Abstract: A closed loop pneumatic pumping system is provided. The system uses a gas compressor and a high pressure gas tank to exert pneumatic pressure against a reciprocating piston over a wellbore. The piston is connected to a rod string and downhole pump for pumping formation fluids from a wellbore. The system includes an electronic controller that controls movement, including pump speed of the piston as it cycles between upstrokes and downstrokes within a cylinder over the wellbore. In one aspect, speed is controlled by adjusting a speed of the compressor. In another aspect, speed is controlled by adjusting the position of an upstroke control valve and a downstroke control valve. In one aspect, the pump stroke controller is configured to adjust a speed of the upstroke and a speed of the downstroke in response to signals indicative of pump fillage. A method for optimizing pneumatic pumping speed at a wellbore is also provided herein.

Abstract: A high pressure pump including a linear actuator comprising a servo motor to axially rotate a hollow rotor shaft in alternating directions, the servo motor having a stator positioned co-axially around the hollow rotor shaft with an interior of the rotor shaft being co-axially coupled to a drive member to convert axial rotation into reciprocal displacement, the drive member being constrained against linear movement and supporting a shaft. At least one piston is coupled to the shaft and the piston is arranged within a cylinder to define a pumping chamber, whereby alternating rotation of the rotor shaft causes reciprocal linear displacement of the piston to pressurize fluid in the pumping chamber. A drive mechanism includes a controller coupled to a servomotor and an encoder to measure movement of the hollow rotor or output shaft and send a feedback signal proportional to the movement to the controller.
