Abstract
A tubular locking system comprises a first wellbore tubular, an internal locking feature disposed on an inner surface of the first wellbore tubular, a second wellbore tubular, where at least a portion of the second wellbore tubular is disposed within the first wellbore tubular, a compression sleeve coupled to the second wellbore tubular, a collet coupled to the second wellbore tubular below the compression sleeve, and a shifting sleeve disposed within the collet.
Claims29
A tubular locking system comprising:
- a first wellbore tubular;
- an internal locking feature disposed on an inner surface of the first wellbore tubular;
- a second wellbore tubular, wherein at least a portion of the second wellbore tubular is disposed within the first wellbore tubular;
- a compression sleeve coupled to the second wellbore tubular;
- a piston that comprises a hydraulic chamber formed by a surface of the compression sleeve and a portion of the second wellbore tubular;
- a port configured to provide fluid communication between a flow passage through the second wellbore tubular and the hydraulic chamber;
- a collet coupled to the second wellbore tubular below the compression sleeve;
- and
- a shifting sleeve disposed within the collet.

A method comprising:
- disposing a first wellbore tubular in a wellbore, wherein the first wellbore tubular comprises a locking feature disposed on an inner surface of the first wellbore tubular;
- providing a second wellbore tubular within the first wellbore tubular, wherein the second wellbore tubular comprises an axial locking mechanism coupled thereto, and wherein the axial locking mechanism comprises:
- a compression sleeve coupled to the second wellbore tubular;
- a collet coupled to the second wellbore tubular below the compression sleeve, wherein the collet comprises a collet mandrel comprising a plurality of longitudinal slots;
- and a collet protrusion disposed on the outside surface of the collet mandrel;
- and
- a shifting sleeve disposed within the collet;
- wherein the compression sleeve is slidingly coupled to the second wellbore tubular, and wherein the axial locking mechanism further comprises:
- a piston that comprises a hydraulic chamber formed by an surface of the compression sleeve and a portion of the second tubular, and
- a port configured to provide fluid communication between a flow passage through the second wellbore tubular and the hydraulic chamber;
- positioning the locking feature between the collet protrusion and the compression sleeve;
- and
- shifting the shifting sleeve into an activated position.
