Patent Number Title Of Patent Date Issued
5782608 Method and apparatus for controlling a progressing cavity well pump July 21, 1998
A method and apparatus for controlling the speed of a progressing cavity liquid well pump by driving the pump with a variable speed drive device while measuring the amount of liquid production from the pump. The speed of the pump is varied in speed steps, either upwardly or downwardly, b
5167490 Method of calibrating a well pumpoff controller December 1, 1992
A method of calibrating a well pumpoff controller by calibrating the controller for determining the average load during a pumping stroke, measuring the actual load and averaging the measured maximum and minimum load during each operational stroke, comparing the average measured load
5064348 Determination of well pumping system downtime November 12, 1991
In a liquid well pumping system which is provided with a downtime between pumpoff cycles, the method of determining the maximum downtime includes running a plurality of tests to determine the relationship between runtime and downtime and determining when the relationship becomes non-line
4973226 Method and apparatus for controlling a well pumping unit November 27, 1990
A method of maintaining a substantially constant amount of filling of a liquid well pump actuated by a polished rod which is reciprocated by a prime mover. The load and position of the polished rod is periodically measured to determine the amount of filling of the pump. The change in the
4738313 Gas lift optimization April 19, 1988
Optimizing the production of well fluids from a well by controlling the injection gas flow rate. Determining the time delay for various gas flow rates to produce a constant liquid flow rate and determining the relationship between the injection gas flow rate and the amount of liquids
4509552 Gas gun for determining the liquid level of a well April 9, 1985
A gas gun for producing pressure pulses for measuring the liquid level in a well. A body is adapted to be connected to a well and includes first and second chambers which are interconnected by a passageway. Pressure pulses flowing between the chambers creates a pressure pulse for transmi
4268228 Hydraulic pumping unit May 19, 1981
A hydraulic pumping unit for vertically actuating a downhole pump including first and second hydraulic piston and cylinder assemblies. The first assembly is connected to the downhole pump and the second assembly is connected to a counterweight. A hydraulic line is connected between the
4090405 Polished rod load transducer May 23, 1978
A polished rod load transducer for connection to the polished rod for measuring the load in a sucker rod well pumping system in which the transducer body has at least three symmetrical sections pivotally connected together with a clamping means connected to the body for clamping the
3953777 Control circuit for shutting off the electrical power to a liquid well pump April 27, 1976
A control circuit for turning off the power to the pump drive motor when the pump has exhausted the supply of liquid in the well. Means for sensing the instantaneous current to the pump motor and a circuit measuring the average current drawn by the pump drive motor, and turning off the p
3931559 Malfunction detector circuit for the use with a pump-off control circuit January 6, 1976
A malfunction detector circuit for use in conjunction with a pump-off control circuit which is periodically actuated by a timer and which monitors the current drawn by the drive motor of a liquid well pump. The malfunction circuit monitors the operation of the timer, pump-off control
