Abstract: A latch assembly, and methods of using the latch assembly, for use with a bottom hole assembly (BHA) and a tubular, are provided. In one embodiment, the latch assembly is disposable within the tubular, configured to be rotationally and axially coupled to the tubular. In one aspect of the embodiment, latch assembly is configured to be released from the tubular by applying a tensile force to the latch assembly. The latch the latch assembly may comprise: one or more sleds disposed within one or more respective slots formed along at least a portion of a locking mandrel; and one or more retractable axial drag blocks configured to engage a matching axial profile disposed in the tubular, wherein each axial drag block is coupled to the respective sled with one or more biasing members; and the locking mandrel actuatable between a first position and a second position and preventing retraction of the axial drag blocks when actuated to the second position. The latch assembly may also comprise a drag block body having a bore therethorugh; and one or more retractable torsional drag blocks configured to engage a matching torsional profile disposed in the tubular, wherein each torsional drag block is coupled to the drag block body with a biasing member.

Abstract: The present invention relates methods and apparatus for lining a wellbore. In one aspect, a drilling assembly having an earth removal member and a wellbore lining conduit is manipulated to advance into the earth. The drilling assembly includes a first fluid flow path and a second fluid flow path. Fluid is flowed through the first fluid flow path, and at least a portion of which may return through the second fluid flow path. In one embodiment, the drilling assembly is provided with a third fluid flow path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.
