Abstract: A system for producing wellbore fluids. The system includes a pumping system deployable into tubing disposed in a wellbore, the pumping system includes a pump, a pump motor, a reservoir for containing purging fluid, and conductors in electrical communication with the pump motor. Electrical supply contacts in the tubing are connected to a downhole electrical power supply via a power cable extending along the tubing length from the surface. The conductors are engageable with the electrical supply contacts when the pumping system is landed within the tubing. Purging fluid in the reservoir can be flowed between the conductors and the supply contacts to remove conductive fluid prior to engaging the conductors and supply contacts. The conductors are selectively extended from a retracted position in the pumping system.

Abstract: A gas restrictor for an intake of a horizontally oriented submersible well pump has a tubular housing and a number of apertures. A sleeve is mounted within the housing for rotation relative to the housing. The sleeve has an axially extending row of slots. At least one weight in the sleeve causes the sleeve to rotate to a position with the row of slots at the bottom of the sleeve while the well pump is oriented horizontally. The slots and apertures are arranged so that regardless of the particular orientation of the housing relative to the sleeve, at least one of the apertures will be in registry with one of the slots.
