Abstract: An ESP assembly is broken into subassemblies to fit through a lubricator for live well deployment. A lifting device has a shaft transmission feature and associated housing rotational lock for use at the top of the first subassembly and to be left in position for engagement of the next assembly. The subassemblies can be delivered on wireline or slickline. A wet connect can be at the lower end of the initial subassembly to connect to a cable run alongside the production tubing. The ESP subassemblies all are interconnected in the live well and function as they would if assembled at the surface. The ability to break down the assembly and run it in segments lets the components fit through a length limited lubricator for live well deployment.

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.
