Abstract
Instantaneous speeds of revolution for a beam pumping unit prime mover rotor, determined for all or a predetermined part of the pumping unit reciprocation cycle, are applied to compute one or more parameters of pumping unit performance, which are compared to predetermined values for such parameters to detect the existance of cause (such as pump-off, mechanical malfunction, electrical operating inefficiency or pumping unit imbalance) for correction of pumping unit operation, which is done if indicated by the comparison.
