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.
Claims14
A method of completing a well comprising:
- running a liner into a cased wellbore;
- locating an upper potion of the liner proximate a lower portion of the cased wellbore, leaving an overlapping area therebetween;
- expanding the liner in the overlapping area whereby an outer surface of the liner is placed into contact with an inner surface of the cased welibore, whereby the liner is bearingly fixed within the cased wellbore;
- running a length of tubular into the well, a lower portion of the tubular being expandable and an upper portion having a polish bore receptacle formed therein;
- expanding the lower portion of the tubular into the expanded liner whereby the tubular is fixed within the liner;
- and
- running a tubular string into the well to tie into the polish bore receptacle, thereby forming a fluid path to a surface of the well.
A method of completing a well comprising:
- running a length of tubular into a wellbore, a bottom portion of the tubular being expandable and an upper portion having a polish bore receptacle formed therein;
- and
- expanding the lower portion of the tubular into a liner whereby the tubular is fixed within the liner and the polish bore receptacle is available to receive another tubular.
A tubular member for use in a wellbore, comprising:
- a first portion, the first portion expandable by a radial outward force applied from an interior thereof;
- and
- a second portion there above having a polish bore receptacle formed therein.
