, retaining the end of the packer cup sleeve 3822 in the internal annular recess 3818g of the tubular spacer 3818, thereby coupling the packer cup sleeve 3822 to the upper mandrel 3804.

A packer cup 3824 is disposed in the external annular recess 3822b of the packer cup sleeve 3822, and a packer ring 3825 is disposed in the external annular recess 3822b of the packer cup sleeve 3822 and is axially positioned between the packer cup 3824 and the tubular spacer 3818.

An end of a tubular support or tubular upper sleeve 3826 that defines a longitudinal passage 3826a and includes an internal annular recess 3826b, an internal annular recess 3826c, an internal annular recess 3826d, an internal annular recess 3826e, an internal annular recess 3826f, and an internal threaded connection 3826g, is positioned near or adjacent the annular portion 3818b of the tubular spacer 3818 so that the annular portion 3818b of the tubular spacer 3818 is axially positioned between the tubular adaptor 3802 and the upper sleeve 3826. Radial holes, 3826h and 3826i, extend through the internal annular recess 3826b, and radial holes, 3826j and 3286k, extend through the internal annular recess 3826d.

The upper retaining dogs, 3828a and 3828b, are adapted to further extend into the external annular recess 3818e to releasably engage the tubular spacer 3818, as shown in FIG. 22A and under conditions to be described.

A retaining ring 3829 extends into the external annular recess 3804f of the upper mandrel 3804 and extends into an internal annular recess 3830a of a lower dog retainer 3830. The lower dog retainer 3830 further includes an internal annular recess 3830b, an external annular recess 3830c, counterbores, 3830d and 3830e, that are axially aligned with the external mounting holes, 3804o and 3804p, respectively, of the upper mandrel 3804, and radial holes 3830f and 3830g. Screws, 3832a and 3832b, are threadably engaged with the counterbores, 3830d and 3830e, respectively, of the lower dog retainer 3830, and extend into the external mounting holes, 3804o and 3804p, respectively, of the upper mandrel 3804, which, along with the retaining ring 3829, couple the lower dog retainer 3830 to the upper mandrel 3804.

A tubular support or tubular retaining sleeve 3834 includes an external annular recess 3834a and an external annular recess 3834b, and mates with the exterior surface of the upper mandrel 3804 and with the interior surface of the upper sleeve 3826. Lower retaining dogs, 3836a and 3836b, including respective internal annular recesses, 3836aa and 3836ab, engage the internal annular recess 3826d and extend through the radial holes, 3830f and 3830g, respectively, to mate with the retaining sleeve 3834. It is understood that the retaining sleeve 3834 retains the lower retaining dogs, 3836a and 3836b, so that any relative movement between the lower retaining dogs, 3836a and 3836b, and the upper mandrel 3804 is substantially prevented. Rupture discs, 3838a and 3838b, are received and mounted within the radial passages, 3804m and 3804n.

An external threaded connection 3840a of an external annular recess 3840b of a tubular support or spring mandrel 3840 is received within the internal annular recess 3826f of the upper sleeve 3826 and is coupled to the internal threaded connection 3826g of the upper sleeve 3826. The spring mandrel 3840 further includes an external annular recess 3840c, an external annular recess 3840d, an external annular recess 3840e, an external threaded connection 3840f, an internal annular recess 3840g and an internal annular recess 3840h. A locking dog 3841 is received within the internal annular recess 3840h of the spring mandrel 3840 and engages the exterior surface of the bushing 3816.

An internal threaded connection 3842a of a tubular support or tubular spring retainer 3842 is coupled to the external threaded connection 3840f of the spring mandrel 3840, and includes a external flange 3842b. A tubular spring sleeve 3844 engages the external flange 3842b of the spring retainer 3842 and includes an internal annular recess 3844a, radial passages, 3844b and 3844c, an external annular recess 3844d and an external threaded connection 3844e. A compressible element such as a spring 3846 is retained and extends within an annular region 3848 defined by the internal annular recess 3844a of the spring sleeve 3844, the exterior of the spring retainer 3842 and at least an end of the spring mandrel 3840, thereby circumferentially extending about the tubular upper mandrel 3804.

A tubular locking dog retainer 3843 is received within the internal annular recess 3826f of the upper sleeve 3826 and includes an internal flange 3843a that engages the keys, 3812a and 3812b, and is received within the internal annular recess 3840g of the spring mandrel 3840.

An internal threaded connection 3850a of an end of a tubular setting sleeve 3850 that defines a longitudinal passage 3850b, radial passages, 3850c and 3850d, radial passages, 3850e and 3850f, and includes an internal flange 3850g at another end, engages the external threaded connection 3844e of the spring retainer 3842.

An internal flange 3852a of a tubular coupling ring 3852 that defines a longitudinal passage 3852b and radial passages, 3852c and 3852d, and includes an external annular recess 3852e, receives and mates with the external flange 3816h of the bushing 3816. An internal flange 3854a of a tubular retaining collet 3854 that includes a plurality of axially extending collet fingers 3854b, each finger 3854b having internal flanges 3854c at an end of each collet finger, receives the tubular coupling ring 3852 and engages the external annular recess 3852e of the tubular coupling ring 3852.

In an exemplary embodiment, as illustrated in FIGS. 23A to 23E, during the operation of the packer setting tool assembly 38 and the packer assembly 36, the packer setting tool assembly 38 and the packer assembly 36 are coupled to one another by inserting the end of the tubular upper adaptor 3602 into the other end of the tubular coupling ring 3852, bringing the circumferentially spaced teeth 3816f of the other end of the tubular bushing 3816 into engagement with the circumferentially spaced teeth 3602e of the end of the tubular upper adaptor 3602, and mounting shear pins, 36100a and 36100b, within the radial passages, 3852c and 3852d, respectively, of the tubular coupling ring 3852 and within the mounting holes, 3602c and 3602d, respectively, of the tubular upper adaptor 3602. As a result, the tubular mandrel 3806 and the tubular stinger 3808 of the packer setting tool assembly 38 are thereby positioned within the longitudinal passage 3604b of the tubular upper mandrel 3604 with the engagement shoulder 3808e of the tubular stinger 3808 positioned within the longitudinal passage 3646b of the tubular lower mandrel 3646 proximate the collet fingers 3650d of the tubular sliding sleeve valve 3650.

In an exemplary embodiment, the packer setting tool assembly 38 and the packer assembly 36 are positioned within the expandable wellbore casing 100, and the internal threaded connection 30a of an end of the adjustable casing expansion cone assembly 30 receives and is coupled to the external threaded connection 3802f of the tubular adaptor 3802 of the packer setting tool assembly 38. The upper retaining dogs, 3828a and 3828b, and/or the outer diameter of the tubular upper sleeve 3826, are sized so that the upper retaining dogs, 3828a and 3828b, and/or at least a portion of the exterior surface of the tubular upper sleeve 3826, engage the wellbore casing 100, and the tubular upper sleeve 3826 is radially inwardly biased so that the upper retaining dogs, 3828a and 3828b, extend into the external annular recess 3818e and are forced to mate with the tubular spacer 3818, thereby releasably engaging the tubular spacer 3818, including releasably engaging the annular protrusion 3818j. Furthermore, in an exemplary embodiment, torque pins, 3676d and 3676e, may be mounted within mounting holes, 3676f and 3676g, respectively, of the tubular bypass sleeve 3676 to couple the tubular bypass sleeve 3676 to the expandable wellbore casing 100. As a result, torsion loads may be transferred between the tubular bypass sleeve 3676 and the expandable wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 24A to 24E, the plug 36104 is then injected into the setting tool assembly 38 and the packer assembly 36 by injecting the fluidic material 36106 into the setting tool assembly 38 and the packer assembly 36 through the longitudinal passages, 3802a, 3804b, 3806b, 3808b, 3650a, 3646b and 3664a of the tubular adaptor 3802, tubular upper mandrel 3804, tubular mandrel 3806, tubular stinger 3808, tubular sliding sleeve valve 3650, tubular lower mandrel 3646, and tubular plug seat 3664, respectively. The plug 36104 is thereby positioned within the longitudinal passage 3664a of the tubular plug seat 3664. The flow ports, 3664c and 3664d, of the tubular plug seat 3664 are aligned with the upper flow ports, 3660c and 3660d, respectively, of the tubular bypass mandrel 3660.

In an exemplary embodiment, as illustrated in FIGS. 25A to 25E, continued injection of the fluidic material 36106 following the seating of the plug 36104 within the longitudinal passage 3664a of the tubular plug seat 3664 causes the plug and the tubular plug seat to be displaced downwardly in the direction 36108 until further movement of the tubular plug seat is prevented by the interaction of the circumferentially-spaced set screws 3674 and 3675 with the external annular recess 3664f of the tubular plug seat. As a result, the flow ports, 3664c and 3664d, of the tubular plug seat 3664 are moved out of alignment with the upper flow ports, 3660c and 3660d, respectively, of the tubular bypass mandrel 3660.

In an exemplary embodiment, as illustrated in FIGS. 26A to 26E, continued injection of the fluidic material 36106 following the prevention of further movement of the tubular plug seat 3664 actuates the extension actuator assembly 26 in a manner substantially similar to that described above so that the extension actuator assembly 26 pushes the adjustable bell section expansion cone assembly 28, the adjustable casing expansion cone assembly 30, the packer setting tool assembly 38 and the packer assembly 36 out of the wellbore casing 100. Since the packer setting tool assembly 38 extends outside of the wellbore casing 100, the upper retaining dogs, 3828a and 3828b, and the tubular upper sleeve 3826 no longer engage the wellbore casing 100 and thus the tubular upper sleeve 3826 is no longer radially inwardly biased. As a result, the upper retaining dogs, 3828a and 3828b, are released from mating with the tubular spacer 3818 and engaging the annular protrusion 3818j.

In an exemplary embodiment, it is understood that if it is desired to cease further operation of the packer assembly 36 when the packer setting tool assembly 38 and the packer assembly 36 extend outside of the wellbore casing 100, the upper sleeve 3826 is displaced in a direction toward the packer assembly 36 in a manner to be described below, thereby causing the spring sleeve 3844, the setting sleeve 3850 and the upper tubular spacing ring 3606 of the packer assembly 36 to move in a direction towards the upper tubular wedge 3620 in a manner described below. As a result, the upper tubular slip 3612 is forced to move along the upper tubular wedge 3620 until the upper tubular slip 3612 is pushed off of the packer assembly 36, thereby permitting the packer setting tool assembly 38 and the packer assembly 36 to be retrieved.

In an exemplary embodiment, it is understood that if the packer setting tool assembly 38 and the packer assembly 36 are not able to be extended outside of the wellbore casing 100, the upper retaining dogs, 3828a and 3828b, continue to mate with the tubular spacer 3818 and to engage the annular protrusion 3818j, thereby preventing the upper sleeve 3826 from moving in a direction towards the packer assembly 36 in a manner, and for reasons, to be described below, and permitting the packer setting tool assembly 38 and the packer assembly 36 to be retrieved.

In an exemplary embodiment, the wellbore casing 100 is radially expanded and plastically deformed using the ball gripper assembly 16, the tension actuator assembly 18, the casing lock assembly 24, the extension actuator assembly 26 and the expansion cone assemblies, 28 and 30, in a manner of operation substantially similar to any one of the manners of operation described and/or referenced above, and/or any combination thereof.

In an exemplary embodiment, as illustrated in FIGS. 27A to 27E, after the expandable wellbore casing 100 has been radially expanded and plastically deformed to form at least the bell section 112 of the expandable wellbore casing 100, thereby shearing the torque pins, 3676d and 3676e, the packer setting tool assembly 38 and the packer assembly 36 are then moved upwardly to a position within the expandable wellbore casing 100 above the bell section 112.

Continued injection of the fluidic material 36106, with any further movement of the tubular plug seat 3664 still being prevented, increases the operating pressure of the fluidic material 36106 above a predetermined level sufficient to rupture the rupture discs, 3838a and 3838b. As a result, the fluidic material 36106 enters an annulus 3856 defined by the tubular upper mandrel 3804 and the tubular upper sleeve 3826. As a result, the retaining sleeve 3834 is displaced downwardly in the direction 36108, and engages the internal annular recess 3830b of the lower dog retainer 3830. As a result, the lower retaining dogs, 3836a and 386b, no longer engage the internal annular recess 3826d of the upper sleeve 3826, but instead move radially inward to engage the external annular recesses, 3834a and 3834b, of the tubular retaining sleeve 3834. Thus, it is understood that the lower retaining dogs, 3836a and 3836b, are released from the upper sleeve 3826.

In an exemplary embodiment, as illustrated in FIGS. 28A to 28E, the operating pressure of the fluidic material 36106 in the annulus 3856 causes the upper sleeve 3826, the spring mandrel 3840, the spring sleeve 3844 and the setting sleeve 3850 to be displaced in the downward direction 36108 until the setting sleeve 3850 engages the upper tubular spacer ring 3606 of the packer assembly 36, which is mated with the upper tubular slip 3612 of the packer assembly 36.

The operating pressure of the fluidic material 36106 in the annulus 3856 continues to cause the upper sleeve 3826, the spring mandrel 3840 and the spring sleeve 3844 to be displaced in the downward direction 36108, relative to the setting sleeve 3850. As a result, the external annular recess 3840d of the spring mandrel 3840 compresses the spring 3846 against an end face 3844aa defined by the internal annular recess 3844a of the spring sleeve 3844.

When the spring 3846 is fully compressed, the operating pressure of the fluidic material 36106 in the annulus 3856 causes the upper sleeve 3826 to force the upper tubular slip 3612 of the packer assembly 36, via force transmission across the spring mandrel 3840, the compressed spring 3846, the spring sleeve 3844, the setting sleeve 3850 and the upper tubular spacer ring 3606, to move along the upper tubular wedge 3620 of the packer assembly 36. In an exemplary embodiment, it is understood that the shear pins, 3608a and 3608b, may be broken to enable the upper tubular slip 3612 to move along the upper tubular wedge 3620. In an exemplary embodiment, it is further understood that one or more of the slip retaining bands, 3612c, 3612d, 3612e, 3612f, 3612g, 3614a, 3614b, 3614c, 3614d, and 3614e, if present, may be broken to enable the upper tubular slip 3612 to move along the upper tubular wedge 3620.

The upper sleeve 3826 continues to force the upper tubular slip 3612 to move along the upper tubular wedge 3620 until the spring mandrel 3840 engages the external flange 3816d of the tubular bushing 3816, the end of which, in turn, is engaged with the external flange 3804h of the upper mandrel 3804. Thus, any further displacement of the upper sleeve 3826 in the downward direction 36108 is substantially prevented.

As a result of the displacement of the upper sleeve 3826 in the downward direction 36108, the keys, 3812a and 3812b, are released from their engagement with the internal flange 3843a of the locking dog retainer 3843. As another result of the displacement of the upper sleeve 3826 in the downward direction 36108, the locking dog 3841 is displaced in the downward direction 36018 so that the locking dog 3841 is received within the external annular recess 3816k of the bushing 3816.

In an exemplary embodiment, it is understood that the keys, 3812a and 3812b, lock the bushing 3816 to the upper mandrel 3804, and allow torque and load top to be transmitted from the upper mandrel 3804 to the tubular bushing 3816, and to the packer assembly 36 via the above-described coupling between the packer setting tool assembly 38 and the packer assembly 36. In an exemplary embodiment, it is understood that the keys, 3812a and 3812b, prevent the stinger 3808 from engaging and displacing the sliding sleeve valve 3650, thereby preventing the radial flow ports, 3650b and 3650c, of the sliding sleeve valve 3650 from being axially aligned with the flow ports, 3646e and 3646f, of the tubular lower mandrel 3646 of the packer assembly 36.

In an exemplary embodiment, as illustrated in FIGS. 29A through 29E, although any further displacement of the upper sleeve 3826 in the downward direction 36108 is prevented, the fully compressed spring 3846 begins to uncompress, and extends to force the spring sleeve 3844, the setting sleeve 3850 and the upper tubular spacing ring 3606 of the packer assembly 36 in the downward direction 36108, thereby causing the upper tubular slip 3612 to further move along the upper tubular wedge 3620 and against the interior surface of the wellbore casing 100, until the upper tubular slip 3612 is set against the wellbore casing 100. As a result, further longitudinal displacement of the upper tubular slip 3612 relative to the wellbore casing 100 is prevented.

In an exemplary embodiment, it is understood that, by preventing any further displacement of the upper sleeve 3826 in the downward direction and by permitting the compressed spring 3846 to uncompress and force the upper tubular slip 3612 to set against the wellbore casing 100, the upper tubular slip 3612 is substantially prevented from applying an impact load against the interior surface of the wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 30A through 30E, after the upper tubular slip 3612 is set against the wellbore casing 100, an upward tensile force is applied to the tubular support member 12, and the ball gripper assembly 16 is then operated to engage the interior surface of the wellbore casing 100 in a manner of operation substantially similar to any one of the manners of operation described and/or referenced above, and/or any combination thereof. The tension actuator assembly 18 is then operated to apply a tensile force to the tubular adaptor 3802 in an upward direction 3860, in any one of the manners of operation described and/or referenced above, and/or any combination thereof, thereby compressing the lower tubular slip 3616, the lower tubular wedge 3624, the lower tubular extrusion limiter 3634, the central elastomeric packer element 3644, the upper tubular extrusion limiter 3628 and the upper tubular wedge 3620 between the lower tubular spacer ring 3610 and the stationary upper tubular slip 3612. As a result, the lower tubular slip 3616 moves along the lower tubular wedge 3624 and into engagement with the interior surface of the wellbore casing 100, forcing the lower tubular slip 3616 to set against the interior surface of the wellbore casing 100. As another result, the elastomeric packer element 3644 is compressed radially outwardly into engagement with the interior surface of the wellbore casing 100, forcing the packer element 3644 to set against the interior surface of the wellbore casing 100. As a result, further longitudinal displacement of the upper tubular slip 3612, the lower tubular slip 3616 and the packer element 3644, relative to the wellbore casing 100, is prevented.

Continued application of the upward tensile force to the tubular adaptor 3802 will then shear the shear pins, 36100a and 36100b, thereby disengaging and releasing the packer setting tool assembly 38 from the packer assembly 36.

In an exemplary embodiment, the packer setting tool assembly 38 continues to move away from the packer assembly 36, in the direction 3860, at least until at least a portion of the stinger 3808 no longer extends within the longitudinal passage 3602a of the tubular upper adaptor 3602 of the packer assembly 36, and the adjustable expansion cone assembly 30 engages and mates with at least a portion of the interior surface of the unexpanded portion of the wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 31A through 31E, continued injection of the fluidic material 36106 causes the packer setting tool assembly 38 to move in the direction 36108 until the tubular spacer ring 3606 engages the stationary upper tubular slip 3612. The continued injection of the fluidic material 36106 also causes the packer assembly 36, including the tubular upper mandrel 3604, to move in the direction 36108 so that the lower tubular spacer ring 3610 moves away from the stationary lower tubular slip 3616. As a result of the continued injection of the fluidic material 36106, the portion of the interior of the wellbore casing 100 within which at least a portion of the packer assembly 36 extends is pressurized, thereby testing the ability of the engagement between the wellbore casing 100 and one or more of the upper tubular slip 3612, the upper tubular extrusion limiter 3628, the elastomeric packer element 3644, the lower tubular extrusion limiter 3634 and the lower tubular slip 3616 to maintain a pressure seal against the interior surface of the wellbore casing 100.

In an exemplary embodiment, as illustrated in FIGS. 32A through 32E, the continued injection of the fluidic material 36106 is stopped, and the operating pressure within the longitudinal passages, 3802a, 3804b, 3806b, 3808b, 3650a, 3646b and 3664a of the tubular adaptor 3802, tubular upper mandrel 3804, tubular mandrel 3806, tubular stinger 3808, tubular sliding sleeve valve 3650, tubular lower mandrel 3646, and tubular plug seat 3664, respectively, is released. The packer setting tool assembly 38 is brought back into engagement with the packer assembly 36 until the engagement shoulder 3808e of the other end of the tubular stinger 3808 engages the collet fingers 3650d of the end of the tubular sliding sleeve valve 3650. As a result, further downward displacement of the tubular stinger 3808 displaces the tubular sliding sleeve valve 3650 downwardly until the radial flow ports, 3650b and 3650c, of the tubular sliding sleeve valve 3650 are aligned with the radial flow ports, 3646e and 3646f, of the tubular lower mandrel 3646. During the downward displacement of the tubular stinger 3808, the locking dog 3841 engages the external annular recess 3816k of the bushing 3816 and the internal annular recess 3840h of the spring mandrel 3840 to further separate the bushing 3816, the coupling ring 3852 and the retaining collet 3854 from the packer assembly 36.

In an exemplary embodiment, as illustrated in FIGS. 33A through 33E, a hardenable fluidic sealing material 36116 may then be injected into the packer setting tool assembly 38 and the packer assembly 36 through the longitudinal passages 3802a, 3804b, 3806b, 3808b and 3650a of the tubular adaptor 3802, tubular upper mandrel 3804, tubular mandrel 3806, tubular stinger 3808 and the tubular sliding sleeve valve 3650, respectively. The hardenable fluidic sealing material 3116 may then flow out of the longitudinal passage 3650a, through the radial ports, 3650b and 3650c, of the tubular sliding sleeve valve 3650, through the radial ports, 3646e and 3646f, of the tubular lower mandrel 3646, and into an annulus 36118 defined by the exterior surface of the tubular lower mandrel 3646 and the interior surface of the tubular outer sleeve 3658. The hardenable sealing material 3116 may then flow out of the annulus 36118, through the upper flow ports, 3658d and 3658e, and the lower flow ports, 3658f and 3658g, and into the annulus between the wellbore casing 100 and the wellbore 102. In an exemplary embodiment, in addition to, or instead of the injection of the hardenable fluidic sealing material 36116, it is understood that other well fluids may be injected into the packer setting tool assembly 38 and the packer assembly 36 in a manner similar to the injection of the hardenable fluidic sealing material 36116.

The tubular sliding sleeve valve 3650 may then be returned to its original position, with the radial flow ports, 3650b and 3650c, of the tubular sliding sleeve valve out of alignment with the flow ports, 3646e and 3646f, of the tubular lower mandrel 3646. The hardenable fluidic sealing material 36116 may then be allowed to cure before, during, or after the continued operation of the system 10 to further radially expand and plastically deform the expandable wellbore casing 100.

In an exemplary embodiment, it is understood that if it is desired to retrieve the packer setting tool assembly 38 when the packer assembly 36 is in the bell section 112 of the wellbore casing 100, the packer setting tool assembly 38 and the packer assembly 36 are operated in the above-described manner so that the upper tubular slip 3612, the lower tubular slip 3616 and the packer element 3644 engage and set against the interior surface of the bell section 112 of the wellbore casing 100, thereby permitting the packer setting tool assembly 38 to be retrieved, that is, to be moved in a direction away from the upper tubular slip 3612, the lower tubular slip 3614 and the packer element 3644.

The internal threaded connection 40660g of the coupling 40660 of the middle subassembly 40600 receives and is coupled to the external threaded connection 40406f of the connecting rod 40406 of the middle subassembly 40400. The set screws, 40662a and 40662b, extend through the openings, 40660e and 40660f, respectively, and into the external annular recess 40406j to lock the coupling 40660 to the connecting rod 40406. The internal threaded connection 40606e of the barrel 40606 of the middle subassembly 40600 receives and is coupled to the external threaded connection 40402d of the middle lift adapter 40402 of the middle subassembly 40400 so that the openings, 40606f and 40606g, are generally axially aligned with the openings, 40402j and 40402k, respectively. A torque pin 50a extends through the openings 40606f and 40402j, and a torque pin 50b extends through the openings 40606g and 40402k, to lock the barrel 40606 to the middle lift adapter 40402.

The internal threaded connection 40460g of the coupling 40460 of the middle subassembly 40400 receives and is coupled to the external threaded connection 40202d of the adapter 40202 of the lower subassembly 40200. The set screws, 40462a and 40462b, extend through the openings, 40460e and 40460f, respectively, and into the external annular recess 40202m to lock the coupling 40460 to the adapter 40202. The internal threaded connection 40406e of the barrel 40406 of the middle subassembly 40400 receives and is coupled to the external threaded connection 40204e of the lower lift adapter 40204 of the lower subassembly 40200 so that the openings, 40406f and 40406g, are generally axially aligned with the openings, 40204j and 40204k, respectively.

The external threaded connection 40238g of the lower nipple 40238 of the lower subassembly 40200 is received within and coupled to the internal threaded connection 20a of the end of the safety sub assembly 20 so that the openings, 40238h and 40238i, of the lower nipple 40238 are generally aligned with openings, 20b and 20c, of the safety sub assembly 20. A torque pin 54a extends through the openings 40238h and 20b, and a torque pin 54b extends through the openings 40238i and 20c, to lock the lower nipple 40238 to the safety sub assembly 20.

In several exemplary embodiments, one or more of the elements of the system 10 coupled to and positioned below the lower nipple 40238 may be removed from the system 10, or may be repositioned relative to one or more other elements of the system 10. For example, the safety sub assembly 20, the sealing cup assembly 22, the casing lock assembly 24 and the extension actuator assembly 26 may be removed from the system 10 so that the lower nipple 40238 of the lower subassembly 40200 of the tension actuator assembly 40 is directly coupled, rather than indirectly coupled, to the expansion cone assembly 28. For another example, the safety sub assembly 20, the sealing cup assembly 22, the casing lock assembly 24, the extension actuator assembly 26 and the expansion cone assembly 28 may be removed from the system 10 so that the lower nipple 40238 of the lower subassembly 40200 of the tension actuator assembly 40 is directly coupled, rather than indirectly coupled, to the expansion cone assembly 30.

In several exemplary embodiments, one or more of the above-described elements of the tension actuator assembly 40 may be omitted, at least in part, and/or combined, at least in part, with one or more other elements, or sub-elements thereof, of the tension actuator assembly 40 and/or the system 10.

In an exemplary embodiment, as illustrated in FIGS. 39a through 39T, during operation of the tension actuator assembly 40, the tension actuator assembly is positioned within the casing 100. The tension actuator assembly 40 is initially placed in an extended configuration by pulling the expansion cone assembly 28 and/or the expansion cone assembly 30 against the inside surface of the casing 100 and/or against the end of the casing 100. More particularly, the tubular support member 12 is moved upwardly in a direction 56, causing the cutter assembly 14 and the ball gripper assembly 16 to also move upwardly in the direction 56, and causing the top subassembly 401400, the upper lift adapter 401202 of the upper subassembly 401200, the middle lift adapters 401002, 40802, 40602 and 40402 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively, the retainers 401004, 40804, 40604 and 40404 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively, the barrels 401006, 40806, 40606 and 40406 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively, and the lower lift adapter 40204 and the torque retainer 40206 of the lower subassembly 40200 to also move upwardly in the direction 56. As a result, the torque lugs 40204a of the lower lift adapter 40204 of the lower subassembly 40200 engage and mesh with torque lugs 40202l of the adapter 40202 of the lower subassembly. As a result of the engagement and meshing of the torque lugs 40204a with the torque lugs 40202l, the continued movement of the tubular support 12 in the direction 56 causes all of the elements of the lower subassembly 40200, the middle subassemblies 40400, 40600, 40800 and 401000, the upper subassembly 401200, and the top subassembly 401400, to move upwardly in the direction 56 until the expansion cone assembly 28 and/or the expansion cone assembly 30 is pulled against the inside surface of the casing 100 and/or against the end of the casing 100. As a result, the tension actuator assembly 40 is in an extended configuration.

When the tension actuator assembly 40 is in its extended configuration, an axial distance 58 is defined between the end of the internal tapered surface 401266c of the guide 401266 of the upper subassembly 401200 and the internal threaded connection 401404a of the coupling 401404 of the top subassembly 401400, and an axial distance 60 is defined between the torque lugs 40206f of the torque retainer 40206 of the lower subassembly 40200 and the torque lugs 40236g of the coupling 40236 of the lower subassembly 40200. In an exemplary embodiment, the distances, 58 and 60, may be about equal to one another.

When the tension actuator assembly 40 is in its extended configuration, the engagement and meshing of the torque lugs 40204a with the torque lugs 40202l permits torque to be transmitted through the tension actuator assembly 40. For example, torque may be applied to the top subassembly 401400, thereby transmitting torque through the upper lift adapter 401202, the retainer 401204 and the barrel 401206 of the upper subassembly 401200; the middle lift adapters 401002, 40802, 40602 and 40402 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; the retainers 401004, 40804, 40604 and 40404 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; the barrels 401006, 40806, 40606 and 40406 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; and the lower lift adapter 40204 of the lower subassembly 40200, due to the above-described couplings between these elements, and the torque is transmitted from the lower lift adapter 40204 to the lower connecting rod 40210 via the engagement and meshing of the torque lugs 40204a with the torque lugs 40202l and the above-described coupling of the adapter 40202 with the lower connecting rod 40210. As a result, the torque is transmitted from the lower connecting rod 40210 to one or more of the elements of the system 10 coupled to and positioned below the lower nipple 40238 via the above-described coupling between the lower connecting rod 40210 and the coupling 40236, and the coupling between the coupling 40236 and the lower nipple 40238.

In an exemplary embodiment, the ball gripper assembly 16 is operated to engage and hold the position of the casing 100, relative to the tubular support member 12, in a manner of operation substantially similar to any one of the manners of operation described and/or referenced above, and/or any combination thereof.

In an exemplary embodiment, as illustrated in FIGS. 40A through 40T, during operation of the tension actuator assembly 40, and after the tension actuator assembly 40 is positioned in the casing 100, the tension actuator assembly 40 is placed in its extended configuration, and the ball gripper assembly 16 is operated, fluidic material 62 is injected into the tension actuator assembly 40 through the passages 401404b, 401402a, 401266b, 401208a, 401008a, 40808a, 40608a, 40408a, 40202a, 40210b and 40238b. The injected fluidic material 62 will also pass through the radial openings, 401008b and 401008c, and into an adjustable annular region 64 generally defined by the inside surface of the barrel 401206 and the outside surface of the connecting rod 401008, through the radial openings, 40808b and 40808c, and into an adjustable annular region 66 generally defined by the inside surface of the barrel 401006 and the outside surface of the connecting rod 40808, through the radial openings, 40608b and 40608c, and into an adjustable annular region 68 generally defined by the inside surface of the barrel 40806 and the outside surface of the connecting rod 40608, through the radial openings, 40408b and 40408c, and into an adjustable annular region 70 generally defined by the inside surface of the barrel 40606 and the outside surface of the connecting rod 40408. The fluidic material 62 will also pass through the radial passages, 40202b and 40202c, and into an adjustable annular region 72 generally defined by the inside surface of the barrel 40406 and the outside surface of the connecting rod 40210.

In an exemplary embodiment, as illustrated in FIGS. 41A through 41X, the operating pressure of the fluidic material 62 may then be increased by, for example, controllably blocking or limiting the flow of the fluidic material 62 through the passage 40238b and/or increasing the operating pressure of the outlet of a pumping device for injecting the fluidic material 62 into the tension actuator assembly 40. In an exemplary embodiment, one or more plug elements or operating plugs such as, for example, the plug 36104, may be injected into the tension actuator assembly 40 and through the passages 401404b, 401402a, 401266b, 401208a, 401008a, 40808a, 40608a, 40408a, 40202a, 40210b and 40238b, and the internal tapered surface 401266c of the guide 401266 may facilitate the guiding of the plug 36104 into the passage 401208a of the connecting rod 401208.

As a result of the increased operating pressure of the fluidic material 62, the operating pressure within each of the annular regions 64, 66, 68, 70 and 72 is increased so that the total of the forces generated within each of the annular regions is sufficient to displace the guide 401266, the connecting rod 401208, the retaining dogs 401234 and 401236, the upper thimble 401240, the backup ring 401242, the inside thimble 401244, the cup 401246, the sleeve 401248, the outside thimble 401250, the backup ring 401252, the inside thimble 401254, the cup 401256, the tubular sleeve 401258 and the collar 401260 of the upper subassembly 401200 in an upward direction 74.

Moreover, the connecting rod 40608, the retaining dogs 40634 and 40636, the upper thimble 40640, the backup ring 40642, the inside thimble 40644, the cup 40646, the sleeve 40648, the outside thimble 40650, the backup ring 40652, the inside thimble 40654, the cup 40656, the tubular sleeve 40658 and the coupling 40660 of the middle subassembly 40600 are also displaced in the upward direction 74.

During the above-described displacement of several components of the tension actuator assembly 40 in the direction 74, an upward tensile force is applied to all elements of the system 10 coupled to and positioned below the lower nipple 40238. As a result, the expansion cone assembly 28 and/or 30 radially expands and plastically deforms at least a portion of the casing 100, in a manner of operation substantially similar to any of the manners of operation of the expansion cone assembly 28 and/or 30 described and/or referenced above, and/or any combination thereof.

As a result of the above-described displacement of several components of the tension actuator assembly 40 in the direction 74, the tension actuator assembly 40 is in a retracted configuration. In an exemplary embodiment, when the tension actuator assembly 40 is in a retracted configuration, the torque lugs 40206f engage and mesh with the torque lugs 40236g, and the respective values of the distances 58 and 60 are negligible, that is, equal to, or nearly equal to, zero. In an exemplary embodiment, when the distances 58 and 60 are each about equal to the other when the tension actuator assembly 40 is in the extended configuration, and when the distances 58 and 60 are each negligible when the tension actuator assembly 40 is in the retracted configuration, the distances 58 and 60 are each about equal to the stroke length of the tension actuator assembly 40 when the tension actuator assembly 40 is in the extended configuration; that is, the stroke length of the tension actuator assembly 40 is about equal to the overall axial distance that each of the connecting rods 401208, 401008, 40808, 40608, 40408 and 40210 travels during the above-described displacement of several components of the tension actuator assembly 40 in the direction 74.

In an exemplary embodiment, the stroke length of the tension actuator assembly 40 may be about 35 feet. In several exemplary embodiments, the casing 100 may be in the form of a wide variety of types and configurations of casing, including a wide variety of sizes of casing. In an exemplary embodiment, the casing 100 may be, for example, 7-⅝ inch casing. In an exemplary embodiment, the transportable length of each of the above-described subassemblies 40200, 40400, 40600, 40800, 401000, 401200 and 401400 in the tension actuator assembly 40 may be, for example, equal to or less than about 45 feet.

In an exemplary embodiment, the stroke length of the tension actuator assembly 40 may be increased by coupling, with flush joint connections, connecting-rod extensions and barrel extensions between, for example, the lower subassembly 40200 and the middle subassembly 40400, the middle subassembly 40400 and the middle subassembly 40600, the middle subassembly 40600 and the middle subassembly 40800, the middle subassembly 40800 and the middle subassembly 401000, and the middle subassembly 401000 and the upper subassembly 401200, of the tension actuator assembly 40. In an exemplary embodiment, the stroke length of the tension actuator assembly 40 may be increased up to, for example, 90 feet. In an exemplary embodiment, a connecting-rod extension may be coupled to the lower connecting rod 40210 of the lower subassembly 40200, a connecting-rod extension may be coupled to each of the connecting rods 40408, 40608, 40808 and 401008, a barrel extension may be coupled to each of the barrels 40406, 40606, 40806 and 401006, and a barrel extension may be coupled to the barrel 401206. In an exemplary embodiment, the stroke length of the tension actuator assembly 40 may be increased up to, for example, 90 feet, while the transportable length of each of the above-described subassemblies 40200, 40400, 40600, 40800, 401000, 401200 and 401400 in the tension actuator assembly 40 may be, for example, equal to or less than about 45 feet.

When the tension actuator assembly 40 is in its retracted configuration, the engagement and meshing of the torque lugs 40206f with the torque lugs 40236g permits torque to be transmitted through the tension actuator assembly 40. For example, torque may be applied to the top subassembly 401400, thereby transmitting torque through the upper lift adapter 401202, the retainer 401204 and the barrel 401206 of the upper subassembly 401200; the middle lift adapters 401002, 40802, 40602 and 40402 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; the retainers 401004, 40804, 40604 and 40404 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; the barrels 401006, 40806, 40606 and 40406 of the middle subassemblies 401000, 40800, 40600 and 40400, respectively; and the lower lift adapter 40204 and the torque retainer 40206 of the lower subassembly 40200, due to the above-described couplings between these elements, and the torque is transmitted from the torque retainer 40206 to the coupling 40236 via the engagement and meshing of the torque lugs 40206f with the torque lugs 40236g. As a result, the torque is transmitted from the coupling 40236 to one or more elements of the system 10 coupled to and positioned below the lower nipple 40238 via the above-described coupling between the coupling 40236 and the lower nipple 40238. The torque may also be transmitted from the coupling 40236 to the lower connecting rod 40210 via the above-described coupling between the coupling 40236 and the lower connecting rod 40210.

In an exemplary embodiment, after the tension actuator assembly 40 has been placed in its retracted configuration from its extended configuration, thereby causing radial expansion and plastic deformation of the casing 100 as described above, the ball gripper assembly 16 may then be operated to release the casing 100, and the tubular support 12 may be moved upwardly to permit the tension actuator assembly 40 to again be placed in its extended configuration. The above-described operation of the tension actuator assembly 40 may then be repeated to radially expand and plastically deform at least another portion of the casing 100. As a result, in an exemplary embodiment, the casing 100 may be radially expanded and plastically deformed without subjecting the casing 100 to the increased operating pressure of the fluidic material 62, and/or the increased operating pressure within each of the annular regions 64, 66, 68, 70 and 72. As a result, in an exemplary embodiment, the casing 100 may be generally prevented from bursting in response to the increased operating pressure of the fluidic material 62, and/or the increased operating pressure within each of the annular regions 64, 66, 68, 70 and 72, especially if the increased operating pressure of the fluidic material 62, and/or the increased operating pressure within each of the annular regions 64, 66, 68, 70 and 72, is higher than the burst pressure of the casing 100 and/or is higher than the pressure rating of the casing connections in the casing 100. As another result, in an exemplary embodiment, the radial expansion and plastic deformation of the casing 100 does not require the casing 100 to maintain pressure integrity. That is, the tension actuator assembly 40 may be operated to radially expand and plastically deform the casing 100 even if the casing 100 has lost pressure integrity, or has negligible pressure integrity, due to, for example, one or more holes or openings in the casing 100, one or more parted portions of the casing 100 and/or other causes.

In an exemplary embodiment, during further operation of the system 4500, as illustrated in FIGS. 51, 51a, 51b, 51c, and 51d, continued injection of the fluidic material 5002 into the system 4500 may then pressurize the interior passages of the system sufficient to operate the actuator 45104 to displace the tubular support member 45106 in a direction opposite the direction 45108ae. As a result, in an exemplary embodiment, the expansion cone elements 45018a pivot in an outer radial direction relative to the tubular support member 45102 and are driven up the circumferentially spaced apart ramp members 45106b of the tubular support member 45106.

As a result, in an exemplary embodiment, the circumferentially spaced apart coupling elements 45108bb are elastically deformed in an outer radial direction and the resulting spring force maintains the corresponding expansion cone elements 45018a in intimate contact with the corresponding circumferentially spaced apart ramp members 45106b of the tubular support member 45106.

In an exemplary embodiment, during further operation of the system 4500, as illustrated in FIG. 52, continued injection of fluidic materials into the system 4500 may pressurize an interior region 4514a of the wellbore casing 4514. As a result, the 4510 may be decoupled from the 4512, and the remainder of the 4500 may be displaced upwardly in a direction 5202 relative to the 4512. As a result, the wellbore casing 4514 may be radially expanded and plastically deformed. In an exemplary embodiment, during the further operation of the system 4500, a pressure differential is created within the wellbore casing 4514 across one or both of the cup seals 45110a and 45110b.
