  • POLISHED ROD-MOUNTED PUMP CONTROL APPARATUS
    Publication number: 20150345280
    Abstract: A method and apparatus for controlling a pump configured to pump liquid out of a well is described. A compact sensor package including a force sensor, position sensor, PLC, and transmitter may be disposed at a single location of the pump and communicate with a pump controller.

  • Pumpjack production control
    Patent number: 8910710
    Abstract: A method, software, and apparatus for controlling a pump configured to pump liquid out of a well. Such control may involve determining whether a production rate of gas from the well is increasing, decreasing, or steady, and whether to switch the pump between an OFF state and an ON state. Whether the pump is switched may depend upon whether the production rate of the gas is determined to be increasing, decreasing, or steady.

  • PUMPJACK TORQUE FILL ESTIMATION
    Publication number: 20140088875
    Abstract: The fill of a downhole pump of a pumpjack or other system may be estimated based on a dynamically changing a reference torque or force curve and actual torque or force measurements during at least a portion of a pump stroke. Using various techniques, the reference curve may dynamically change over time to take into account slowly changing operating conditions. Moreover, the reference curve and/or the measurements may be adjusted to ensure that the estimated and/or reported pump fill does not exceed 100 percent of pump capacity.
