BORE LINER

摘要

A method of lining a drilled bore comprises running an expandable first tubular (18) into a bore and locating part portion of the first tubular in an unlined section of the bore and another portion of the first tubular (14) overlapping a portion of an existing second tubular. The first tubular is secured (24) relative to the second tubular while retaining the provision of fluid outlets to permit displacement of fluid from an annulus between the first tubular and the bore wall. An expansion device (23) is then run through the first tubular to expand the first tubular to a larger diameter. Cement is then circulated into the annulus between the expanded first tubular and the bore wall. The fluid outlets are then closed.
