Claims
- 1. An apparatus for expanding a tubular liner, comprising:
a support member defining a first fluid passage; an expansion mandrel coupled to the support member including an outer expansion surface and defining a second fluid passage; a tubular liner coupled to the expansion mandrel; and a shoe coupled to the tubular liner defining a third fluid passage; wherein the first, second and third fluid passages are operably coupled; and wherein the interface between the tubular liner and the expansion mandrel is not fluid tight.
- 2. The apparatus of claim 1, wherein the support member further includes a shock absorber.
- 3. The apparatus of claim 1, wherein the support member includes one or more sealing members adapted to prevent foreign material from entering an interior region of the tubular liner.
- 4. The apparatus of claim 1, wherein the support member includes one or more stabilizers.
- 5. The apparatus of claim 1, wherein the expansion mandrel is expandable.
- 6. The apparatus of claim 1, wherein the tubular liner is fabricated from materials selected from the group consisting of Oilfield Country Tubular Goods, automotive grade steel, plastic and chromium steel.
- 7. The apparatus of claim 1, wherein the tubular liner has inner and outer diameters ranging from about 0.75 to 47 inches and 1.05 to 48 inches, respectively.
- 8. The apparatus of claim 1, wherein the tubular liner has a plastic yield point ranging from about 40,000 to 135,000 psi.
- 9. The apparatus of claim 1, wherein the tubular liner includes one or more sealing members at an end portion.
- 10. The apparatus of claim 1, wherein the tubular liner includes one or more pressure relief holes at an end portion.
- 11. The apparatus of claim 1, wherein the tubular liner includes a catching member at an end portion for slowing down movement of the expansion mandrel.
- 12. The apparatus of claim 1, wherein the shoe further defines an fluid conduit coupled to the third fluid passage, the fluid conduit adapted to receive a plug for blocking the fluid conduit.
- 13. The apparatus of claim 1, wherein the support member comprises coiled tubing.
- 14. The apparatus of claim 1, wherein the shoe includes one or more exhaust passages coupled to the third fluid passage for injecting fluidic material outside of the shoe.
- 15. The apparatus of claim 1, further comprising at least one wiper plug removably coupled to the expansion mandrel.
- 16. The apparatus of claim 15, wherein the wiper plug defines a fourth passage operably coupled to the second fluid passage.
- 17. The apparatus of claim 1, wherein at least a portion of the expansion mandrel and shoe are drillable.
- 18. The apparatus of claim 1, the wall thickness of the tubular liner in an area adjacent to the expansion mandrel is less than the wall thickness of the tubular liner in an area that is not adjacent to the expansion mandrel.
- 19. The apparatus of claim 1, wherein third fluid passage defined by the shoe comprises one or more radial passages defined by the shoe.
- 20. The apparatus of claim 1, further comprising a packer coupled to the shoe.
- 21. The apparatus of claim 1, wherein the wall thickness of a portion of the tubular liner above the expansion surface of the expansion mandrel is greater than the wall thickness of a portion of the tubular liner below the expansion surface of the expansion mandrel.
- 22. An apparatus for expanding a tubular liner, comprising:
a support member defining a first fluid passage; an expansion mandrel coupled to the support member including an outer expansion surface and defining a second fluid passage; a tubular liner coupled to the expansion mandrel; a shoe coupled to the tubular liner defining a third fluid passage; and a packer coupled to the shoe; wherein the first, second and third fluid passages are operably coupled.
- 23. An apparatus for expanding a tubular liner, comprising:
a support member defining a first fluid passage; an expansion mandrel coupled to the support member including an outer expansion surface and defining a second fluid passage; a tubular liner coupled to the expansion mandrel; and a shoe coupled to the tubular liner defining a third fluid passage; wherein the first, second and third fluid passages are operably coupled; and wherein the third fluid passage defined by the shoe comprises one or more radial passages.
- 24. An apparatus for expanding a tubular liner, comprising:
a support member defining a first fluid passage; an expansion mandrel coupled to the support member including an outer expansion surface and defining a second fluid passage; a tubular liner coupled to the expansion mandrel; and a shoe coupled to the tubular liner defining a third fluid passage; wherein the first, second and third fluid passages are operably coupled; and wherein the wall thickness of a portion of the tubular liner above the expansion surface of the expansion mandrel is greater than a wall thickness of a portion of the tubular liner below the expansion surface of the expansion mandrel.
