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.
Claims16
A non-transitory computer-readable medium embodying a program of machine executable instructions, comprising:
- instructions for receiving information from one or more sensors of a pump apparatus;
- instructions for transmitting commands to one or more electronic controls of the pump apparatus;
- instructions for transmitting and receiving communications from a device through a network for the pump apparatus;
- and
- instructions to perform a pump height adjustment procedure for the pump apparatus, wherein
- the pump apparatus reciprocates a pump rod string in an oil or gas well, wherein
- the instructions to perform the pump height adjustment procedure comprises
- instructions for receiving information from a proximity sensor of the pump apparatus configured to indicate a proximate obstruction reading;
- instructions for determining, based on the proximate obstruction reading, that an obstruction external to the pump apparatus is proximate to a present height of an arm of the pump apparatus;
- instructions for reducing a maximum height of the arm for avoiding the obstruction;
- instructions for receiving information from the proximity sensor indicating a next proximate obstruction reading;
- instructions for determining, based on the next proximate obstruction reading, that the obstruction is no longer proximate to the arm;
- and
- instructions for returning the maximum height of the arm to a pre-determined height, wherein
- the pump apparatus comprises
- a ground-engaging base frame, wherein an upper end of the pump rod string extends upward through the base frame;
- a first unit mounted on said base frame, wherein the first unit includes an inner concentric piston shaft and an outer diameter cylinder, and wherein a piston ram is in slidably sealed engagement through the inner concentric fluid passage;
- a second unit for introducing and removing of fluid to the first unit, wherein the introducing and removing of the fluid drives the piston ram in the inner concentric piston shaft;
- and
- the arm comprising a cross bar connected to the piston ram, a piston of the second unit, and the pump rod.

A method for operating a pump apparatus, comprising:
- mounting a first and second unit of the pump apparatus on a frame, wherein the first unit comprises a piston ram slidable in sealed engagement through an inner concentric piston shaft and an outer diameter cylinder in an outwardly spaced concentric relation to the inner concentric piston shaft mounted for movement with the piston ram, wherein the second unit is in fluid communication with the first unit, and wherein a pump rod extends downwardly into the subsurface formation and is connected to the piston ram;
- counterbalancing a weight of the pump rod with a fluid in the first and second unit;
- reciprocating the pump rod from a first position to a second position through simultaneous movement of the piston ram, wherein the pump rod and the piston ram are connected to a cross bar;
- receiving information from one or more sensors of the pump apparatus;
- transmitting commands to one or more electronic controls of the pump apparatus;
- transmitting and receiving communications from a device through a network for the pump apparatus;
- performing a pump height adjustment procedure for the pump apparatus;
- receiving information from a proximity sensor of the pump apparatus configured to indicate a proximate obstruction reading;
- determining, based on the proximate obstruction reading, that an obstruction is proximate to a present height of the cross bar;
- reducing a maximum height of the cross bar for avoiding the obstruction;
- receiving information from the proximity sensor indicating a next proximate obstruction reading;
- determining, based on the next proximate obstruction reading, that the obstruction external to the pump apparatus is no longer proximate to the cross bar;
- and
- returning the maximum height of the arm to a pre-determined height.
