Abstract
A system for enhancing a flow of a fluid induced by a rod pumping unit is provided. The system includes one or more sensors and a pumping control unit configured to control stroke movement of the rod pumping unit. The pumping control unit is configured to: (a) initiate at least one stroke of the rod pumping unit; (b) receive sensor data from the one or more sensors; (c) upon determination of a violation of a first set of constraints, make a first adjustment to the current stroke timing, and return to step (a); (d) upon determination of a violation of a second set of constraints, make a second adjustment to the current stroke timing, and return to step (a); and (e) upon determination of no violation of at least one set of constraints make a third adjustment to the current stroke timing, and return to step (a).
