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.

Claims (9)

WHAT IS CLAIMED IS:
1. A method of removing a section of casing from a cased well, comprising: providing a casing pulling tool comprising: 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 the mandrel, wherein the housing comprises a slip cage portion having at least one window through which the at least one slip can be radially outwardly deployed; and at least one piston coupled to the mandrel, wherein the piston is disposed within and axially movable with respect to the housing, wherein the piston is captured in a cylinder of the housing defined by opposing annular stops positioned at different axial locations within the housing, and wherein the piston is movable in a proximal direction along with the coupled mandrel in response to pressure being applied within the flow bore of the mandrel; connecting a rotary cutting tool to a distal end of the mandrel; displacing the mandrel in an axial direction relative to the housing to deploy the at least one slip to engage and grip and section of casing; rotating the mandrel to operate the cutting tool to cut the casing as the slide member, the at least one slip, and the reinforced slip actuator remain stationary and lodged in gripping engagement with the section of casing; cutting the casing to provide a detached section of casing gripped by the casing pulling tool; hydraulically pressurizing the flow bore of the mandrel to move the piston 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 a cement jacket that surrounds the casing; and withdrawing the casing pulling tool, the cutting tool, and the detached section of casing from the well.
2. The method of claim 1, wherein displacing the mandrel in an axial direction relative to the housing to deploy the at least one slip comprises: pulling upward on a collet of the casing pulling tool, the collet being located distal to the at least one slip and releasably engaged with a profile of an outer surface of the mandrel; transferring an upward force from the collet to a collet cage surrounding the collet; and pressing upward on the at least one slip via the collet cage to deploy the slip.
3. The method of claim 1, further comprising reducing friction between a rotatable component coupled to the housing and a stationary component coupled to the slip actuator during rotation of the mandrel and the cutting tool via a bearing assembly disposed between the rotatable component and the stationary component.
4. The method of claim 1, 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.
5. A system for removing a section of casing from a cased well, the system comprising: 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 the mandrel, wherein the housing comprises a slip cage portion having at least one window through which the at least one slip can be radially outwardly deployed; a rotary cutting tool coupled to a distal end of the mandrel; and at least one piston coupled to the mandrel, wherein the piston is disposed within and axially movable with respect to the housing, wherein the piston is captured in a cylinder of the housing defined by opposing annular stops positioned at different axial locations within the housing, and wherein the piston is movable in a proximal direction along with the coupled mandrel in response to pressure being applied within the flow bore of the mandrel; wherein displacing the mandrel in an axial direction relative to the housing deploys the at least one slip to engage and grip the section of casing; wherein the mandrel is rotatable to operate the cutting tool while the at least one slip and the slip actuator remain stationary and lodged in gripping engagement with the section of casing; and wherein pressurizing the flow bore of the mandrel causes the piston and the attached mandrel to move in the proximal direction pulling upward on the slip actuator, the at least one slip, and the section of casing.
6. The system of claim 5, wherein pressurizing the flow bore of the mandrel causes the piston and the attached mandrel to move in the proximal direction pulling upward on the mandrel, the slip actuator, and the at least one slip to remove the section of casing from a cement jacket that surrounds the casing.
7. The system of claim 6, 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 pressurizing the flow bore of the mandrel moves each of the plurality of pistons and the attached mandrel in the proximal direction.
8. The system of claim 5, further comprising a bearing assembly disposed about the mandrel and at a location between a rotatable component coupled to the housing and a stationary component coupled to the slip actuator.
9. The system of claim 5, further comprising a collet assembly disposed distal to the at least one slip, wherein the collet assembly comprises: a collet releasably engaged with a profile of an outer surface of the mandrel; and a collet cage surrounding the collet: wherein displacement of the mandrel in an axial direction relative to the housing pulls upward on the collet and transfers an upward force from the collet through the collet cage and to the at least one slip.
