Abstract
A system for expanding a tubular member. In some embodiments, the system includes an expansion assembly disposed in sealingly engagement within the tubular member, a shoe assembly releasably coupled within the tubular member, and a chamber disposed therebetween. The expansion assembly has a flowbore and a openable port. The shoe assembly includes a flowbore extending therethrough, the flowbore in fluid communication with the flowbore of the expansion assembly and having a valveable passage. When the valveable passage is closed, the port is adapted to open, whereby the chamber is fluidicly coupled to the flowbore of the expansion assembly. When the valveable passage is open, the port remains closed, whereby the chamber is fluidicly isolated from the flowbore of the expansion assembly.
Description
- Not applicable.
- Not applicable.
- The present disclosure relates generally to an apparatus for expanding tubular members. More particularly, the present disclosure relates to a recoverable shoe assembly for a liner expansion system.
- To form a wellbore using some conventional systems and methods, a drill string initially forms a borehole, and a casing is then installed at the top portion of the borehole. Next, the drill string extends the length of the borehole below the casing. An expandable tubular member, or liner, is then suspended by an expansion assembly within the casing. The expansion assembly includes a tubular member supporting an expansion cone. The expandable liner is then radially expanded by the expansion cone into engagement with the casing to extend the lining of the borehole.
- The expandable liner includes a shoe at its lower end and a launcher assembly disposed therebetween. The shoe has a valveable passage extending therethrough. The launcher assembly has a lower portion connected to the shoe, an upper portion connected to the expandable liner, and a tapered portion extending therebetween. The inner diameter of the lower portion is greater than that of the upper portion, enabling the launcher assembly to receive the expansion cone therein. The expansion cone sealingly engages the lower portion of the launcher assembly. Thus, a chamber is formed within the launcher assembly between the expansion cone and the shoe. The shoe passage, when open or closed, enables or prevents, respectively, fluid communication between the launcher assembly chamber and the annulus between the borehole and expandable liner. The expandable liner is supported by the tubular support member via engagement between the tapered portion of the launcher assembly and the expansion cone.
- Prior to expansion of the expandable liner, a ball, or dart, is delivered via pressurized fluid injected from the surface through the tubular support member, expansion cone, and launcher assembly to seat on the shoe passage, thereby closing the passage and preventing subsequent flow of the pressurized fluid therethrough. Continued injection of pressurized fluid causes pressurized fluid to fill the launcher assembly chamber. When the pressure of fluid contained within the launcher assembly chamber reaches a sufficient level, the fluid pressure causes the expansion cone disposed within the launcher assembly to displace upward within the launcher assembly into the expandable liner. As the expansion cone travels upward within the liner, engagement between the cone and the liner causes radial expansion of the liner.
- After the liner has been expanded into engagement with the casing, the expansion cone is removed from the borehole. To again extend the length of the borehole below the now-expanded liner, the shoe coupled to the lower end of the expanded liner must first be removed. The drill string is inserted within the liner, and the shoe is drilled out. Once removed, successive expandable tubulars may be installed and the borehole extended in the same manner until the wellbore reaches the desired depth.
- As the shoe is drilled out, pieces of it fall into the borehole. Occasionally, these pieces block the borehole, thereby preventing further extension of the borehole. Consequently, it becomes necessary to divert the borehole around the blockage, or abandon the wellbore and form another. Given the significant cost associated with both, there is a need for a recoverable shoe that enables installation of an expandable liner.
- A system including a recoverable shoe assembly for expanding a tubular member, or liner, is disclosed. In some embodiments, the expansion system includes an expansion assembly disposed in sealingly engagement within the tubular member, a shoe assembly releasably coupled within the tubular member, and a chamber disposed therebetween. The expansion assembly has a flowbore and a openable port. The shoe assembly includes a flowbore extending therethrough, the flowbore in fluid communication with the flowbore of the expansion assembly and having a valveable passage. When the valveable passage is closed, the port is adapted to open, whereby the chamber is fluidicly coupled to the flowbore of the expansion assembly. When the valveable passage is open, the port remains closed, whereby the chamber is fluidicly isolated from the flowbore of the expansion assembly.
- In other embodiments, the expansion system includes a tubular launcher having a plurality of circumferentially-spaced slots extending therethrough and a shoe assembly sealingly disposed therein. The shoe assembly has a flowbore extending therethrough, the flowbore having a valveable passage, and a plurality of members, each member radially moveable between an extended position and a retracted position. When in the extended position, each member engages one of the slots, whereby rotation of the shoe assembly relative to the tubular launcher is prevented and whereby axial translation of the shoe assembly relative to the tubular member is prevented in at least a first direction. When in the retracted position, each member is disengaged from the slots.
- Some methods for expanding a tubular member, or liner, in a wellbore include releasably coupling a shoe assembly within the tubular member, delivering pressurized fluid through a flowbore of the shoe assembly, the flowbore having a valveable passage, closing the valveable passage, whereby the pressurized fluid is diverted into a chamber disposed between the shoe assembly and an expansion cone, translating the expansion cone relative to the tubular member under hydraulic pressure, whereby the expansion cone radially expands the tubular member, disengaging the shoe assembly from the tubular member, and retrieving the shoe assembly from the wellbore.
- Thus, embodiments described herein comprise a combination of features and characteristics intended to address various shortcomings associated with certain prior devices. The various characteristics described above, as well as other features, will be readily apparent to those skilled in the art upon reading the following detailed description of the preferred embodiments, and by referring to the accompanying drawings.

- Referring now to
FIG. 1 , there is shown a liner expansion system including a recoverable shoe assembly in accordance with the principles disclosed herein.Liner expansion system 100 includes anexpansion assembly 105 coupled to arecoverable shoe assembly 110 installed within an expandable tubular member, or liner, 115.Expansion assembly 105 is hydraulically actuatable to displace upward withinexpandable liner 115 relative toshoe assembly 110 to radially expandliner 115.Shoe assembly 110 enables coupling of a pressurized fluid source (not shown) toexpansion assembly 105, whereby pressurized fluid is delivered throughexpansion assembly 105 to achamber 120 withinexpandable liner 115. The pressurized fluid withinchamber 120 causes upward displacement ofexpansion assembly 105 withinexpandable liner 115, whereby engagement betweenexpansion assembly 105 andliner 115 causes radial expansion ofliner 115.Shoe assembly 110 also sealingly engages thelower end 125 ofexpandable liner 115 to enable pressurization ofchamber 120. -
Expansion assembly 105 includes anexpansion cone 130, anexpansion mandrel 135 inserted therethrough, and atubular support member 140 coupled to theupper end 145 ofexpansion mandrel 135.Tubular support member 140 has aflowbore 150 extending therethrough, and, in this embodiment, is coupled toupper end 145 ofexpansion mandrel 135 viamating threads 155 formed on the inner and outer surfaces oftubular support member 140 andexpansion mandrel 135, respectively.Flowbore 150 oftubular support member 140 is in fluid communication with, or is fluidicly coupled to, the pressurized fluid source. -
Expansion mandrel 135 has aflowbore 160 extending therethrough. Whenexpansion mandrel 135 is coupled totubular support member 140, as shown inFIG. 1 , flowbore 160 is in fluid communication withflowbore 150 oftubular support member 140.Expansion mandrel 135 further includes one ormore ports 165 extending therethrough. A rupture or burstdisc 170 is seated within eachport 165. Eachrupture disc 170 is configured to prevent fluid flow throughport 165 when the pressure of fluid passing throughflowbore 160 is less than a preselected level and to burst or rupture when the fluid pressure exceeds the preselected level to allow fluid flow throughport 165. - Referring next to
FIG. 2 ,expansion mandrel 135 further includes generally radially extending upper andlower surfaces expansion assembly 105 is installed withinexpandable liner 115, as shown inFIG. 1 ,expansion cone 130 is supported byupper surface 137 ofexpansion mandrel 135. Referring still toFIG. 2 ,expansion mandrel 135 further includes a plurality of circumferentially-spacedsplines 230 extending fromlower surface 139. Eachspline 230 has alength 235 extending substantially parallel to a longitudinal centerline 228 ofexpansion mandrel 135 and awidth 240 that extends substantially circumferentially or azimuthally relative to centerline 225. Thus, splines 230 may be referred to as longitudinally or axially disposed splines. Arecess 245 is formed between each pair ofadjacent splines 230.Splines 230 are configured to matingly engage and interlock with another set of splines extending fromrecoverable shoe assembly 110, as will be described. -
Expansion cone 130 has athroughbore 175 configured to receiveexpansion mandrel 135 therethrough.Expansion cone 130 further includes an upper portion orneck 180, a lower portion orbase 185, and atapered portion 190 extending therebetween.Neck 180 ofexpansion cone 130 has anouter surface 195 defined by a diameter that enables insertion ofneck 180 into an unexpanded portion 200 (FIG. 1 ) ofliner 115 whenexpansion assembly 105 is installed withinexpandable liner 115, as shown inFIG. 1 .Base 185 has anouter surface 205 defined by a diameter that enables radial expansion ofliner 115 to the desired inner diameter and/or wall thickness.Tapered portion 190 ofexpansion cone 130 has anouter surface 210 configured to engage an inner surface 215 (FIG. 1 ) ofliner 115 to enableexpansion cone 130 to radially expandliner 115. In this embodiment,outer surface 210 is substantially linear and offset relative to a longitudinal centerline 225 ofexpansion cone 130 by an angle 220. - Referring again to
FIG. 1 ,expandable liner 115 includes alauncher assembly 250 at itslower end 125. In this embodiment,launcher assembly 250 includes twoseparate components weld 270. In other embodiments, however,launcher assembly 250 may be a single-piece component. - Turning to
FIG. 3 ,launcher assembly 250 includes anupper launcher 260 and alower launcher 265.Upper launcher 260 is tubular, having alower portion 275, anupper portion 280, and atapered portion 285 extending therebetween.Upper portion 280 has aninner surface 290 defined by a diameter corresponding to the inner diameter ofexpandable liner 115 prior to radial expansion.Lower portion 275 has aninner surface 295 defined by a diameter that enablesexpansion cone 130 andshoe assembly 110 to be inserted therein, as shown inFIG. 1 . As previously described,inner surface 215 of taperedportion 285 engagesouter surface 210 of taperedportion 190 ofexpansion cone 130 during expansion ofliner 115. -
Lower launcher 265 is also tubular, having anouter surface 315 and aninner surface 305 defined by a diameter that enablesexpansion cone 130 andshoe assembly 110 to be inserted therethrough. In this embodiment, the diameter ofinner surface 305 is substantially constant along the length oflower launcher 265. Moreover, in some embodiments, the diameter ofinner surface 305 is slightly less than the inner diameter oflower portion 275 ofupper launcher 260 to promote sealing betweenlower launcher 265 andshoe assembly 110. -
Lower launcher 265 further includes a plurality of circumferentially-spacedslots 310 extending therethrough. Eachslot 310 has aheight 335 and awidth 340. Further, eachslot 310 is bounded by alower surface 320 and anupper surface 325. In this embodiment,lower surface 320 is generally planar and extends normally relative to alongitudinal centerline 345 oflauncher assembly 250.Upper surface 325 is generally planar as well but offset relative tocenterline 345 by anangle 330. The angular orientation ofupper surface 325 is such thatheight 335 ofslot 310 increases through the wall oflower launcher 265 fromouter surface 315 towardinner surface 305. - Returning to
FIG. 1 ,recoverable shoe assembly 110 includes acollet assembly 350 and aguide mandrel 355 inserted therein. Whenshoe assembly 110 is installed withinlauncher assembly 250 as shown,collet assembly 350 is coupled betweenexpansion mandrel 135 ofexpansion assembly 105 andlower launcher 265 oflauncher assembly 250. Turning toFIG. 4 ,collet assembly 350 has alongitudinal centerline 400. The right half of this figure, defined bycenterline 400, is shown in cross-section while the left half of this figure is not.Collet assembly 350 further includes aseal mandrel 360 having a generallycylindrical body 362 with anupper end 365 and alower end 370.Seal mandrel 360 further includes anouter surface 375 and aninner surface 377 extending between upper and lower ends 365, 370. Agroove 380 is formed inouter surface 375 to receive asealing element 385, such as but not limited to an O-ring. Whencollet assembly 350 is installed withinlauncher assembly 250 ofliner expansion system 100, as shown inFIG. 1 , sealingelement 385 prevents the leakage of pressurized fluid fromchamber 120 betweenlauncher assembly 250 andcollet assembly 350 during radial expansion ofliner 115. - Referring still to
FIG. 4 ,collet assembly 350 further includes a plurality of circumferentially-spacedsplines 390 extending fromupper end 365 ofseal mandrel 360. Eachspline 390 has alength 395 extending substantially parallel tolongitudinal centerline 400 ofcollet assembly 350 and awidth 405 that extends substantially circumferentially or azimuthally aboutcenterline 400. Thus, splines 390 may also be referred to as longitudinally or axially disposed splines. Arecess 410 is formed between each pair ofadjacent splines 390. -
Splines 390 are configured to matingly engage and interlock withsplines 230 ofexpansion mandrel 135, as illustrated byFIG. 5 . To enable such engagement,length 395 andwidth 405 of eachspline 390 is selected to enablespline 390 to be received within arecess 245 betweenadjacent splines 230 ofexpansion mandrel 135. Similarly,length 235 andwidth 240 of eachspline 230 ofexpansion mandrel 135 is selected to enable eachspline 230 to be received in arecess 410 betweenadjacent splines 390 ofcollet assembly 350. When the interlockingsplines expansion assembly 105 andshoe assembly 110 to prevent relative rotation therebetween. - Referring again to
FIG. 4 ,collet assembly 350 further includes a plurality of circumferentially-spacedcollets 415 extending fromlower end 370 ofseal mandrel 360.Collets 415 are configured to enable releasable coupling ofcollet assembly 350 withinlauncher assembly 250. Eachcollet 415 is flexible to enable limited bending relative to sealmandrel 360. Eachcollet 415 has aninner surface 530 defined by a diameter greater than a diameter ofinner surface 377 ofseal mandrel 360. Hence, ashoulder 534 is formed incollet assembly 350 at the transition betweenseal mandrel 360 andcollets 415. Eachcollet 415 also has afoot 420 that is insertable within and releasable from a slot 310 (FIG. 3 ) oflower launcher 265. Thus, whencollet assembly 350 is inserted withinlower launcher 265, eachcollet 415 can bend radially inward to enable translation ofcollet assembly 350 withinlower launcher 265 untilfoot 420 engages, or snaps into, aslot 310, as illustrated byFIG. 5 . Subsequently, eachcollet 415 can again bend radially inward to enable disengagement offoot 420 fromslot 310. - Further, each
foot 420 ofcollets 415 has awidth 427 that is slightly less than width 340 (FIG. 3 ) of theslot 310. Eachfoot 420 is bounded by alower surface 425 configured to engage lower surface 320 (FIG. 3 ) ofslot 310 and anupper surface 430 configured to slidingly engage upper surface 325 (FIG. 3 ) ofslot 310. In this embodiment,lower surface 425, likelower surface 320, is generally planar and extends normally relative tolongitudinal centerline 400 ofcollet assembly 350.Upper surface 430, likeupper surface 325 ofslot 310, is generally planar as well but offset relative tocenterline 400 by an angle 435 that is substantially equal toangle 330 ofupper surface 325. - When installed within
lower launcher 265, as shown inFIG. 5 ,collet assembly 350 is prevented from rotating relative to lowerlauncher 265 due to engagement betweenfeet 420 ofcollets 415 with bounding surfaces ofslots 310 oflower launcher 265. Further,collet assembly 350 is prevented from downward axial translation, or translation away fromexpansion mandrel 135, relative tolower launcher 265 due to engagement betweenlower surfaces 425 offeet 420 andlower surfaces 320 ofslots 310. However,collet assembly 350 may translate in the opposite direction, or axially upward, relative tolower launcher 265 when sufficient upward tension is applied tocollet assembly 350. This relative movement is enabled by the sliding engagement between tapered,upper surfaces 430 offeet 420 and similarly tapered,upper surfaces 325 ofslots 310. Thus, under sufficient upward tension,collet assembly 350 disengageslower launcher 265. - Referring next to
FIG. 6 , guidemandrel 355 is tubular in nature, having aflowbore 440 extending therethrough between aninlet 445 and anoutlet 450.Flowbore 440 includes anupper portion 455, alower portion 460, and atapered portion 465 extending therebetween.Lower portion 460 is bounded by aninner surface 470 ofguide mandrel 355 defined by a diameter that is smaller than a diameter of aninner surface 475 ofguide mandrel 355 boundingupper portion 455. As such, taperedportion 465 forms aball seat 480. -
Guide mandrel 355 further includes a generallycylindrical body 485 extending between afishing neck 490 and aguide nose 495.Fishing neck 490 is configured to be insertable withinflowbore 160 ofexpansion mandrel 135 ofexpansion assembly 105 whenshoe assembly 110 is installed withinexpandable liner 115 in engagement withexpansion assembly 105, as shown inFIG. 1 . When so inserted, flowbore 440 ofguide mandrel 355 is in fluid communication with, or fluidicly coupled to, flowbore 160 ofexpansion mandrel 135, andfishing neck 490 sealingly engages the inner surface ofexpansion mandrel 135 andcollet assembly 350 via sealing elements 492 (FIG. 1 ). Consequently, pressurized fluid injected from the surface passes fromflowbore 160 ofexpansion mandrel 135 throughflowbore 440 ofguide mandrel 355, exitingguide mandrel 355 throughoutlet 450. To disrupt or prevent fluid flow throughguide mandrel 355, a ball (not shown) may be introduced to the pressurized fluid at the surface and delivered throughupper portion 455 offlowbore 440 toball seat 480, whereby fluid flow throughguide mandrel 355 is prevented. -
Guide nose 495 has anupper end 510 connected tobody 485, alower end 515 whereinoutlet 450 offlowbore 440 is disposed, and anouter surface 520 extending therebetween. The diameter ofguide nose 495 atupper end 510 is greater than that ofguide nose 495 atlower end 515. As such, the diameter ofouter surface 520 increases fromlower end 515 ofguide nose 495 toupper end 510. Tapering ofouter surface 520 in this manner enables run-in ofliner expansion system 100 into a wellbore containing fluid. In particular, taperedsurface 520 is less resistive to fluid flow than some surfaces having other shapes or orientations. - The outer diameter of
guide nose 495 atupper end 510 is greater than that ofcylindrical body 485 coupled thereto. Hence, ashoulder 525 is formed inguide mandrel 355 at the transition betweenguide nose 495 andbody 485. The outer diameter ofguide nose 495 atshoulder 525 is less than that ofinner surfaces upper launchers guide mandrel 355 to be pulled fromliner 115 via wireline, or similar device, as will be described below. Moreover, the outer diameter ofguide nose 495 atshoulder 525 is greater than the diameter of inner surface 377 (FIG. 4 ) ofseal mandrel 360. As such,shoulder 525 enables retrieval ofcollet assembly 350 withguide mandrel 355 when the latter is pulled fromliner 115. When a tension load is applied to guidemandrel 355 via wireline, or similar device, guidemandrel 355 initially displaces axially upward relative tocollet assembly 350 untilshoulder 525 ofguide mandrel 355 engagesshoulder 534 ofcollet assembly 350. Additional tension to guidemandrel 355 causes guidemandrel 355 to displacecollet assembly 350 axially upward such thatcollets 415disengage slots 310 oflower launcher 265. Once disengaged,collet assembly 350 is supported byguide mandrel 355 asguide mandrel 355 andcollet assembly 350 are pulled from the wellbore. -
Body 485 ofguide mandrel 355 includeslower portion 535 connected to guidenose 495 and anupper portion 540 extending betweenlower portion 535 andfishing neck 490.Lower portion 535 has anouter surface 565 defined by a diameter that is smaller than that ofinner surface 530 ofcollets 415 to provide a clearance 570 (FIG. 1 ) therebetween.Clearance 570 betweencollets 415 and guidemandrel 355 enablescollets 415 to bend radially inward to engage and disengageslots 310 oflower launcher 265, as described above. -
Upper portion 540 ofbody 485 has anouter surface 545 defined by a diameter that is slightly less that the diameter of an inner surface 550 (FIG. 1 ) ofseal mandrel 360.Upper portion 540 includes agroove 555 formed inouter surface 545 to receive asealing element 560, such as but not limited to an O-ring. Whenguide mandrel 355 is installed withincollet assembly 350, as shown inFIG. 1 , sealingelement 555 sealing engagesinner surface 550 ofseal mandrel 360 to prevent leakage of pressurized fluid fromchamber 120 betweenguide mandrel 355 andcollet assembly 350 during expansion ofliner 115. - In some embodiments, guide
mandrel 355 may include either or both of anexternal fishing profile 500 and aninternal fishing profile 505, each configured to enable retrieval ofguide mandrel 355 and other components coupled thereto, such ascollet assembly 350, from a wellbore in whichliner expansion system 100 is installed. In this embodiment, guidemandrel 355 includes both.External fishing profile 500 is an annular lip formed about the free end offishing neck 490.Internal fishing profile 505 is a shoulder formed alonginner surface 455 bounding flowbore 440proximate inlet 445. To retrieveguide mandrel 355, a wireline, or similar device, is lowered from the surface into the wellbore to enclose aboutlip 500 or to engageshoulder 505. Once connected thereto, the wireline may then be used to pullguide mandrel 355 andcollet assembly 350 from the wellbore. - Returning to
FIG. 1 , to assembleliner expansion system 100,expansion assembly 105 is installed withinexpandable liner 115.Expansion mandrel 135 is inserted throughbore 175 ofexpansion cone 130, andexpansion cone 130, withexpansion mandrel 135 disposed therein, is inserted throughlower launcher 265 intoupper launcher 260 oflauncher assembly 250. Next,recoverable shoe assembly 110 is then coupled toexpansion assembly 105 andexpandable liner 115.Guide mandrel 355 is inserted throughcollet assembly 350 such thatfishing neck 490 ofguide mandrel 355 extends intoflowbore 160 ofexpansion mandrel 135 andshoulder 525 ofguide mandrel 355 abutsshoulder 534 ofcollet assembly 350.Collet assembly 350, withguide mandrel 355 disposed therein, is inserted intolower launcher 265 to engagecollets 415 ofcollet assembly 350 withinslots 310 oflower launcher 265.Guide mandrel 355 is coupled in position withincollet assembly 350 with one or more shear pins 357 (FIG. 1 ) extending betweenguide mandrel 355 andlauncher assembly 250. The assembled components are then run-in to a wellbore to the desired depth. - Next,
tubular support member 140 is coupled to the installedliner expansion system 100 to provide pressurized fluid tosystem 100 for expansion ofliner 115.Tubular support member 140 is inserted downhole to couple withexpansion mandrel 135. In this embodiment,tubular support member 140 threadingly engagesexpansion mandrel 135 viamating threads 155. As described above, whencollet assembly 350 is installed withinlower launcher 265, the engagement offeet 420 ofcollets 415 ofcollet assembly 350 withinslots 310 oflower launcher 265 prevents relative rotation of these components. Further, whencollet assembly 350 is coupled toexpansion cone 130 ofexpansion assembly 105 via interlockingsplines collet assembly 350 cannot rotate relative toexpansion cone 130. Thus, once installed,expansion cone 130 andexpansion mandrel 135 disposed therein are prevented from rotating relative toliner 115. This enables rotational coupling oftubular support member 140 toexpansion mandrel 135. - During operation of
liner expansion system 100, pressurized fluid is delivered from the pressurized fluid source at the surface throughflowbore 150 oftubular support member 140, flowbore 160 ofexpansion mandrel 135, and flowbore 440 ofguide mandrel 355 to exitsystem 100 viaoutlet 450. To initiate radial expansion ofliner 115, a ball (not shown) is introduced to the pressurized fluid at the surface. The pressurized fluid carries the ball along the same path to seat onball seat 480, whereby the flow of pressurized fluid fromguide mandrel 355 throughoutlet 450 is interrupted. - Due to the blockage of fluid flow through
flowbore 440 ofguide mandrel 355, the pressure of fluid inflowbore 160 ofexpansion mandrel 135 increases until it reaches the preselected level at whichdiscs 170 rupture. Afterdiscs 170 rupture, pressurized fluid passes fromflowbore 160 throughports 165 ofexpansion mandrel 135 intochamber 120. When the pressure of fluid withinchamber 120 reaches a sufficient level, pressure acting onexpansion cone 130 causescone 130 to displace axially upward, whereby engagement betweeninner surface 215 ofliner 115 andouter surface 190 ofexpansion cone 130 causes radial expansion ofliner 115. At the same time,collets 415 ofcollet assembly 350 resist the axial pressure load of the fluid acting onseal mandrel 360 and provide support to sealmandrel 360. - When radial expansion of
liner 115 is complete, the flow of pressurized fluid tosystem 100 is discontinued, andexpansion assembly 105 is pulled from the wellbore. Next, a wireline, or similar device, is lowered into the wellbore to engage either external orinternal fishing profiles guide mandrel 355. A tension load is then applied to guidemandrel 355, causing severance of shear pins 357 coupled betweenguide mandrel 355 andlauncher assembly 250. Afterpins 357 are sheared,guide mandrel 355 displaces axially upward relative tocollet assembly 350 untilshoulder 525 ofguide mandrel 355 engagesshoulder 534 ofcollet assembly 350. Continued tension to guidemandrel 355 and thereforecollet assembly 350 causescollets 415 to disengageslots 310 oflower launcher 265. Once disengaged,guide mandrel 355 andcollet assembly 350 supported thereon are pulled from expandedliner 115. Thus,shoe assembly 110 is recovered, eliminating the need to drill out the shoe, as is typically done in conventional liner expansion systems, and the associated problems. - In the above-described embodiment,
flexible collets 415 enable releasable coupling ofrecoverable shoe assembly 110 tolauncher assembly 250. One of ordinary skill in the art will readily appreciate that releasable coupling of theserespective assemblies -
FIGS. 7A and 7B depicts a liner expansion system with another recoverable shoe assembly in accordance with the principles disclosed herein installed within a lower launcher. As in the liner expansion system described above,lower launcher 615 is also tubular, having anouter surface 620 and aninner surface 625 defined by a diameter than enablesexpansion cone 130 andshoe assembly 600 to be inserted therethrough.Lower launcher 615 further includes a plurality of circumferentially-spacedslots 630 extending therethrough. -
Recoverable shoe assembly 600 includes aseal mandrel 605, guidemandrel 355 disposed therein, and a plurality of circumferentially-spacedlugs 610 that are extendable to engageslots 630 oflower launcher 615, as shown inFIG. 7A , and retractable to disengageslots 630, as shown inFIG. 7B .Seal mandrel 605 has a generallycylindrical body 635 with an upper end (not shown) and alower end 640. Although not shown,seal mandrel 605, likeseal mandrel 360 described above, includes a plurality ofsplines 390 extending from its upper end.Splines 390, as previously described, are configured to matingly engage and interlock withsplines 230 ofexpansion mandrel 135. When the interlockingsplines expansion assembly 105 andshoe assembly 600 to prevent relative rotation therebetween.Seal mandrel 605 further includes a plurality of circumferentially-spacedslots 645 extending therethrough. Eachslot 645 is configured to receive alug 610, as shown. -
Lugs 610 are actuatable to extend to engageslots 630 oflower launcher 615, as shown inFIG. 7A , and to retract to disengageslots 630, as shown inFIG. 7B . In some embodiments, lugs 610 are spring-loaded and biased toward their retracted orientation. Eachlug 610 includes abody 650 and ahead 655 coupled thereto.Body 650 is configured to be received withinslots seal mandrel 605, respectively.Head 655 has a cross-section that is larger than that ofslot 645, thereby limiting radial extension oflug 610 withinslots Head 655 engagesguide mandrel 355 whenguide mandrel 355 is inserted withinseal mandrel 605, as shown. In some embodiments, one or more of theradial extending surfaces 660 ofhead 655 are angled or cropped to enableguide mandrel 355 to be inserted betweenlugs 610. The angular nature ofsurface 660 provides sliding engagement withupper portion 540 ofguide mandrel 355 asguide mandrel 355 is inserted withinlugs 610 andseal mandrel 605. - During assembly, lugs 610 are installed within
seal mandrel 605, and sealmandrel 605 is inserted withinlower launcher 615 such thatslots Guide mandrel 355 is then installed withinseal mandrel 605. Asguide mandrel 335 is inserted withinseal mandrel 605, contact betweenupper portion 540 ofguide mandrel 355 andangled surfaces 660 oflugs 610 causes lugs 610 to extend intoslots 630 oflower launcher 615 and enablesguide mandrel 355 to be received betweenlugs 610. When lugs 610 engageslots 630,seal mandrel 605 is prevented from rotating and from translating axially relative tolower launcher 615. As previously described, this enables coupling of tubular support member 140 (FIG. 1 ) to expansion mandrel 135 (FIG. 1 ). - When it is desired to remove
shoe assembly 600 fromlower launcher 615, for instance, when expansion of a liner coupled tolower launcher 615 is complete, a wireline, or similar device, is coupled to guidemandrel 355, and guidemandrel 355 is pulled upward relative to lowerlauncher 615, as described above. Whenupper portion 540 ofguide mandrel 355 translates axially abovelugs 610, lugs 610 retract radially inward towardlower portion 535 ofguide mandrel 355 and disengageslots 630 inlower launcher 615, as shown inFIG. 7B . Once retracted,seal mandrel 605 withlugs 610 supported therein is translatable and rotatable relative to lowerlauncher 615. Further upward translation ofguide mandrel 355 due to tension from the wireline causes engagement betweenlugs 610 andshoulder 525 ofguide mandrel 355. Engagement betweenshoulder 525 and lugs 610 enablesseal mandrel 605 and lugs 610 to be supported byguide mandrel 355 asshoe assembly 600 is pulled fromlower launcher 615 and the expanded liner coupled thereto. - While various embodiments have been shown and described, modifications thereof can be made by one skilled in the art without departing from the spirit and teachings herein. The embodiments herein are exemplary only, and are not limiting. Many variations and modifications of the apparatus disclosed herein are possible and within the scope of the invention. Accordingly, the scope of protection is not limited by the description set out above, but is only limited by the claims which follow, that scope including all equivalents of the subject matter of the claims.
