Abstract: Apparatus for cleaning a surface with a liquid jet, the apparatus having: a main housing; a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end; a gear assembly configured to engage the primary fluid conduit and rotate the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a motor mounted to the main housing and configured to engage the gear assembly and thereby rotate the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a bifurcated head connected to the primary-fluid-conduit fluid-exit end, the bifurcated head having at least one fluid conduit; a hydraulic cylinder; a hydraulic-cylinder rod having a first end and a second end; a pivot pin having a longitudinal axis and the pivot pin being attached to the bifurcated head; a nozzle connected pivotally to the pivot pin; the hydraulic cylinder mounted to the main housing and configured to move the hydraulic-cylinder rod along a linear path by exerting a unidirection

Abstract: Motorized single-machine multi-pump apparatus and closed-loop methodology interconnected with a gas pipeline at a natural gas production well, using pressurized gas flow and differential pressure to drive a pumping system regulated by pneumatic controls using self-generated clean, low-pressure instrument air. The apparatus is connected to the gas flow line and the outlet is connected back into the gas flow line at lower pressure, creating a differential pressure corresponding to the source of motive power for actuating a piston which is directly connected to a plurality of plungers. This plurality of plungers is alternately pushed into and pulled out of corresponding plunger-cylinders for creating an integral drive and pump system prerequisite for gas well site pumping operations. Instead of venting to the atmosphere, well gas is returned to the flow line whereupon only clean air from the self-generated instrument air circuit is vented into the atmosphere.

Abstract: A ventless gas-driven pumping system controlled via a plurality of pneumatic valves and associated switches, for driving a diversity of process pumps at a natural gas well site. The ventless pumping system is readily interconnected with any gas pipeline location and uses flowing well gas and consequent differential pressure to drive a plurality of pumps and related pneumatic controls exclusively using a continuous self-generated air supply. Only self-generated air and no well gas is vented into the atmosphere during pumping operations.

Abstract: A system for optimizing progressive cavity pump operation during oil and gas recovery is provided. By strategically disposing a plurality of sensors along the production tubing and sucker rod strings, progressive cavity pump operation and performance may be monitored real-time. As an important indicia of pump performance, dynamic fluid level is provided to the operator/end user on a real-time basis. Prerequisite to achieving pump optimization, dynamic fluid level and other pertinent data are analyzed and enables corrections to be made in the pumping system during operation. A computer system having sufficient inherent and adaptable expertise is provided to interpret pump conditions based upon a plurality of variables and parameters to increase or decrease pump production and to maintain a dynamic fluid level determined to be optimal or otherwise advantageous by the end user.
