Abstract

The invention generally concerns an arrangement of a low volume submersible pump connected to a downhole gravity type oil-water separator. The low volume submersible pump is electrically powered using a flexible electrical cable that connects between the pump and electric power located at the ground surface. The low volume submersible pump is typically a positive displacement pump such as a piston pump or a hydraulically driven diaphragm pump but could be a centrifugal pump if the volumes produced are compatible with this method. The separator is located above or below the pump and is defined by an enclosed, pressure-tight volume created by a separate container or by two or three downhole packers. Located in the separator is a control valve that regulates the flow of oil and water from the separator to discharge tubes connected to the surface or to additional downhole apparatus.
