Abstract:
A system including a gripping tool and a rotary cutting tool may be used to grip a section of casing while cutting through a lower portion of the casing in a single trip. The gripping tool includes a mandrel with a flow bore extending therethrough, a slip actuator received on the mandrel, at least one slip corresponding to the slip actuator, a housing disposed around at least a proximal end of the mandrel, and a collet assembly disposed proximate the at least one slip. The rotary cutting tool is coupled to the mandrel. The gripping tool also includes a bearing assembly that enables the mandrel and the rotary cutting tool to rotate while the at least one slip is remains stationary engaging an interior wall of a casing. The system may include a hydraulic power section to help with setting the slips and removing the cut casing from the wellbore.

Claim (Index 19):
The method of  claim 16 , wherein the at least one piston comprises a plurality of pistons each disposed within and axially movable with respect to the housing, wherein each of the plurality of pistons is directly coupled to the mandrel and captured in a corresponding cylinder of the housing defined by a series of opposing annular stops positioned at different axial locations within the housing, and wherein hydraulically pressurizing the flow bore of the mandrel moves each of the plurality of pistons and the attached mandrel in the proximal direction, thereby pulling upward on the slip actuator, and the at least one slip to remove the section of casing from the cement jacket that surrounds the casing.
