Novel completion method for rigless intervention where power cable is permanently deployed

摘要

A submersible-pump assembly has an electric motor and pump adapted to be lowered into a string of production tubing. A permanently-deployed power cable is located in the annulus located between an outer surface of the production tubing and an inner surface of a string of casing. A set of wet-mateable power connectors provide electricity to the motor through hydraulically-actuated pins carried in hydraulic cylinders mounted to the outer surface of the production tubing. The power cable is connected to each pin for carrying electricity from the surface of the well to the pins. The pins are moved inward toward the motor to engage receptacles located in the outer surface of the motor. Alternatively, the power connectors may be a receptacle that receives a stab mounted to the tubing.
