Abstract
An artificial lift system provides an under pumping mitigation functionality through the use of a controller that adjusts a sucker rod pump's pumping speed. The controller determines whether: (a) the fillage level of the pump is equal to or above a pre-determined fillage level. The controller also determines whether the fluid level in the wellbore in which the pump is positioned is not decreasing. and increases the pumping rate of the pump if, over a given period, both (i) the fluid level is not decreasing and (ii) the pump fillage level is above the predetermined fillage level.
