ABSTRACT:
A liner running system for placing a liner in a well bore comprises a latch sleeve connected to the liner and a running tool releasably attached to the latch sleeve. The latch sleeve has a wall thickness substantially the same as the wall thickness of the liner, and the running tool has an outer diameter less than or equal to the inner diameter of the liner. The latch sleeve may be connected into the liner at any location along its length. The running tool is releasable from the latch sleeve via hydraulic actuation or mechanical actuation. Optionally, a swivel may be connected to the liner. The swivel has a wall thickness substantially the same as the wall thickness of the liner. The method for lowering the liner into the well bore via the liner running system comprises rotating the liner, pushing the liner, pulling the liner, or a combination thereof.
