Artificial Lift System With Under Pumping Mitigation

An apparatus and method for use in an artificial lift system to provide under pumping mitigation functionality in which a sucker rod pump's pumping speed is adjusted through the use of a controller that determines whether: (a) the fillage level of the pump is equal to or above a pre-determined...

Beschreibung
Zusammenfassung:	An apparatus and method for use in an artificial lift system to provide under pumping mitigation functionality in which a sucker rod pump's pumping speed is adjusted through the use of a controller that determines whether: (a) the fillage level of the pump is equal to or above a pre-determined fillage level and (b) 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.
