    Abstract: An apparatus and method for pumping fluids, such as water and/or hydrocarbons, from a subterranean formation or reservoir, include a linear rod pump having a mechanical rack and pinion drive arrangement, adapted for attachment to a pumping mechanism, such as the polished rod at the top of a rod string in a hydrocarbon well. The rack gear, of the rack and pinion drive arrangement, is adapted for connection to, and movement with, the polished rod. The pinion gear does not translate with the rack gear, and is driven by a reversible motor for affecting up and down reciprocating motion of the rack gear and pumping mechanism. Some forms of the invention include a compressible gas counter-balance arrangement. Some forms of the invention include an electronic drive configured for dealing with electric power generated by the motor during a portion of the pumping cycle.

    Abstract: A dual component density sampler determines at least one of a density of water and a density of oil in a mixture of oil and water extracted from an oil well during production. A three-way valve is coupled to the oil well, with the three-way valve having a first output port and second output port. A dual-in-single-out manifold is coupled to the first output port. A segregation tank separates the water and oil, and has an entrance tank and exit tank. An entrance of the entrance tank is coupled to the second output port, and an exit of the entrance tank is coupled to an entrance end of the exit tank. An exit end of the exit tank is coupled to the dual-in-single-out manifold. A coriolis meter is coupled to the dual-in-single-out manifold, and is configured to selectively measure a density of the fluid mixture, the oil, and the water.

    Abstract: A method to dislodge debris from a pump system in which the pump system includes a down-hole pump coupled by a rod string to an above-ground pump actuator, which is coupled to a controller configured to operate the pump system, and where the actuator has an adjustable stroke length. The method also includes determining that the pump system should begin operating in a pump clean mode, implementing the pump clean mode configured in the controller, and cycling the pump actuator at a preset command speed using a preset starting stroke length, preset acceleration rate and a preset deceleration rate. The method also includes continuing to cycle the pump actuator while incrementally decreasing the stroke length by a preset stroke length increment resulting in increased pump cycling frequencies. Further, the method calls for determining that the pump clean mode is complete, and returning the pump system to a normal operation mode.

    Abstract: There is provided a system for producing oil from a well bore extending through a fossil fuel reservoir. The system includes a plurality of perforations defined in the casing proximate the fossil fuel reservoir. A gas flow tube is in communication with the annulus volume of the casing proximate the wellhead. A gas valve is coupled to the gas flow tube, with the gas valve configured to selectively open and close the gas flow tube. A controller, is coupled to the gas valve, with the controller configured to control the opening and closing of the gas valve. The opening and closing of the gas valve maximizes the volumetric rate of oil flow into the annulus volume through the perforations from the reservoir by displacing liquid in the annulus volume with a gas volume between the gas valve and the perforations.
