Abstract
An assembly and method for completing a wellbore. The assembly includes a polished bore receptacle, a torque lock ring, and a left-hand threaded coupling. The torque lock ring is positioned inside the polished bore receptacle. The torque lock ring couples the polished bore receptacle to an upper completion assembly. The left-hand threaded coupling is positioned inside the polished bore receptacle. The left-hand threaded coupling receives a left-hand threaded surface of the upper completion assembly.
Claims20
A wellbore completion assembly comprising:
- an upper completion assembly comprising a joint comprising:
- a left-hand threaded surface on a first end of the joint;
- and
- a right-hand threaded surface on a second end of the joint, the second end opposite the first end;
- a polished bore receptacle defining a void extending from an uphole opening of the polished bore receptacle to a downhole opening of the polished bore receptacle;
- a torque lock ring positioned inside the void of the polished bore receptacle, the torque lock ring configured to couple the polished bore receptacle to the joint of the upper completion assembly uphole from the first end of the joint and within the polished bore receptacle;
- and
- a left-hand threaded coupling positioned inside the polished bore receptacle downhole from the torque lock ring, the left-hand threaded coupling configured to receive and connect to the left-hand threaded surface on the first end of the joint of the upper completion assembly.
