Abstract: A pump device for extracting one or more resources includes a pump apparatus, a processor configured for receiving information from one or more sensors and sending instructions to one or more electronic controls, where the sensors and the electronic controls are each placed proximate to a respective component of the pump apparatus, and a network interface configured for sending and receiving communication from a device through a network.

Abstract: A pump jack system for reciprocating a pump rod string is made up of a base frame and piston drive cylinders mounted on the base frame with the upper end of the pump rod connected to the cylinder assemblies, the cylinder assemblies being operated in unison by a fluid control circuit communicating with inner and outer concentric fluid passages, and the pump rod string is counterbalanced by a fluid circuit which supplies pressure in an upward direction to each of the pistons on each upstroke and substantially reduces the pressure on each downstroke, the fluid circuit being selected from an inert gas alone or an inert gas pressurizing a hydraulic fluid. The fluid control circuit includes a directional control valve and timer, along with a fluid dampener, which is automatically responsive to dampen pressure surges and acceleration shocks at the beginning of each upstroke and downstroke.

Abstract: A device insertable into a cased well consisting of an elastic tube, a pipe having an inner bore, the pipe extending through the elastic tube, the elastic tube annularly surrounding an expansion space; tube clamps capable of fixedly attaching the upper and lower ends of the elastic tube to the outer surface of the pipe; and fluid transfer apertures capable of carrying fluids from the inner bore of the pipe to the expansion space, the fluid transfer apertures interconnecting the expansion space and the inner bore of the pipe so that, upon extension of the device into the cased well, and upon introduction of a pressurized water into the inner bore of the pipe, the water may flow from the inner bore of the pipe into the expansion space, causing the outer surface of the elastic tube to expand radially outward into is contact with the well's casing.
