Abstract

A method of operating a submersible pumping system includes the steps of placing the pumping system in a normal mode of operation and then detecting the possible presence of a gas slug in proximity to the pumping system by measuring a decrease in the load on the motor. Once the possibility of a gas slug has been detected, the method continues by placing the pumping system in a reduced speed cycle. The pumping system is kept in the reduced speed cycle until the absence of a gas slug in proximity to the pumping system is detected by evaluating two independent conditions within the pumping system.
