Abstract: A coil tubing electrical power cable system for use with a submersible pump in oil well and/or water well pumping applications. The cable includes a plurality of insulated electrical conductors enclosed in a low tensile strength corrosion-resistant metal tubing. The twist factor or lay length of the conductors is approximately eight to fourteen times the diameter of the insulated conductors in order to overcome the tensile loads and elevated temperatures which cause z-kinking. In addition, the electrical cable may include one or more hydraulic tubes.

Abstract: A coil tubing electrical power cable system is used to electrically drive a pump in an oil and/or water well. The cable is an insulated electrical conductor enclosed in a low tensile strength corrosion-resistant metal tubing. The tubing has the tensile strength to support the tubing in the electrical conductors. Separate retrievable support means are attached to the motor for supporting the motor and pump in the well. The motor and pump are lowered and set by the support means and the support means is then disconnected and retrieved and is not required to be corrosion-resistant.
