Abstract: A production pump for lifting subterranean fluids to the surface of the earth. The production pump is formed from a housing having a pumping unit disposed within the housing. The housing further has a first end defining a first chamber that provides a fluid intake for the pump unit. The housing further has a second end defining a second chamber that provides a fluid outlet for the pump unit. Additionally, the pump includes a conduit that extends from the second end of the housing into the first chamber to provide fluid to the first chamber.

Abstract: A fluid separation system is disclosed for installation within a wellbore that penetrates a production formation and a discharge formation. The system comprises a first pump and a second pump each operatively connected to a means for operation, such as a downhole electric motor, and a fluid separator for separating wellbore fluids from the production formation into a first stream and a lighter second stream. Wellbore fluids are introduced into the first pump, and are then conveyed to an inlet of the fluid separator. The second stream exiting the fluid separator is conveyed to an inlet of the second pump, and from the second pump to the earth's surface. Devices are included, such as wellbore packers, to isolate the discharge formation from the production formation, so that the second stream exiting the fluid separator directly enters the discharge formation.

Abstract: A plug-in electrical connector for use with an electrical submergible pumping system comprises a pothead having a first electrical connector member surrounded by a sleeve of insulative material extending from the pothead, and a terminal block with a recess therein adapted to receive thereinto the sleeve on the pothead and with a second electrical connector member set within the recess. The sleeve and the recess configured and sized to form a circuitous arc path, and the second electrical connector member is adapted to form an electrical connection with the first electrical connector member. A fluidic seal is included at the interface of the pothead and the terminal block. The circuitous arc path prevents shorting out by greatly increasing the distance shorting material, such as water, must travel from one phase to another phase or to ground.
