An oil recovery device and method of use where a submersible pump is in combination with a hydraulic motor. The hydraulic motor is actuated by a pressure differential between hydraulic power lines extending between the motor and a regulation means at or near the surface. A monitoring system evaluates, communicates, and records operation parameters so that they may be adjusted to ensure a constant volume or production oil. The device may operate at variable speeds and in reverse.
