ABSTRACT:
A method for monitoring a rod pumped well to detect various problems, i.e., fluid pound, rod parts, pump problems, high fluid levels, imbalance of the pumping unit, rate of production and others. The method utilizes measurements made at the surface to calculate a downhole pump card. The method utilizes the downhole pump card to detect the various pump problems and control the pumping unit.
