A hydraulic torque locking mechanism is incorporated into a casing manipulation assembly. The hydraulic torque locking mechanism includes a clutch mechanism that is actuated using surface pump pressure from tool circulation. ## Claims ### Claim 1 A casing manipulation assembly for manipulation of a casing member and comprising: a central mandrel; a housing circumferentially surrounding the mandrel and being axially moveable with respect to the mandrel as the mandrel is rotated; a slip assembly having a slip member that is set within the casing member by axial movement of the mandrel with respect to the housing; and a torque locking mechanism to selectively prevent rotation of the mandrel with respect to the housing. ### Claim 2 (depends on 1) The casing manipulation assembly of claim 1, wherein the torque locking mechanism comprises a clutch assembly that is moveable between a first, unengaged position wherein the mandrel can rotate with respect to the housing, and a second, engaged position wherein the mandrel is locked against rotation with respect to the housing. ### Claim 3 (depends on 2) The casing manipulation assembly of claim 2, wherein the clutch assembly further comprises: a piston circumferentially surrounding the mandrel and moveably disposed within the housing; first and second clutch pads disposed within the housing that are selectively brought into engaged contact with each other by movement of the piston within the housing. ### Claim 4 (depends on 3) The casing manipulation assembly of claim 3, wherein the piston is moveable within the housing in response to hydraulic fluid pressure. ### Claim 5 (depends on 1) The casing manipulation assembly of claim 1, herein the mandrel further comprises a friction mechanism for engaging the casing member. ### Claim 6 (depends on 3) The casing manipulation assembly of claim 3, wherein the first and second clutch pads have complimentary, interlocking teeth. ### Claim 7 (depends on 2) The casing manipulation assembly of claim 2, wherein the clutch assembly is biased toward the unengaged position by a spring. ### Claim 8 A torque locking mechanism for use in a casing manipulation assembly having a mandrel and a housing circumferentially surrounding the mandrel, the torque locking mechanism comprising: a first clutch pad operably interconnected with the housing; a second clutch pad operably interconnected with the mandrel; the first and second clutch pads being moveable between an unengaged position wherein the clutch pads are not in engaged contact with each other to permit rotation of the mandrel with respect to the housing and an engaged position wherein the clutch pads are brought into engaged contact with each other to prevent rotation of the mandrel with respect to the housing. ### Claim 9 (depends on 8) The torque locking mechanism of claim 8, wherein the first and second clutch pads have complementary, interlocking teeth. ### Claim 10 (depends on 8) The torque locking mechanism of claim 8, further comprising a piston circumferentially surrounding the mandrel within the housing and wherein the first and second clutch pads are moved to the engaged position as the piston is moved axially within the housing. ### Claim 11 (depends on 10) The torque locking mechanism of claim 10, wherein the piston is moved within the housing by hydraulic fluid pressure. ### Claim 12 (depends on 8) The torque locking mechanism of claim 8, wherein the first and second clutch pads are biased toward the unengaged position by a spring. ### Claim 13 A method of engaging a casing member for manipulation, the method comprising the steps of: disposing a casing manipulation tool at least partially within a casing member, the casing manipulation tool having a mandrel and a housing circumferentially surrounding the mandrel; rotating the mandrel with respect to the housing to set a locking slip within he casing member; engaging a torque locking mechanism to prevent rotation between the housing and the mandrel. ### Claim 14 (depends on 13) The method of claim 13, wherein the step of engaging a torque locking mechanism further comprises interlocking first and second clutch pads. ### Claim 15 (depends on 14) The method of claim 14, wherein the step of interlocking first and second clutch pads further comprises moving a piston within the housing. ### Claim 16 (depends on 15) The method of claim 15, wherein the piston is moved by hydraulic fluid pressure. ### Claim 17 (depends on 13) The method of claim 13 further comprising the step of rotating the casing member, with the casing manipulation tool, after the torque locking mechanism is engaged.
