ABSTRACT:
A cable suspended pumping system has a conventional subsurface safety valve, close to the surface, controlled by a conventional safety valve operating line. The safety valve is located in a tube that provides a flow passage through a packer. The cable is divided into an upper section above the packer and a lower section below the packer. The tube is suspended from the upper section of the cable, and the lower section of the cable is suspended from the tube. A submergible pumping unit is suspended from the lower section of the cable. The pumping unit includes an electrically driven pump having a discharge head that cooperates with a seating shoe for supporting the pump and for dividing the well into an intake zone and a discharge zone. Opposite ends of the tube are perforated so that production fluid may pass through the packer via the tube. Electric current carrying portions of the cable sections above and below the packer are joined by a cable packer penetrator extending through the packer.
