Abstract
The present invention provides apparatus and methods for completing a wellbore using expandable tubulars. In one aspect, the invention includes a tubular member with an expandable portion at a lower end constructed and arranged to be expanded into contact with a previously expanded liner. At an upper end of the tubular is a polish bore receptacle permitting the tubular to be tied back to the surface of the well with production tubing. In another aspect, the invention provides a method of completing a well comprising expanding a liner top into a cased wellbore to hang the liner and, thereafter running a tubular member into the wellbore.
Claims25
A method of completing a well, comprising:
- placing a first tubular in a wellbore proximate a lower end of a cased portion of the wellbore, leaving an overlapping portion therebetween;
- expanding the first tubular in the overlapped portion, wherein the first tubular is operatively fixed in the cased portion;
- placing a second tubular in the wellbore proximate the first tubular, the second tubular having a polished bore portion and an expandable portion;
- expanding the expandable portion of the second tubular, whereby the second tubular is operatively fixed in the first tubular;
- and
- forming a fluid path to the surface of the well.
A method for completing a wellbore, the wellbore having a lined portion, comprising:
- running a first tubular into the wellbore, the first tubular having an expandable portion;
- suspending the first tubular at a desired location within the wellbore, wherein at least the expandable portion of the first tubular is in an overlapping relationship with the lined portion of the wellbore;
- expanding the expandable portion of the first tubular, wherein the expanded portion of the first tubular is sealingly engaged to the lined portion of the wellbore;
- running a second tubular into the wellbore, the second tubular having a polished bore receptacle and an expandable portion;
- suspending the second tubular at a desired location within the first tubular, wherein at least the expandable portion of the second tubular is in an overlapping relationship with the expanded portion of the first tubular;
- expanding the expandable portion of the second tubular, wherein the expanded portion of the second tubular is sealingly engaged to the expanded portion of the first tubular;
- and
- mating a lower portion of a third tubular into the polished bore receptacle of the second tubular, wherein the lower portion of the third tubular is configured to sealingly land into the polished bore receptacle of the second tubular.
A tubular system for completing a wellbore, the wellbore having a lined portion, the tubular system comprising:
- a first tubular, the first tubular having an expandable portion, wherein the expandable portion is sealingly expandable against the lined portion of the wellbore by a radial outward force applied on an inner wall thereof;
- and
- a second tubular, the second tubular comprising:
- a polished bore receptacle, wherein the polished bore receptacle is configured to sealingly receive a third tubular;
- and
- an expandable portion, wherein the expandable portion is sealingly expandable against the expanded portion of the first tubular by a radial outward force applied on an inner wall thereof.
