Description

BACKGROUND

Traditional joints that perform simultaneous anchoring and sealing between two different parts may be achieved by using a combination of geometric mechanical joining methods, and sealing elements or inserts (e.g., elastomeric/plastic/metal). For example, geometric mechanical joining methods including non-sealing threads, snap rings, collets, Ratch Latch™, lock rings, bolting/riveting and other type of latching methods are often used. In other instances, simultaneous sealing and anchoring maybe achieved by using special sealing threads, such as premium threads or torqued connections, but typically only on round tubular geometries. Other traditional methods of joining to enable simultaneous anchoring and sealing include friction/interference/shrink fits, swaging, welding/brazing and similar fusion methods.

Certain other non-traditional joints are also used to anchor and seal two different parts relative to one another. In certain instances, non-traditional shape memory alloys are used to form the anchor and seal. In other instances, non-traditional shrink rings are used to form the anchor and seal. The above methods (e.g., traditional and non-traditional alike), however, have tradeoffs between simplicity, cost or function. For example, some are limited by geometry, such as threads, which can only be applied on round tubular sections.

DETAILED DESCRIPTION

In the drawings and descriptions that follow, like parts are typically marked throughout the specification and drawings with the same reference numerals, respectively. The drawn figures are not necessarily to scale. Certain features of the disclosure may be shown exaggerated in scale or in somewhat schematic form and some details of certain elements may not be shown in the interest of clarity and conciseness. The present disclosure may be implemented in embodiments of different forms.

Specific embodiments are described in detail and are shown in the drawings, with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that illustrated and described herein. It is to be fully recognized that the different teachings of the embodiments discussed herein may be employed separately or in any suitable combination to produce desired results.

Unless otherwise specified, use of the terms “connect,” “engage,” “couple,” “attach,” or any other like term describing an interaction between elements is not meant to limit the interaction to direct interaction between the elements and may also include indirect interaction between the elements described.

Unless otherwise specified, use of the terms “up,” “upper,” “upward,” “uphole,” “upstream,” or other like terms shall be construed as generally toward the surface of the ground; likewise, use of the terms “down,” “lower,” “downward,” “downhole,” or other like terms shall be construed as generally toward the bottom, terminal end of a well, regardless of the wellbore orientation. Use of any one or more of the foregoing terms shall not be construed as denoting positions along a perfectly vertical axis. Unless otherwise specified, use of the term “subterranean formation” shall be construed as encompassing both areas below exposed earth and areas below earth covered by water such as ocean or fresh water.

The present disclosure describes a method for joining two or more similar and/or dissimilar materials using a novel expandable metal, as the base for the joint. As will be understood more fully below, the expandable metal begins as a metal, and after being subjected to an activation fluid, changes to a hard, fluid impermeable material. In certain embodiments, the hard, fluid impermeable material contains a certain amount of unreacted expandable metal, and thus may be self-healing and/or self-repairing.

The expandable metal has many different applications when joining two materials together, as well as provides certain advantages (e.g., incremental and radical advantages) over existing joints. For example, the expandable metal may be used to join any combination of two or more materials with various shapes and different interfacing/mating geometries, either as a primary joint and/or seal, or as a back-up method to currently available methods. Additionally, the expandable metal may have certain in-situ healing and/or/repairing properties, if for example degradation of the joint subsequently occurs. The expandable metal may be used to join round, circular but not round, or other mathematical geometries, all the same. Additionally, the expandable metal may be used along with threads, lock-rings, seal-rings, latches, etc., to attach and seal, while maintaining 360 degree contact. Moreover, the expandable metal may be used simply as an attachment method for structural load bearing, such as self-grown—snap rings, collets, ball profiled locks, dimpled surface locks, shear screws, shear rings, shear pins etc.

The expandable metal may additionally be modified to include various fillers, which could change one or more properties of the resulting joint. For example, the expandable metal could be modified to result in enhanced and/or performance calibrated material properties, such as: improved mechanical properties—shear strength, impact toughness, tensile strength, modulus of elasticity, elongation, thermal expansion etc.; improved electrical properties—conductivity, resistivity etc.; improved optical properties—refractive index, light transmissibility etc.; improved chemical properties—activation time, reaction rate etc.; as well as improved physical properties, magnetic properties and acoustical properties, to name a few.

Ultimately, expandable metal based joints (e.g., anchored and/or sealed joints) offer cost effective and relatively quick in-house solutions (applied at the time of assembly, activated prior to being placed downhole, active after being placed downhole, etc.) to joining two or more parts, in place of interference/shrink fits or welding/brazing, among others. Accordingly, the expandable metal based joints, could be used for one or more of the (e.g., non-limiting) following applications: 1) Intelligent completions, including shrink-fits for sliding sleeve carbide carriers for interval control valves, shrink-fits for deflectors and/or shroud adapters for water-injection in interval control valves, shrink-fits for Venturi flow meter mandrels, permanent monitoring gauges and pressure-temperature sensor weld joints, and gauge, sensors, modules and SOV weld joints in Imperium system; 2) Multilaterals—joining y-block junctions with their associated wellbore legs (e.g., D-tube, round, special profile cross section, double barrel, etc.); 3) Screens—various weldable parts and joints; 4) Sand Control—inflow control devices, autonomous inflow control devices, etc.; 5) any welded and/or brazed joint or profile, such as—weld cap, insert retentions, atmospheric chamber; and 6) any body internal design features in a design where a thread is used due to design constraints to create simultaneous seal and anchor.

Additionally, expanded metal joints may be used in certain applications where the heat required to weld or braze two surfaces together negatively affects the metallurgy of the surfaces. For instance, in certain high H₂S or CO₂ applications, the features of the well must be manufactured according to National Association of Corrosion Engineers (NACE) standards. Unfortunately, the heat required to weld or braze the two surface together damage the corrosion resistance of the two surfaces, which means they no longer meet the NACE standard, and thus cannot be used. Nevertheless, the expanded metal joints function the same way as the welded or brazed joints, if not better, and do not require the extreme heat to form the same. Accordingly, the expanded metal joints could be used and still meet the NACE standard.

FIG. 1 illustrates a well system 100 designed, manufactured, and operated according to one or more embodiments of the disclosure, and including a multilateral junction 175 (e.g., y-block and two or more wellbore legs) and/or interval control valve (ICV) 180 designed, manufactured and operated according to one or more embodiments of the disclosure. In accordance with at least one embodiment, the multilateral junction 175 and/or ICV 180 could include expandable metal joints or expanded metal joints according to any of the embodiments, aspects, applications, variations, designs, etc. disclosed in the following paragraphs.

The well system 100 includes a platform 120 positioned over a subterranean formation 110 located below the earth's surface 115. The platform 120, in at least one embodiment, has a hoisting apparatus 125 and a derrick 130 for raising and lowering a downhole conveyance 140, such as a drill string, casing string, tubing string, coiled tubing, etc. Although a land-based oil and gas platform 120 is illustrated in FIG. 1, the scope of this disclosure is not thereby limited, and thus could potentially apply to offshore applications. The teachings of this disclosure may also be applied to other land-based multilateral wells different from that illustrated.

The well system 100 in one or more embodiments includes a main wellbore 150. The main wellbore 150, in the illustrated embodiment, includes tubing 160, 165, which may have differing tubular diameters. Extending from the main wellbore 150, in one or more embodiments, may be one or more lateral wellbores 170. Furthermore, a plurality of multilateral junctions 175 may be positioned at junctions between the main wellbore 150 and the lateral wellbores 170. Each multilateral junction 175 may comprise a y-block designed, manufactured or operated according to the disclosure. As discussed above, the multilateral junctions 175 may include expandable metal or expanded metal according to any of the embodiments, aspects, applications, variations, designs, etc. disclosed in the following paragraphs, including the use of expandable metal or expanded metal for the joints therein.

The well system 100 may additionally include one or more ICVs 180 positioned at various positions within the main wellbore 150 and/or one or more of the lateral wellbores 170. The ICVs 180 may comprise an ICV designed, manufactured or operated according to the disclosure. As discussed above, one or more of the ICVs 180 could include expandable metal or expanded metal according to any of the embodiments, aspects, applications, variations, designs, etc. disclosed in the following paragraphs, for example with respect to any of the joints within the ICVs 180. The well system 100 may additionally include a control unit 190. The control unit 190, in this embodiment, is operable to provide control to or received signals from, one or more downhole devices.

In certain embodiments, the multilateral junction 175 and/or ICV 180 may include one or more expanded metal joints (e.g., anchor, seal, or anchor and seal joints) that were formed with pre-expansion metal (e.g., metal configured to expand in response to hydrolysis) in accordance with one or more embodiments of the disclosure. After the pre-expansion metal has been subjected to an activation agent, the one or more joints would include expanded metal in accordance with one or more embodiments of the disclosure. In accordance with one or more embodiments of the disclosure, at least a portion of the expanded metal joint additionally includes residual unreacted expandable metal therein, and thus retains a self-healing and/or self-repairing aspect.

The expanded metal joint, in at least one embodiment, expands to generally fill the overlapping space between the two or more features that are being joined. The overlapping space in at least one embodiment includes the space created between opposing surfaces of the two or more features, regardless of the relative orientation (e.g. parallel with the longitudinal axis of the two or more features, perpendicular with the longitudinal axis of the two or more features, or angled relative to the longitudinal axis of the two or more features). The phrase generally fill, as that term is used herein, is intended to convey that at least 20 percent of the overlapping space is filled. In other embodiments, the expanded metal joint expands to substantially fill, and in yet other embodiments expands to excessively fill, the overlapping space between the two or more features that are being joined. The phrase substantially fill, as that term is used herein, is intended to convey that at least 50 percent of the overlapping space is filled, and the phrase excessively fill, as that term is used herein, is intended to convey that at least 75 percent of the overlapping space is filled.

The expanded metal joint in the overlapping space, in one or more embodiments, has a volume of no more than 25,000 cm³. In yet another embodiment, the overlapping space has a volume of no more than 7,750 cm³. In certain embodiments, the expanded metal joint has a volume ranging from about 31.5 mm³ to about 5,813 cm³. In yet another embodiment, the expanded metal joint has a volume ranging from about 4,282 mm³ to about 96,700 mm³. Nevertheless, the volume of the expanded metal joint should be designed to provide an adequate anchor and/or seal for the two or more features being joined (e.g., without overly expanding to the areas outside of the overlapping space), but otherwise is not limited to any specific values.

Again, in certain embodiments, the expanded metal joint includes residual unreacted expandable metal therein. For example, in certain embodiments the expanded metal joint is intentionally designed to include the residual unreacted expandable metal therein. The residual unreacted expandable metal has the benefit of allowing the expanded metal joint to self-heal if cracks or other anomalies subsequently arise. Nevertheless, other embodiments may exist wherein no residual unreacted expandable metal exists in the expanded metal joint.

The expandable metal, in some embodiments, may be described as expanding to a cement like material. In other words, the metal goes from metal to micron-scale particles and then these particles expand and lock together to, in essence, lock the expanded metal joint in place. The reaction may, in certain embodiments, occur in less than 24 hours in a reactive fluid and acceptable temperatures. Nevertheless, the time of reaction may vary depending on the reactive fluid, the expandable metal used, thickness of the expandable metal used, and the temperature.

In some embodiments, the reactive fluid may be a brine solution such as may be produced during well completion activities, and in other embodiments, the reactive fluid may be one of the additional solutions discussed herein. The metal, pre-expansion, is electrically conductive in certain embodiments. The metal may be machined to any specific size/shape, extruded, forged, cast, printed or other conventional ways to get the desired shape of a metal, as will be discussed in greater detail below. Metal, pre-expansion, in certain embodiments has a yield strength greater than about 8,000 psi, e.g., 8,000 psi+/−50%.

The hydrolysis of the metal can create a metal hydroxide. The formative properties of alkaline earth metals (Mg—Magnesium, Ca—Calcium, etc.) and transition metals (Zn—Zinc, Al—Aluminum, etc.) under hydrolysis reactions demonstrate structural characteristics that are favorable for use with the present disclosure. Hydration results in an increase in size from the hydration reaction and results in a metal hydroxide that can precipitate from the fluid.

The hydration reactions for magnesium is:

Mg+2H₂O->Mg(OH)₂+H₂,

where Mg(OH)₂ is also known as brucite. Another hydration reaction uses aluminum hydrolysis. The reaction forms a material known as Gibbsite, bayerite, and norstrandite, depending on form. The hydration reaction for aluminum is:

Al+3H₂O->Al(OH)₃+3/2H₂.

Another hydration reactions uses calcium hydrolysis. The hydration reaction for calcium is:

Ca+2H₂O->Ca(OH)₂+H₂,

Where Ca(OH)₂ is known as portlandite and is a common hydrolysis product of Portland cement. Magnesium hydroxide and calcium hydroxide are considered to be relatively insoluble in water. Aluminum hydroxide can be considered an amphoteric hydroxide, which has solubility in strong acids or in strong bases.

In an embodiment, the metallic material used can be a metal alloy. The metal alloy can be an alloy of the base metal with other elements in order to either adjust the strength of the metal alloy, to adjust the reaction time of the metal alloy, or to adjust the strength of the resulting metal hydroxide byproduct, among other adjustments. The metal alloy can be alloyed with elements that enhance the strength of the metal such as, but not limited to, Al—Aluminum, Zn—Zinc, Mn—Manganese, Zr—Zirconium, Y—Yttrium, Nd—Neodymium, Gd—Gadolinium, Ag—Silver, Ca—Calcium, Sn—Tin, and Re—Rhenium, Cu—Copper. In some embodiments, the alloy can be alloyed with a dopant that promotes corrosion, such as Ni—Nickel, Fe—Iron, Cu—Copper, Co—Cobalt, Ir—Iridium, Au—Gold, C—Carbon, Ga—Gallium, In—Indium, Mg—Mercury, Bi—Bismuth, Sn—Tin, and Pd—Palladium. The metal alloy can be constructed in a solid solution process where the elements are combined with molten metal or metal alloy. Alternatively, the metal alloy could be constructed with a powder metallurgy process. The metal can be cast, forged, extruded, sintered, welded, mill machined, lathe machined, stamped, eroded or a combination thereof.

Optionally, non-expanding components may be added to the starting metallic materials. For example, ceramic, elastomer, plastic, epoxy, glass, or non-reacting metal components can be embedded in the expanding metal or coated on the surface of the metal. Alternatively, the starting metal may be the metal oxide. For example, calcium oxide (CaO) with water will produce calcium hydroxide in an energetic reaction. Due to the higher density of calcium oxide, this can have a 260% volumetric expansion where converting 1 mole of CaO goes from 9.5 cc to 34.4 cc of volume. In one variation, the expanding metal is formed in a serpentinite reaction, a hydration and metamorphic reaction. In one variation, the resultant material resembles a mafic material. Additional ions can be added to the reaction, including silicate, sulfate, aluminate, carbonate, and phosphate. The metal can be alloyed to increase the reactivity or to control the formation of oxides.

The expandable metal can be configured in many different fashions, as long as an adequate volume of material is available for fully expanding. For example, the expandable metal may be formed into a single long member, multiple short members, rings, alternating steel and expandable rubber and expandable metal rings, among others.

Turning to FIGS. 2A through 2C, depicted are various different manufacturing states for a junction 200 designed, manufactured and operated according to the disclosure. FIG. 2A illustrates the junction 200 pre-expansion, FIG. 2B illustrates the junction 200 post-expansion, and FIG. 2C illustrates the junction 200 post-expansion and containing residual unreacted expandable metal therein. The junction 200 of FIGS. 2A through 2C includes a first member 210 and second member 220. In accordance with one or more embodiments of the disclosure, the first member 210 comprises a first material (M1) and the second member 220 comprises a second material (M2). In certain embodiments, the first material (M1) and the second material (M2) are the same material, but in other embodiments the first material (M1) and the second material (M2) are different materials.

In the illustrated embodiment, and in accordance with the disclosure, the first member 210 and the second member 220 overlap one another. Depending on the design, the overlap may be face-to-face, end-to-end, but-to-but, or any other overlap, as well as combinations of the same. The first member 210 and the second member 220, in the illustrated embodiment, thus define an overlapping space 230. The overlapping space 230, in at least one or more embodiments, defines the type of junction. For example, in the embodiment of FIGS. 2A through 2C, the overlapping space 230 is a single step overlapping space, which would tend to form a single step joint, as further discussed below.

While not required, the first member 210 and the second member 220 are a first tubular and a second tubular in the embodiment discussed with regard to FIGS. 2A through 2C. Accordingly, the first member 210 and the second member 220 define a centerline (CO in the embodiments shown. In other embodiments, however, one or both of the first member 210 or the second member 220 are not tubulars. In at least one embodiment, the second member 220 is a collet being coupled to the first member 210.

In the illustrated embodiment, the first member 210 has a first wall thickness (t₁) proximate the overlapping space 230 and the second member 220 has a second wall thickness (t₂) proximate the overlapping space 230. In accordance with at least one embodiment, the first wall thickness (t₁) and the second wall thickness (t₂) are no more than 5.0 cm. Nevertheless, in at least one other embodiment, the first wall thickness (t₁) and the second wall thickness (t₂) are no more than 1.25 cm. Nevertheless, in at least yet another embodiment, the first wall thickness (t₁) and the second wall thickness (t₂) are between about 0.15 cm and about 0.635 cm. Nevertheless, in at least yet another embodiment, the first wall thickness (t₁) and the second wall thickness (t₂) are no more than 0.7 cm. Thus, in accordance with the embodiment shown, the first member 210 and the second member 220 are thin walled structures.

In the illustrated embodiment, the first member 210 has a first inside diameter (d₁) proximate the overlapping space 230 and the second member 220 has a second inside diameter (d₂) proximate the overlapping space 230. In the illustrated embodiment, the overlapping space 230 (and thus the resulting expanded metal joint) is positioned proximate an end of the first member 210 or second member 220. In accordance with at least one embodiment, the overlapping space 230 (and thus the resulting expanded metal joint) is positioned less than a distance (D_p) from the end of the first member 210 or second member 220. The distance (D_p), in one or more embodiments, is equal to or less than four times the first inside diameter (d₁). The distance (D_p), in one or more other embodiments, is equal to or less than two times the first inside diameter (d₁).

In the illustrated embodiment, the first member 210 and the second member 220 overlap by a distance (D_o). In at least one embodiment, the overlap distance (D_o) between the first member 210 and the second member 220 is less than 120 cm. In yet another embodiment, the overlap distance (D_o) between the first member 210 and the second member 220 is less than 40 cm. In yet another embodiment, the overlap distance (D_o) between the first member 210 and the second member 220 is less than 10 cm. Essentially, as the first member 210 and second member 220 are thin walled structures in the embodiments of FIGS. 2A through 2C, the overlap distance (D_o) is not significant.

In the illustrated embodiment, the first member 210 has a length (L₁) and the second member 220 has a length (L₂). In the illustrated embodiment, at least a portion of the overlapping space 230 (and thus the resulting expanded metal joint) is parallel with the length (L₁). Further to this embodiment, at least another portion of the overlapping space 230 (and thus the resulting expanded metal joint) is perpendicular with the length (L₁). As will be discussed below, other embodiments exist wherein at least a portion of the overlapping space 230 (and thus the resulting expanded metal joint) is angled relative to the length (L₁).

With reference to FIG. 2A, a pre-expansion joint 240 is located at least partially within the overlapping space 230. The pre-expansion joint 240, in accordance with one or more embodiments of the disclosure, comprises a metal configured to expand in response to hydrolysis. The pre-expansion joint 240, in the illustrated embodiment, may comprise any of the expandable metals discussed above, or any combination of the same. The pre-expansion joint 240 may have a variety of different lengths and thicknesses, for example depending on the amount of anchor, as well as whether it is desired for the pre-expansion joint 240 to act as a seal when subjected to activation fluid, and remain within the scope of the disclosure.

With reference to FIG. 2B, illustrated is the pre-expansion joint 240 illustrated in FIG. 2A after subjecting it to an activation fluid to expand the metal in the overlapping space 230, and thereby form an expanded metal joint 250. In the illustrated embodiment, the expanded metal joint 250 generally fills the overlapping space, as that term is defined above. In yet other embodiments, the expanded metal joint 250 substantially fills the overlapping space, as that term is defined above, or in yet other embodiments, the expanded metal joint 250 excessively fills the overlapping space, as that term is defined above.

Notwithstanding the foregoing, the expanded metal joint 250 may have a variety of different volumes and remain within the scope of the disclosure. Such volumes, as expected, are a function of the size of the overlapping space 230, the volume of the pre-expansion joint 240, and the composition of the pre-expansion joint 240, among other factors. Nevertheless, in at least one embodiment, the expanded metal joint 250 has a volume of no more than 25,000 cm³. In yet another embodiment, the overlapping space has a volume of no more than 7,750 cm³. In at least one other embodiment, the expanded metal joint 250 has a volume ranging from about 31.5 mm³ to about 5,813 cm³, and in yet another embodiment, the expanded metal joint 250 has a volume ranging from about 4,282 mm³ to about 96,700 mm³.

With reference to FIG. 2C, illustrated is the pre-expansion joint 240 illustrated in FIG. 2A after subjecting it to an activation fluid to expand the metal in the overlapping space 230, and thereby form an expanded metal joint 260 including residual unreacted expandable metal therein. In one embodiment, the expanded metal joint 260 includes at least 1% residual unreacted expandable metal therein. In yet another embodiment, the expanded metal joint 260 includes at least 3% residual unreacted expandable metal therein. In even yet another embodiment, the expanded metal joint 260 includes at least 10% residual unreacted expandable metal therein, and in certain embodiments at least 20% residual unreacted expandable metal therein.

Turning now to FIGS. 3A through 3C, depicted are various different manufacturing states for a junction 300 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 3A illustrates the junction 300 pre-expansion, FIG. 3B illustrates the junction 300 post-expansion, and FIG. 3C illustrates the junction 300 post-expansion and containing residual unreacted expandable metal therein. The junction 300 of FIGS. 3A through 3C is similar in many respects to the junction 200 of FIGS. 2A through 2C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 300 differs, for the most part, from the junction 200, in that the junction 300 is a multi-step junction. Accordingly, the junction 300 includes multiple pre-expansion metal joints 340, as well as multiple expanded metal joints 350, and/or multiple expanded metal joints 360 with residual unreacted expandable metal therein. In the illustrated embodiment of FIGS. 3A through 3C, the junction 300 includes three steps, each of which is parallel with the length (L₁). In yet other embodiments, the junction 300 might include only two steps, or alternatively more than three steps, depending on the design of the junction. Moreover, one or more of the steps could be angled relative to the length (L₁).

Turning now to FIGS. 4A through 4C, depicted are various different manufacturing states for a junction 400 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 4A illustrates the junction 400 pre-expansion, FIG. 4B illustrates the junction 400 post-expansion, and FIG. 4C illustrates the junction 400 post-expansion and containing residual unreacted expandable metal therein. The junction 400 of FIGS. 4A through 4C is similar in many respects to the junction 300 of FIGS. 3A through 3C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 400 differs, for the most part, from the junction 300, in that the junction 400 includes an elastomeric sealing member 470 positioned in the overlapping space 230. For example, in the illustrated embodiment, the elastomeric sealing member 470 is positioned between ones of the multiple pre-expansion metal joints 440, multiple expanded metal joints 450, or multiple expanded metal joints 460 containing residual unreacted expandable metal therein, depending on the illustrated view. When the pre-expansion metal joint 440 expands into the expanded metal joint 450, the elastomeric sealing member 470 may be compressed. Accordingly, the junction 400 is both an anchoring and sealing junction.

Turning now to FIGS. 5A through 5C, depicted are various different manufacturing states for a junction 500 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 5A illustrates the junction 500 pre-expansion, FIG. 5B illustrates the junction 500 post-expansion, and FIG. 5C illustrates the junction 500 post-expansion and containing residual unreacted expandable metal therein. The junction 500 of FIGS. 5A through 5C is similar in many respects to the junction 200 of FIGS. 2A through 2C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 500 differs, for the most part, from the junction 200, in that the junction 500 includes an angled overlapping space 530 having the pre-expansion metal joint 540, expanded metal joint 550, or expanded metal joint 560 containing residual unreacted expandable metal therein, depending on the illustrated view.

Turning now to FIGS. 6A through 6C, depicted are various different manufacturing states for a junction 600 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 6A illustrates the junction 600 pre-expansion, FIG. 6B illustrates the junction 600 post-expansion, and FIG. 6C illustrates the junction 600 post-expansion and containing residual unreacted expandable metal therein. The junction 600 of FIGS. 6A through 6C is similar in many respects to the junction 500 of FIGS. 5A through 5C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 600 differs, for the most part, from the junction 500, in that the junction 600 includes an elastomeric sealing member 670 positioned in the overlapping space 530. For example, in the illustrated embodiment, the elastomeric sealing member 670 is positioned between ones of the multiple pre-expansion metal joints 640, multiple expanded metal joints 650, or multiple expanded metal joints 660 containing residual unreacted expandable metal therein, depending on the illustrated view. When the pre-expansion metal joint 640 expands into the expanded metal joint 650, the elastomeric sealing member 670 may be compressed. Accordingly, the junction 600 is both an anchoring and sealing junction.

Turning now to FIGS. 7A through 7C, depicted are various different manufacturing states for a junction 700 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 7A illustrates the junction 700 pre-expansion, FIG. 7B illustrates the junction 700 post-expansion, and FIG. 7C illustrates the junction 700 post-expansion and containing residual unreacted expandable metal therein. The junction 700 of FIGS. 7A through 7C is similar in many respects to the junction 300 of FIGS. 3A through 3C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 700 differs, for the most part, from the junction 300, in that the junction 700 includes parallel and angled portions.

Turning now to FIGS. 8A through 8C, depicted are various different manufacturing states for a junction 800 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 8A illustrates the junction 800 pre-expansion, FIG. 8B illustrates the junction 800 post-expansion, and FIG. 8C illustrates the junction 800 post-expansion and containing residual unreacted expandable metal therein. The junction 800 of FIGS. 8A through 8C is similar in many respects to the junction 700 of FIGS. 7A through 7C.

Accordingly, the junction 800 is both an anchoring and sealing junction.

Turning now to FIGS. 9A through 9C, depicted are various different manufacturing states for a junction 900 designed, manufactured and operated according to an alternative embodiment of the disclosure. FIG. 9A illustrates the junction 900 pre-expansion, FIG. 9B illustrates the junction 900 post-expansion, and FIG. 9C illustrates the junction 900 post-expansion and containing residual unreacted expandable metal therein. The junction 900 of FIGS. 9A through 9C is similar in certain respects to the junction 200 of FIGS. 2A through 2C. Accordingly, like reference numbers have been used to illustrate similar, if not identical, features. The junction 900 differs, for the most part, from the junction 200, in that the junction 900 In accordance with one embodiment, such as that shown, the locking feature 910 is a snap ring, for example used to support the axial loads. In this embodiment, the pre-expansion metal joint 240, expanded metal joint 250, and expanded metal joint 260 containing residual unreacted expandable metal therein, may only be necessary to seal the junction 900. In another embodiment, the locking feature 910 could be an internal slip, or any other known locking feature.

FIG. 9E illustrates the first member 210 and the second member 220 wherein they are partially overlapping one another. As shown, the locking feature 910 is in the radially retracted state. For instance, a chamfered edge of the first member 210 could engage with an angled or chamfered edge of the locking feature 910 to urge the locking feature 910 to the radially retracted state. Accordingly, the first member 210 and the second member 220 are still allowed to slide relative to one another.

FIG. 9F illustrated the first member 210 and the second member 220 in their final axial state. At this stage, the locking feature 910 is axially aligned with a locking feature profile 920 in the first member 210, and thus the locking feature 910 is allowed to radially expand into the locking feature profile 920 and axially fix the first member 210 relative to the second member 220. Thus, the first member 210 and the second member 220 are no longer allowed to slide relative to one another, and thus form the overlapping space 230.

FIG. 9G illustrates the junction 900 of FIG. 9F, after the pre-expansion joint 240 has been subjected to an activation fluid to expand the metal in the overlapping space 230, and thereby form an expanded metal joint 250.

The interval control valve 1700 illustrated in FIG. 17 additionally includes a sliding sleeve 1730 positioned within the tubular 1710. In the illustrated embodiment, the sliding sleeve 1730 is configured to move between a closed position (e.g., as shown) closing a fluid path between the one or more opening 1720 and an interior of the tubular housing 1710, and an open position (e.g., not shown) opening the fluid path between the one or more openings 1720 and the interior of the tubular housing 1710.

The interval control valve 1700, in at least one embodiment, further includes a tubular 1740 overlapping with the sliding sleeve 1730. As discussed in great detail above, the overlap of the tubular 1740 and the sliding sleeve 1730 defines an overlapping space (e.g., not shown). In at least one embodiment, the sliding sleeve 1730 and the tubular 1740 comprise different materials. For example, the sliding sleeve 1730 could be steel, whereas the tubular 1740 could be a carbide material, such as tungsten carbide. In this embodiment, the tubular 1740 could be an abrasion resistant tip, such as a carbide (e.g., tungsten carbide) abrasion resistant tip.

In the illustrated embodiment, the sliding sleeve 1730 has a first wall thickness (t₁) proximate the overlapping space and the tubular 1740 has a second wall thickness (t₂) proximate the overlapping space.

Thus, in accordance with the embodiment shown, the sliding sleeve 1730 and the tubular 1740 are thin walled structures.

In the illustrated embodiment, the sliding sleeve 1730 has a first inside diameter (d₁) proximate the overlapping space and the tubular 1740 has a second inside diameter (d₂) proximate the overlapping space. In the illustrated embodiment, the overlapping space (and thus the resulting expanded metal joint) is positioned proximate an end of the sliding sleeve 1730 or tubular 1740. In accordance with at least one embodiment, the overlapping space (and thus the resulting expanded metal joint) is positioned less than a distance (D_p) from the end of the sliding sleeve 1730 or tubular 1740. The distance (D_p), in one or more embodiments, is equal to or less than four times the first inside diameter (d₁). The distance (D_p), in one or more other embodiments, is equal to or less than two times the first inside diameter (d₁).

In the illustrated embodiment, the sliding sleeve 1730 and the tubular 1740 overlap by a distance (D_o).

In many embodiments, the pre-expansion metal joint is subjected to the activation fluid uphole, or at or above ground level.

In the illustrated embodiment, the expanded metal joint 1750 generally fills the overlapping space, as that term is defined above. In yet other embodiments, the expanded metal joint 1750 substantially fills the overlapping space, as that term is defined above, or in yet other embodiments, the expanded metal joint 1750 excessively fills the overlapping space, as that term is defined above.

Notwithstanding the foregoing, the expanded metal joint 1750 may have a variety of different volumes and remain within the scope of the disclosure.

In at least one embodiment, the multilateral junction 2300 employs a junction similar to the junction of FIGS. 9A through 9G, and thus includes a locking feature.

In one or more other embodiments, the single first bore 2330, the second bore 2340, and the third bore 2350 may each include one or more separate bores, and thus may each coupled to one or more separate tubulars. Accordingly, if any one of the single first bore 2330, the second bore 2340, and the third bore 2350 include multiple bores, each of the multiple bores could include the aforementioned expanded metal joints 2380. Furthermore, not all of the single first bore 2330, the second bore 2340, or the third bore 2350 need include the aforementioned expanded metal joints 2380.

It should also be noted that in certain other embodiments, the expanded metal joints 2380 may be located in other portions of the multilateral junction 2300. For instance, a seal stinger could be coupled at the end of the mainbore leg 2360. In this embodiment, the expanded metal joint 2380 may be used to couple the mainbore leg 2360 and the seal stinger. In another embodiment, a transition cross-over (e.g., D to round transition cross-over) could be coupled at the end of the lateral bore leg 2370. In this embodiment, the expanded metal joint 2380 may be used to couple the lateral bore leg 2370 to the transition cross-over.
