- This disclosure relates generally to the construction, maintenance, and repair of wellbore tubular strings to facilitate hydrocarbon production or downhole fluid injection.
- When an opening is formed in the sidewalls of an existing wellbore casing, whether through damage to the casing or because of an intentional perforation of the casing, it is often necessary to repair the opening in the existing wellbore casing. Conventional methods of repairing such openings can create unacceptable restrictions in the wellbore or fail to provide the necessary performance requirements once they are installed.
- The principles of the present disclosure are directed to overcoming one or more of the limitations of the existing apparatus and processes for repairing openings in existing casing.
- For a more detailed description of the embodiments of the present disclosure, reference will now be made to the accompanying drawings, wherein:
-
FIG. 1 is a schematic, partial section view of one embodiment of a system for repairing casing shown in an initial position; -
FIG. 2 is the system ofFIG. 1 shown in an expanded position; -
FIG. 3 illustrates the wellbore as repaired by the system ofFIG. 1 ; -
FIG. 4 is a schematic, partial section view of an alternative embodiment of a system for repairing casing shown in an initial position; and -
FIG. 5 is the system ofFIG. 4 shown in an expanded position. - In the drawings and description that follow, like parts are typically marked throughout the specification and drawings with the same reference numerals. The drawing figures are not necessarily to scale. Certain features of the invention may be shown exaggerated in scale or in somewhat schematic form and some details of conventional elements may not be shown in the interest of clarity and conciseness. The present disclosure is susceptible to 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 invention, and is not intended to limit the invention to that illustrated and described herein. It is to be fully recognized that the different teachings of the embodiments discussed below may be employed separately or in any suitable combination to produce desired results.
- Unless otherwise specified, any use of any form of the terms “connect”, “engage”, “couple”, “attach”, or any other 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. In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . ”.

- Referring initially to
FIG. 1 ,casing repair system 10 comprises anexpandable tubular 12 coupled to ahousing 14 by areleasable connection 16.Housing 14 has anupper end 18 that is coupled to afluid conduit 20 that supplies pressurized fluid tosystem 10.Fluid conduit 20 may be a drill pipe, coiled tubing, wireline-run pump, or other system operable to supportsystem 10 within thewellbore casing 22 and provide pressurized fluid to the system. Expandable tubular 12 includes sealingmembers 36 that are operable to sealingly engagewellbore casing 22 after the tubular is expanded. -
Patch system 10 also comprisesexpansion assembly 21 comprisingpiston 24,expansion cone 26, andmandrel 28. Piston 24 is disposed within and sealingly engaged withhousing 14. Piston 24 is coupled tocone 26 bymandrel 28.Cone 26 is disposed partially within expandable tubular 12 and is operable to radially expand tubular 12 as the cone moves longitudinally therethrough. Cone 26 has apressure relief port 30 that allows fluid communication across the cone.Housing 14 also includes apressure relief port 32 that provides fluid communication across the housing andmandrel stop 34 that limits the movement ofmandrel 28 relative to the housing. - In operation,
system 10 is lowered intowellbore casing 22 until sealingmembers 36 are located on either said ofcasing penetrations 38. Once in the desired location,fluid conduit 20 supplies pressurized fluid to theupper end 18 ofhousing 14. The pressurized fluid applied topiston 24 causes the piston,mandrel 28, andexpansion cone 26 to move longitudinally relative tohousing 14. This motion causesexpansion cone 26 to move longitudinally through expandable tubular 12, which causes the tubular to be radially expanded. - As
piston 24 moves throughhousing 14, fluid withinpressure chamber 40, defined by the piston andexpansion cone 26, is expelled throughrelief port 32 intoannulus 42.Pressure relief port 30 allows fluid trapped below expandable tubular 12 to flow intopressure chamber 40 and out into annulus 44 throughrelief port 32. Asexpansion cone 26 moves longitudinally through and radially expands expandable tubular 12, sealingmembers 36 are also radially expanded into sealing engagement withwellbore casing 22. - Referring now to
FIG. 2 ,expansion cone 26 has fully expanded expandable tubular 12. The motion ofexpansion cone 26 is stopped whenpiston 24 reachesmandrel stop 34. Sealingmembers 36 are engaged withwellbore casing 22, hydraulically isolatingcasing penetrations 38 from the wellbore. Once, expandable tubular 12 has been fully expandedreleasable connection 16 can be disconnected, such as by rotatinghousing 14 relative to tubular 12. Disconnectingreleasable connection 16 allows expandable tubular 12 to separate fromhousing 14.Housing 14, along withpiston 24,expansion cone 26, andmandrel 28 can be retrieved from the wellbore, leaving expandable tubular in place, as is shown inFIG. 3 . - Referring now to
FIGS. 4 and 5 ,casing repair system 50 comprises anexpandable tubular 52 coupled to ahousing 54 by areleasable connection 56.Housing 54 has anupper end 58 that is coupled to afluid conduit 60 that supplies pressurized fluid tosystem 50.System 50 also comprises anexpansion assembly 62 including apiston 64,mandrel 66,connection latch 68, andexpansion cone 70.Connection latch 68 is operable to engagereleasable connection 56 and disengage expandable tubular 52 fromhousing 54 once the connection latch is disposed adjacent to the releasable connection, as is shown inFIG. 5 . - In operation,
casing repair system 50 is positioned inwellbore 72 using drillpipe, coiled tubing, wireline, or other conveyance devices as are know in the art.Casing repair system 50 may be positioned inwellbore 72 so thatseal members 74 are disposed on either side ofcasing penetrations 76. Once insystem 50 is in position, pressurized fluid is supplied tohousing 54 byconduit 60. The pressurized fluid can be supplied by pumps at the surface or by a pump run into the wellbore. - The pressurized fluid in
housing 54 causespiston 64,mandrel 66,latch 68, andexpansion cone 70 to move longitudinally relative tohousing 54. This motion causesexpansion cone 70 to move longitudinally through and radially expand expandable tubular 52. Aspiston 64 moves throughhousing 54, fluid withinpressure chamber 78, defined by the piston andexpansion cone 70, is expelled throughrelief port 80 intoannulus 82.Pressure relief port 84 allows fluid trapped below expandable tubular 52 to flow intopressure chamber 78 and out intoannulus 82 throughrelief port 80. Asexpansion cone 70 moves longitudinally through and radially expands expandable tubular 52, sealingmembers 74 are also radially expanded into sealing engagement with wellbore casing 86, as is shown inFIG. 5 . - Referring still to
FIG. 5 ,expansion cone 70 has fully expanded expandable tubular 52. The motion ofexpansion assembly 62 is stopped whenpiston 64 reaches mandrelstop 88. In certain embodiments, the engagement ofconnection latch 68 andreleasable connection 54 may alternatively stop the motion ofexpansion assembly 62.Sealing members 74 are engaged with wellbore casing 86, hydraulically isolatingcasing penetrations 76 from the wellbore.Connection latch 68 engagesreleasable connection 56 and disconnects expandable tubular 52 fromhousing 54.Housing 54, along withexpansion assembly 62 can be retrieved from the wellbore, leaving expandable tubular 52 in place. - While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and description. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the disclosure to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present disclosure.
