A submersible well pump and downhole completion system. The system includes a fluid flow path from the well surface to inject lubricating fluid to increase downhole pump life and/or corrosion inhibitors to protect downhole components from potentially harmful well fluids. The system substantially increases the service life of downhole components used to enhance the production of well fluids. The system also offers ease of assembly at the well surface and installation at the desired downhole location.

A well completion system for a downhole submersible pump and motor comprising: a. a production tubing string with a landing nipple forming an integral part thereof and defining in part a downhole location for releasably anchoring a submersible pump and related components within the production tubing

A well completion system for a downhole submersible pump and motor comprising: a. a production tubing string with a landing nipple forming an integral part thereof and defining in part a downhole location for releasably anchoring a submersible pump and related components within the production tubing string; b. a power cable having electrical conductors and fluid conductors to supply both electricity and treating fluid from the well surface to the submersible pump and related components; and c. a fluid flow path extending through the submersible pump motor and its related components to receive treating fluid from the power cable. The method of installing and operating a downhole submersible pump and motor comprising: a. attaching the submersible pump with its motor and related components to a power cable having electrical conductors and a fluid conductor to supply both electricity and treating fluid from the well surface to the submersible pump motor and related components; b. lowering the submersible pump, motor and related components by the power cable through a production tubing string to a landing nipple which defines in part a downhole location for releasably anchoring the submersible pump and related components within the production tubing string; and c. injecting treating fluid from the well surface through the power cable to a fluid flow path extending through the submersible pump motor and its related components.
