Abstract
A submersible pumping system for use in producing wellbore fluids from a wellbore within a subterranean formation includes a motor and a pump driven by the motor to produce the wellbore fluids. The pumping system further includes a self-supporting power cable connected to the pump. The self-supporting power cable includes a plurality of conductors and a plurality of strength members. A method of deploying and retrieving a submersible pumping system in a wellbore includes the steps of connecting a wireline to the submersible pumping system, connecting a self-supporting power cable to the submersible pumping system, lowering the submersible pumping system into the wellbore while the weight of the submersible pumping system is borne by the wireline. The method continues with the step of locating the submersible pumping system on a landing assembly, disconnecting the wireline from the submersible pumping system, and retrieving the wireline from the wellbore without removing the submersible pumping system from the wellbore.
