Hydrocarbons are commonly produced from wells that penetrate a subterranean formation, either beneath dry land or beneath a body of water. Within such subterranean formations, massive quantities of fluids and gases, including hydrocarbons, may be present at very high pressures. Therefore, throughout the processes of drilling and completing the well, producing hydrocarbons from the subterranean formation, stimulating the subterranean formation to improve hydrocarbon production therefrom, and/or, ultimately, closing-in and abandoning the well, a variety of measures are employed to maintain control of the well.
Despite efforts to maintain control over a well through the process associated with that well, unforeseen circumstances, equipment failures, or other factors may lead to the loss of control of a well. Loss of well control may result in formation fluids being emitted from the well at uncontrolled flow rates and pressures, thereby posing serious environmental and safety hazards. As such, when control over a well is lost, it is necessary to, as expediently as possible, regain control thereof. Regaining control over a well may necessitate making a suitable connection to a well component in order to cease the uncontrolled escape of formation fluids.
Accordingly, there exists a need for an apparatus for use in regaining control over a well and method of using the same.

Not intending to be bound by theory, it is theorized that the capability of the diverter spool to disperse fluid pressure and/or fluid flow may be improved where the flow area of the secondary flowbores 450 approaches or exceeds the flow area of the primary flowbore 430.
In an embodiment, the body 420 and the side outlets 440 may be configured such that at least about 75%, alternatively, at least about 80%, alternatively, at least about 85%, alternatively, at least about 90%, alternatively, at least about 95% of the volume of the fluid that enters the diverter spool 400 may expelled therefrom via the side outlets 440 while the average fluid velocity within the secondary flowbores 450 is not more than about 125%, alternatively, not more than about 120%, alternatively, not more than about 115%, alternatively, not more than about 110%, alternatively, not more than about 105%, alternatively, not more than about 100%, of the average fluid velocity in the primary flowbore 430.

In an embodiment, the diverter spool 400 may be configurable, by altering one or more of the parameters disclosed herein, for use in wide-ranging circumstances. For example, the size of the flowbores (e.g., the primary flowbore 430 and/or the secondary flowbore 450), the angle at which the side outlets 440 intersect the body 420, the length of the side outlets 440, the angle of the connection assemblies 425 with respect to the body 420, the angle of the secondary connection assemblies 445 with respect to the side outlets 440, the pressure thresholds exhibited by the diverter spool 400, or combinations thereof may be varied to meet a particular circumstance.
One or more embodiments of a diverter spool (e.g., diverter spool 400) and a WCA (e.g., WCA 200) having been disclosed, also disclosed herein are one or more embodiments of methods of containing a well employing such a diverter spool and/or a well containment assembly. In an embodiment, such a well containment method may generally comprise the steps of preparing a well in need of containment for connection to a well containment assembly comprising a diverter spool, placing a WCA in proximity to the well such that at least a portion of the fluid escaping from the well the is directed into the WCA, connecting the WCA to the well, and suppressing fluid flow through at least a portion of the WCA.
In an embodiment, a well in need of containment may be prepared for connection to a WCA 200 by removing damaged components and providing a connection with which the WCA 200 may be mated. For example, where a component of a well has been damaged, has lost integrity, is defective, or otherwise fails to contain a fluid emitted from a well, it may be necessary to remove all or a portion of the inoperable or damaged component. Examples of such components as may necessitate removal include, but are not limited to, a riser, a wellhead, a production tubing joint, a BOP stack, or combinations thereof. Referring again to the embodiment of
In an embodiment where the well to be contained is located beneath a body of water, such as body of water 120, at least a portion of the process of preparing the well for connection to the WCA 200 may be performed remotely via the operation of ROVs, lifting cranes, or other equipment conventionally employed to perform such tasks.
In the embodiment of
In an embodiment, the drilling sting 140 may comprise an obstructing device (e.g., a valve, “blank,” or “blind”) 143 configured to restrict and/or prevent the flow of well fluids upward through the flowbore 141 of the tubing string 140 during positioning of the WCA 200. In an embodiment, the tubing string 140 may also comprise a plurality of ports and/or windows 142 configured to disperse fluid pressure from the axial flowbore 141 of the tubing string 140, for example, positioned between a PCD 300 and the obstructing device 143.
In an embodiment, the WCA 200 may be brought into proximity with the wellhead 150 with all valves and/or the like within the WCA 200 (e.g., actuatable valves or devices of the PCDs 300 and/or the diverter spool) in an open configuration. For example, the WCA 200 may be configured such that the WCA 200 will allow any fluid that flows into the WCA 200 to be emitted therefrom via ports/windows 142 and/or side outlets 440.
In an embodiment, the WCA 200 may be positioned in proximity to the wellhead 150 such that at least a portion of the fluid stream 151 emitted from the well is directed into the WCA 200, for example, by coaxially aligning the lowermost portion of the flowbore 301 with the fluid stream 151 (approximately coaxial with wellhead 150). Alternatively, in an embodiment where a diverter spool like diverter spool 400 comprises the lowermost component of a WCA, the primary flowbore 430 of the diverter spool 400 may be similarly coaxially aligned with the fluid stream 151 (approximately coaxial with wellhead 150). Referring to
It is appreciated that, in an embodiment, the wellhead 150 or the well component to which the WCA 200 will be connected may deviate from a perfectly vertical orientation, particularly in cases where well components have been damaged. In such an embodiment, it may be advantageous to configure the diverter spool 400 (e.g., as disclosed herein) and/or other components of the WCA 200 to aid in connecting to the wellhead 150 and/or to allow for access to the diverter spool 400 and/or the WCA 200 following connection to the well.
In an embodiment, with the WCA 200 positioned in proximity to the wellhead 150, the WCA 200 and the wellhead 150 may be secured via a suitable connection. For example, in an embodiment where the lower portion of the WCA 200 and the wellhead 150 each comprise flanges, the flanges may be secured by a plurality of bolts, clamps, or the like. Suitable alternative connections may be appreciated by one of skill in the art viewing this disclose. Examples of such alternatives connections include but are not limited to collet connectors or hydraulically controlled squeeze lock contraptions.
In an embodiment, with the WCA 200 secured to the wellhead 150, the fluid flow through and/or out of the WCA 200 may be curtailed and/or ceased. In an embodiment, the fluid emitted from the side outlets 440 of the diverter spool 400 may be ceased by actuating a valve (e.g., valves 460) attached to each of the side outlets. In an embodiment, the valve 460 may be connected to the side outlets 440 before the WCA 200 is lowered into the body of water 120, alternatively, the valve 460 may be connected to the side outlets 440 after the WCA 200 has been positioned with respect to the wellhead 150 and secured thereto. In an embodiment, the valves may be actuated via the operation of an ROV like ROV 500. In another embodiment, the fluid flowing via the flowbore 301 extending through the PCDs 300 may be ceased by actuating one or more of the PCDS 300. The choice of which fluid movement should be ceased and the sequence thereof may be determined based upon objectives and considerations as will be apparent to one of skill in the art viewing this disclosure.
A WCA and/or a diverter spool of the type disclosed herein may be advantageously employed in the performance of well containment processes as described herein. For example, a diverter spool such as diverter spool 400 may allow fluid to efficiently be dispersed while a WCA like WCA 200 is connected to a well component (e.g., wellhead 150 as disclosed herein). As disclosed herein, the massive pressures and volumes of fluid escaping from an uncontrolled well make it difficult to connect another component thereto and, thereby, difficult to bring the well under control. That is, if the fluid and/or the pressure is not dissipated, the pressure and or fluid may cause it to be nearly impossible to position a WCA with respect to an open well in that the stream of fluid may tend to eject objects from its path. A diverter spool as disclosed herein allows such fluid and/or fluid pressure to be efficiently dissipated, thereby making connection of the WCA 200 possible.
Further, the diverter spool 400 may also improve the ability to make a connection to the WCA 200 by moving at least a portion of the fluids away from the immediate proximity of the connection. Often, and particularly in subsea embodiments, connecting a WCA to an open well is further complicated by the fact that, if the escaping fluid is not allowed to be removed from the site of the connection, visibility may be decreased to the point that it is difficult, if not impossible for work to progress. In an embodiment, the diverter spool 400 allows at least a portion of the fluid escaping an open well to be carried away from the immediate site of the connection and dissipated elsewhere (e.g., above the site of the connection between the WCA 200 and the wellhead 150).

At least one embodiment is disclosed and variations, combinations, and/or modifications of the embodiment(s) and/or features of the embodiment(s) made by a person having ordinary skill in the art are within the scope of the disclosure. Alternative embodiments that result from combining, integrating, and/or omitting features of the embodiment(s) are also within the scope of the disclosure. Where numerical ranges or limitations are expressly stated, such express ranges or limitations should be understood to include iterative ranges or limitations of like magnitude falling within the expressly stated ranges or limitations (e.g., from about 1 to about 10 includes, 2, 3, 4, etc.; greater than 0.10 includes 0.11, 0.12, 0.13, etc.). For example, whenever a numerical range with a lower limit, R1, and an upper limit, Ru, is disclosed, any number falling within the range is specifically disclosed. In particular, the following numbers within the range are specifically disclosed: R=R1+k*(Ru−R1), wherein k is a variable ranging from 1 percent to 100 percent with a 1 percent increment, i.e., k is 1 percent, 2 percent, 3 percent, 4 percent, 5 percent, . . . , 50 percent, 51 percent, 52 percent, . . . , 95 percent, 96 percent, 97 percent, 98 percent, 99 percent, or 100 percent. Moreover, any numerical range defined by two R numbers as defined in the above is also specifically disclosed. Use of the term “optionally” with respect to any element of a claim means that the element is required, or alternatively, the element is not required, both alternatives being within the scope of the claim. Use of broader terms such as comprises, includes, and having should be understood to provide support for narrower terms such as consisting of, consisting essentially of, and comprised substantially of. Accordingly, the scope of protection is not limited by the description set out above but is defined by the claims that follow, that scope including all equivalents of the subject matter of the claims. Each and every claim is incorporated as further disclosure into the specification and the claims are embodiment(s) of the present invention.
