摘要:
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.
