Abstract: Disclosed is a submersible pumping system that includes a motor, a production pump and a seal section disposed between the motor and the production pump. The pumping system further comprises an auxiliary pump disposed below the motor and an auxiliary adapter connected between the motor and the auxiliary pump.

Abstract: A submersible pumping system includes a pump assembly that is connected to a motor assembly. The pump assembly includes a pump intake having an intake hole, a pump housing connected to the pump intake and a pump discharge head connected to the pump housing. An intake seal device is connected to the pump intake and seals the pump intake prior to the initial use of the pump assembly. To further isolate the pump assembly while dormant, an outlet seal device can be fitted to the pump discharge head to isolate the pump assembly from the reservoir fluid in the production tubing.

Abstract: The present invention provides an electric submersible pumping assembly that includes an encapsulated pumping device containing a pump, an electric submersible motor, a sealing device at the top, and an opening device at the bottom. The lubricant-filled, initially sealed, encapsulated pumping device allows the pump and motor to be run in the wellbore without contamination and be left intact until operated.

Abstract: A downhole rotary water separation system for the separation and transfer of different density fluids in downhole applications using a pump, a motor, a rotary separator and a shaft-incorporated packer, as necessary, with a minimum of conduits and tubes. Torque can be transferred between all moving components as well as the packer such that the motor and pump can be disposed above or below the separator.

Abstract: The present invention provides a downhole water separation system with an encapsulated electric submersible pumping device for the separation and transfer of different density fluids in downhole applications. The encapsulated device works in conjunction with a separator and packer, using a pump assembly and a motor assembly that are contained in an enclosed device, to separate fluids with a minimum use of conduits. The pump and motor are part of an encapsulated single device, and the separation system arrangement permits the motor and pump to be either above or below the separator.

Abstract: The present invention provides a clean water separation system with an electric submersible pumping device and a surface separator and pumping device for the separation and transfer of different density fluids and solids. The electric submersible pumping device can be an encapsulated device that works in conjunction with a separator and pumping system that are located on the surface, to separate fluids and solids.
