Abstract
A pumpjack is operated continuously over a sequence of two adjacent pump stroke cycles, by energizing an electric motor to operate the pumpjack over a first pump stroke cycle according to a motor speed profile over a plurality of discrete control periods within the cycle, while receiving sensory feedback from one or more sensors. In response to the feedback, and while continuing to operate the pumpjack, one or more speed adjustments are made to specific control periods, so as to alter the motor speed profile while continuing to operate the electric motor to drive the pump jack. The intra-cycle control optimizes flow while reacting to detrimental and changing conditions.
