Abstract
Apparatus for deploying and energizing pumping apparatus including a submergible electric motor comprises a cable socket assembly and a cable connecting-and-sealing chamber assembly. The cable socket assembly has a housing that is connected at a lower end to an upper end of a housing of the cable connecting-and-sealing chamber assembly, the lower end of which is connected to a housing of the motor. The upper end of the housing of the cable socket assembly has an attachment portion provided with a breakaway connection to a weight-bearing cable. An electrical cable extends through the housing of the cable socket assembly to the housing of the cable connecting-and-sealing chamber assembly, which is divided by the body of a penetrator into upper and lower chambers. Sets of conductors in the chambers are connected, respectively, to the electrical cable and to the motor, and are interconnected with each other via feed-through elements (mandrels) associated with the body. The chambers are filled with fluid that excludes well fluid. If the pumping apparatus becomes stuck downhole, the cables may be disconnected from the pumping apparatus and pulled from the well. Then the pumping apparatus…
