Abstract:
A method of automatically washing a well casing of a progressing cavity (PC) pump system. The method includes disabling, via a controller, a normal speed control of a progressing cavity (PC) pump of the PC pump system, and closing, via the controller, a gas flow valve to stop upward fluid flow in an annulus of the well casing. The method further includes opening a wash valve to allow fluid from the wash fluid source into the well casing. Upon wash fluid accumulation within the annulus, the method further includes increasing the speed of the pump to begin flushing the well casing, and closing the wash valve.
