Definitions
- This disclosure relates generally to methods and apparatus for expanding a tubular member in a wellbore. More specifically, this disclosure relates to expanding a tubular member using an adjustable expansion cone.
- Wellbore tubular members such as casings or liners
- processes can be expanded in the wellbore using a variety of known processes. These processes often utilize expansion cones that are shaped to radially expand the tubular as the cone moved axially through the tubular.
- Many conventional expansion cones have a fixed outer diameter that is larger than the outer diameter of tubular member before expansion. The size of the fixed diameter expansion cone necessitates that, before expansion begins, the cone is contained within an enlarged section of the tubular, known as a launcher, or disposed outside of the tubular being expanded.
- the launcher or the expansion cone itself, is thus the component of the tool string having the largest outer diameter and is therefore a major factor in determining the operating envelope of the system. For example, if an expandable tubular is needed at a location in the wellbore below a restriction, the size of the launcher or cone will limit the systems that can be used. Fixed diameter cones are also susceptible to getting stuck in the unexpanded tubular should the expansion process fail or an unexpected restriction be encountered.
- Adjustable expansion cones have been used to overcome some of the limitations of fixed diameter cones by providing a mechanism for varying the outer diameter of the cone.
- Adjustable expansion cones generally include a plurality of segments that are “assembled” downhole into a cone capable of expanding a tubular member.
- Adjustable cones are available in a variety of styles and configurations but, like conventional fixed diameter cones, suffer from certain performance limitations and are generally more mechanically complex than fixed diameter cones.

Description
- This application claims priority to U.S. Patent Application Ser. No. 61/680,487, titled Hybrid Expansion Cone, which was filed Aug. 7, 2012. This priority application is hereby incorporated by reference in its entirety into the present application, to the extent that it is not inconsistent with the present application.
- This disclosure relates generally to methods and apparatus for expanding a tubular member in a wellbore. More specifically, this disclosure relates to expanding a tubular member using an adjustable expansion cone.
- Wellbore tubular members, such as casings or liners, can be expanded in the wellbore using a variety of known processes. These processes often utilize expansion cones that are shaped to radially expand the tubular as the cone moved axially through the tubular. Many conventional expansion cones have a fixed outer diameter that is larger than the outer diameter of tubular member before expansion. The size of the fixed diameter expansion cone necessitates that, before expansion begins, the cone is contained within an enlarged section of the tubular, known as a launcher, or disposed outside of the tubular being expanded.
- The launcher, or the expansion cone itself, is thus the component of the tool string having the largest outer diameter and is therefore a major factor in determining the operating envelope of the system. For example, if an expandable tubular is needed at a location in the wellbore below a restriction, the size of the launcher or cone will limit the systems that can be used. Fixed diameter cones are also susceptible to getting stuck in the unexpanded tubular should the expansion process fail or an unexpected restriction be encountered.
- Adjustable expansion cones have been used to overcome some of the limitations of fixed diameter cones by providing a mechanism for varying the outer diameter of the cone. Adjustable expansion cones generally include a plurality of segments that are “assembled” downhole into a cone capable of expanding a tubular member. Adjustable cones are available in a variety of styles and configurations but, like conventional fixed diameter cones, suffer from certain performance limitations and are generally more mechanically complex than fixed diameter cones.
- Thus, there is a continuing need in the art for methods and apparatus for adjustable expansion cones that overcome these and other limitations of the prior art.
- An expansion cone comprising a cone body having a first expansion surface with a diameter that increases from a leading edge to a first expansion diameter. A resilient sleeve disposed on an actuation mandrel that is coupled to the cone body. Movement of the actuation mandrel relative to the cone body moves an outer surface of the resilient sleeve to a second expansion diameter that is greater than the first expansion diameter.

- Referring initially to
FIG. 1 , ahybrid expansion cone 10 includes asolid cone body 12, aresilient sleeve 14, and anactuation mandrel 16. Thesolid cone body 12 includes anexpansion surface 18 with afirst end 20 having a leading edge diameter and asecond end 24 having a first expansion diameter. Theexpansion surface 18 has a diameter that increases from the leading edge diameter to the first expansion diameter in a linear or non-linear manner from thefirst end 20 to thesecond end 24. Thesolid cone body 12 also includes aconstant diameter portion 26 that extends from thesecond end 24 of the expansion surface and terminates in ashoulder 28. -
Actuation mandrel 16 includes amain body 30 having afirst end 32 that is slidably engaged with thesolid cone body 12. Anannular flange 34 projects radially outward from asecond end 36 of themain body 30. Theresilient sleeve 14 is disposed about themain body 30 of theactuation mandrel 16 between theannular flange 34 and theshoulder 28 ofsolid cone body 12 in a first position. Theresilient sleeve 14 may be constructed from any desirable resilient material including, but not limited to, polyurethane, rubber, polymers, and other materials. - Referring now to
FIG. 2 , during expansion operations, theactuation mandrel 16 is moved axially relative to thesolid cone body 12 so that theannular flange 34 moves closer to theshoulder 28. As theannular flange 34 moves closer to theshoulder 28, theresilient sleeve 14 is axially compressed, which causes the outer surface of theresilient sleeve 14 to move radially outward to a second position where the resilient sleeve forms a second expansion surface. - The
actuation mandrel 16 may be moved relative to thesolid cone body 12 by a variety of mechanisms. In certain embodiments, theactuation mandrel 16 may be coupled to a work string, or other component, that is operable to apply tension to pull theactuation mandrel 16 relative to thesolid cone body 12. In other embodiments, hydraulic pressure applied to theactuation mandrel 16 may generate the force needed to move theactuation mandrel 16 relative to thesolid cone body 12. In either embodiment described above, the force used to move theactuation mandrel 16 relative to thesolid cone body 12 may also be used to move thehybrid expansion cone 10 through a tubular member. - Referring now to
FIG. 3 , an alternativehybrid expansion cone 40 includes asolid cone body 42, aresilient sleeve 44, and anactuation mandrel 46 that directly radially expands theresilient sleeve 44. Thesolid cone body 42 includes afirst expansion surface 18 defined by afirst end 20 and asecond end 24. Thefirst expansion surface 18 has a diameter that increases from a leading edge diameter at thefirst end 20 to a first expansion diameter at thesecond end 24 in a linear or non-linear fashion. - The
resilient sleeve 44 may be coupled to thesolid cone body 42 at a location that is substantially adjacent to thesecond end 24 or may be spaced from thesecond end 24 by aconstant diameter portion 26. Theresilient sleeve 44 may be constructed from any desirable resilient material including, but not limited to, polyurethane, rubber, polymers, and other materials.Actuation mandrel 46 includes amain body 48 having a substantiallycylindrical portion 50 and anexpansion portion 52. In the unexpanded first position shown inFIG. 3 , thecylindrical portion 50 of the actuation mandrel is disposed under theresilient sleeve 44. - Referring now to
FIG. 4 , during expansion operations, theactuation mandrel 46 is moved axially relative to thesolid cone body 42 so that theexpansion portion 52 of theactuation mandrel 46 moves under and radially expands theresilient sleeve 44 to a second position. This radially outward movement of theresilient sleeve 44 creates asecond expansion surface 56. - The
actuation mandrel 46 may be moved relative to thesolid cone body 42 by a variety of mechanisms. In certain embodiments, theactuation mandrel 46 may be coupled to a work string, or other component, that is operable to apply tension to pull theactuation mandrel 16 relative to thesolid cone body 42. In other embodiments, hydraulic pressure applied to theactuation mandrel 46 may generate the force needed to move theactuation mandrel 46 relative to thesolid cone body 42. In either embodiment described above, the force used to move theactuation mandrel 46 relative to thesolid cone body 42 may also be used to move thehybrid expansion cone 40 through a tubular member. -
FIGS. 5A-5C illustrate the expansion of atubular member 60 using ahybrid expansion cone 10. Referring toFIG. 5A , ahybrid expansion cone 10 is coupled to an expansion system (not shown) and run into awellbore 62 with atubular member 60. Theresilient sleeve 14 is retracted so that the outside diameter of thehybrid expansion cone 10 is substantially the same as, or slightly larger than, the unexpanded outer diameter of thetubular member 60. This allows thehybrid expansion cone 10 and thetubular member 60 to be run through a wellbore restriction, such as a string of installedcasing 64. - Once the
tubular member 60 is positioned at a desired location in thewellbore 62, thehybrid expansion cone 10 is actuated and theresilient sleeve 14 moved to an expanded position. Thehybrid expansion cone 10 is then moved axially through thetubular member 60. As thehybrid expansion cone 10 moves through thetubular member 60, thesolid cone body 12 expands thetubular member 60 to a first expandedinner diameter 66 and theresilient sleeve 14 expands thetubular member 60 to a second expandedinner diameter 68. - As shown in
FIG. 5C , after thehybrid expansion cone 10 has fully expanded the entire length of thetubular member 60, thehybrid expansion cone 10 is returned to its retracted state with theresilient sleeve 14 refracted. Once theresilient sleeve 14 is retracted, thehybrid expansion cone 10 can pass freely through the installedcasing 64. - The
tubular member 60 is illustrated as being used in an open-hole clad application but is it understood that the methods illustrated and described herein are can also be used in other expandable applications. For example, a hybrid expansion cone could be used in a conventional casing expansion in its expanded state and the resilient sleeve only be refracted if the expansion cone should become stuck or need to otherwise pass through a restriction in the wellbore. A hybrid expansion cone could also be used in a pipe-in-pipe application where the resilient sleeve provides a slight over-expansion of the inner pipe to ensure close contact with the base pipe. - In other applications, a hybrid expansion cone could be used in an application where the resilient sleeve was only actuated to over-expand limited sections of the tubular, such as seal or anchor hanger sections, and the solid portion of the hybrid cone used for the substantial part of the expansion process. A hybrid expansion cone could also be used to expand a tubular into a well containing a tapered string or other casing strings where the inner diameter of the base casing may vary over the length of the casing. A hybrid expansion cone could also be used to create a larger inner diameter of the expanded casing at the upper end for use as a tie-back receptacle.
- 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.
