Expandable tubulars
The present invention provides apparatus and methods for completing a wellbore using expandable tubulars. Particularly, the invention relates to a system of completing a wellbore through the expansion of tubulars. More particularly, embodiments of the present invention relate to the concurrent expansion of a first and second tubular, wherein the first tubular contains a polished bore receptacle configured to sealingly receive a portion of the second tubular thereby providing a sealable connection therebetween.
1. A method of completing a well comprising:
running a first tubular into a wellbore, wherein the wellbore comprises a cased portion;
suspending the first tubular at a selected depth within the cased portion;
running a second tubular into the wellbore, the second tubular having a forming member proximate a lower end thereof;
forming a portion of the first tubular with the forming member, the portion configured to sealingly receive an outer diameter of the second tubular; and
positioning the second tubular into the formed portion of the first tubular.
2. The method of claim 1 , further including sealing an overlapping portion between the first tubular and the second tubular.
3. The method of claim 1 , further including anchoring the second tubular in the first tubular.
4. The method of claim 1 , wherein the forming member is an expansion cone.
5. The method of claim 1 , further including removing the second tubular from the formed portion of the first tubular.
6. The method of claim 5 , further including running a third tubular into the wellbore.
7. The method of claim 6 , further including forming a second portion of the first tubular, the second portion is configured to sealingly receive an outer diameter of the third tubular.
8. The method of claim 7 , further including positioning the third tubular into the second formed portion of the first tubular.
9. The method of claim 1 , wherein an inner diameter of the second tubular is substantially equal to an inner diameter of the first tubular.
10. A tubular assembly for forming an anchor and/or seal receiving surface in a downhole tubular, the tubular assembly comprising:
a tubular member;
a cone member disposed on the tubular member proximate a lower end thereof, the cone member constructed and arranged to radially expand the tubular to form the anchor and/or seal receiving surface in the downhole tubular; and
a seal member disposed on the tubular member.
11. The tubular assembly of claim 10 , further including an anchor member to secure the tubular assembly in the downhole tubular.
12. The tubular assembly of claim 10 , wherein the upper portion of the tubular is configured to receive a second cone member of a substantially identical tubular.
13. The tubular assembly of claim 12 , wherein the substantially identical tubular is dimensionally similar to the first tubular assembly.
14. The tubular assembly of claim 12 , wherein the configuration of the tubular to receive a second tubular comprises a flare or taper.
15. The tubular assembly of claim 10 , wherein a hanging member is used to hang a tubular to a portion of casing.
16. The tubular assembly of claim 15 , wherein the hanging member is a slip mechanism or an expandable hanger.
17. The tubular assembly of claim 10 , wherein the seal receiving surface comprises a polished bore receptacle.
18. The tubular assembly of claim 10 , wherein the cone member comprises a radius.
