METHOD AND APPARATUS TO DETERMINE PRODUCTION OF DOWNHOLE PUMPS |
摘要 |
Methods and apparatus to determine production of downhole pumps are disclosed. An example method includes measuring an amount of liquid produced from a well by a pumping unit during a predetermined time period and determining first areas of first pump cards during the predetermined time period. The example method also includes summing the first areas and, based on the amount of liquid produced and the summed first areas, determining a leakage proportionality constant of a downhole pump of the pumping unit. |
