Abstract

Embodiments of the present invention generally provide methods and apparatus for forming a tubular-lined wellbore which does not decrease in diameter with increasing depth or length. In one aspect, a portion of a second casing (220) is expanded into a portion of a first casing (204) having a larger inner diameter than the remaining portion of the first casing string. In another aspect, the portion of the second casing is expanded into a portion of the first casing having a compressible member (505) therearound. In another aspect, a lined lateral wellbore may be constructed by forming a lateral wellbore extending from a main wellbore lined with casing. A diameter of at least a portion of the lateral wellbore may be expanded. An expandable tubular element may be run into lateral wellbore and expanded to have an inner diameter equal to or larger than an inner diameter of the main wellbore casing. Embodiments provide a fluid path around casing before sealing the casing within a wellbore or within a well casing, even after the casing has been hung within the wellbore or from the well casing.

Claims (29)

1. A method of forming a cased well, comprising:
lowering a first tubular having an earth removal member operatively attached to its lower end into a formation to form a first wellbore having a first length, at least a portion of the first tubular comprising casing;
locating at least a portion of a second tubular within the first tubular, at least a portion of the second tubular comprising casing; and expanding at least the portion of the second tubular so that at least the portion of the second tubular has an inner diameter at least as large as a smallest inner diameter portion of the first tubular.
2. The method of claim 1, wherein the second tubular has an earth removal member operatively attached to its lower end.
3. The method of claim 1, wherein locating at least a portion of the second tubular within the first tubular comprises lowering the second tubular into the formation to form a second wellbore of a second length.
4. The method of claim 3, wherein the first wellbore is a main wellbore and the second wellbore is a lateral wellbore.
5. The method of claim 4, wherein expanding at least the portion of the second tubular comprises expanding a portion of the lateral wellbore extending into the main wellbore.
6. The method of claim 4, wherein an inner diameter of the lateral wellbore is greater than or equal to an inner diameter of the main wellbore.
7. The method of claim 3, wherein the second tubular is expanded along its entire length to have an inner diameter at least as large as the smallest inner diameter portion of the first tubular.
8. The method of claim 1, wherein a portion of the first tubular has an enlarged inner diameter and at least the portion of the second tubular located within the first tubular is expanded into the enlarged inner diameter portion of the first tubular.
9. The method of claim 8, wherein the enlarged inner diameter portion is at a lower end of the first tubular.
10. The method of claim 9, wherein at least one compressible member is disposed within the enlarged inner diameter portion of the first tubular.
11. The method of claim 10, wherein expanding at least the portion of the second tubular comprises compressing at least a portion of the at least one compressible member.
12. The method of claim 11, wherein compressing at least the portion of the at least one compressible member comprises moving a plurality of webs of the at least one compressible member through at least one void area.
13. The method of claim 8, wherein the enlarged inner diameter portion is an undercut cementing shoe.
14. The method of claim 3, wherein a drillable portion is disposed within the enlarged inner diameter portion which is constructed and arranged to become dislodged from the first tubular when lowering the second tubular into the formation to form a second wellbore of a second length.
15. The method of claim 1, wherein the first tubular includes at least one compressible member disposed therearound.
16. The method of claim 15, further comprising compressing the at least one compressible member when expanding at least the portion of the second tubular.
17. The method of claim 16, wherein the at least one compressible member is compressed by expansion until at least the portion of the second tubular being expanded has an inner diameter at least as large as a smallest inner diameter portion of the first tubular.
18. The method of claim 15, further comprising introducing a physically alterable bonding material into an annulus between the first tubular and the formation therearound prior to expanding at least the portion of the second tubular.
19. The method of claim 18, wherein a portion of the second tubular surrounding the first tubular is expanded when expanding at least the portion of the second tubular.
20. The method of claim 15, wherein the compressible member is located at a lower end of the first tubular.
21. The method of claim 3, wherein expanding at least the portion of the second tubular comprises:
expanding at least the portion of the second tubular into gripping engagement with the first tubular to hang the second tubular within the well;
leaving a fluid path between the first tubular and the second tubular after expanding at least the portion of the first tubular;
flowing a fluid through the fluid path; and closing the fluid path.
22. The method of claim 21, wherein closing the fluid path provides a seal between the first and second tubulars.
23. The method of claim 21, wherein at least a portion of the first tubular is profiled and the fluid path comprises one or more fluid bypass areas formed in the profiled portion of the first tubular.
24. The method of claim 21, wherein the fluid path comprises one or more openings in the first tubular to allow the fluid to flow into an annulus between the first and second tubulars.
25. The method of claim 21, wherein the fluid is a physically alterable bonding material.
26. The method of claim 21, further comprising expanding a lower end of the second tubular further radially than a remaining portion of the second tubular.
27. The method of claim 26, further comprising lowering at least a portion of a third tubular into the second tubular and expanding at least the portion of the third tuublar into gripping engagement with the second tubular while leaving a fluid path between the second and third tubular.
28. A method of forming a lined lateral wellbore comprising:
forming a lateral wellbore extending from a main wellbore, wherein a diameter of the lateral wellbore is larger than an inner diameter of casing lining the main wellbore;
running an expandable tubular element, through the casing lining the main wellbore, into the lateral wellbore; and expanding the tubular element within the lateral wellbore, such that the expanded tubular element has an outer diameter larger than the drift diameter of the casing lining the main wellbore.
29. A method of forming a cased well, comprising:
lowering a first casing having an earth removal member operatively attached to its lower end into a formation to form a wellbore of a first depth;
expanding at least a portion of the first casing into gripping engagement with the wellbore to hang the first casing within the wellbore;
leaving a fluid path between the first casing and the wellbore after expanding at least the portion of the first casing;
flowing a fluid through the fluid path; and closing the fluid path.
