Abstract
A system for use in a well includes a completion system having a shoulder contact region, an electric submersible pumping system deployed downhole via a cable for landing on the completion system, a tubular member coupled to the electric submersible pumping system and extending downhole from the electric submersible pumping system, and a shoulder mechanism slidably mounted on the tubular member for engagement with the shoulder contact region during landing, the shoulder mechanism being selectively settable along the tubular member to counter tensile loading in the cable. The shoulder mechanism is set against the tubular member via anchors actuated against the tubular member, and the anchors are actuated by a piston movably mounted within a housing of the shoulder mechanism.
Claims15
A system for use in a well, comprising:
- a completion system disposed in a wellbore and having a shoulder contact region;
- an electric submersible pumping system deployed downhole via a cable for landing on the completion system;
- a tubular member coupled to the electric submersible pumping system and extending downhole from the electric submersible pumping system;
- and
- a shoulder mechanism slidably mounted on the tubular member for engagement with the shoulder contact region during landing, the shoulder mechanism being selectively settable along the tubular member to counter tensile loading in the cable,
- wherein the shoulder mechanism is set against the tubular member via anchors actuated against the tubular member, and
- wherein the anchors are actuated by a piston movably mounted within a housing of the shoulder mechanism.
A system, comprising:
- a submersible pumping system sized for deployment in a borehole;
- a tubular member extending from the submersible pumping system;
- and
- a shoulder mechanism which may be shifted along the tubular member while the submersible pumping system is in the borehole, the shoulder mechanism having a setting feature by which the shoulder mechanism is selectively anchored to the tubular member,
- wherein the shoulder mechanism comprises a plurality of anchors selectively settable against the tubular member, and
- wherein anchors of the plurality of anchors are actuated via a hydraulic piston.
A method, comprising:
- connecting an electric submersible pumping system to a power cable;
- coupling a shoulder mechanism to the electric submersible pumping system via a stinger,
- deploying the electric submersible pumping system downhole into a wellbore via the power cable until the shoulder mechanism engages a shoulder contact region of a downhole completion;
- allowing the shoulder mechanism to slide along the stinger;
- and
- selectively locking the shoulder mechanism to the stinger to counter loading on the power cable,
- wherein selectively locking comprises shifting an anchor against the stinger via a pressure actuated piston.
