Abstract (en)
[origin: WO2017004110A1] Methods and apparatus to determine production of a downhole pump are described herein. An example method includes measuring a first amount of liquid produced from a well by a pump during a first stroke of the pump, computing a first pump card based on the first stroke, determining a first area of the first pump card and determining a leakage proportionality constant of the pump based on the first amount of liquid produced and the first area. The example method also includes computing a second pump card based on a second stroke of the pump, determining a second area of the second pump card and determining a second amount of liquid produced by the pump during the second stroke based on the leakage proportionality constant and the second area.
