EFFECTS OF GAS VOLUME FRACTIONS ON ELECTRICAL SUBMERSIBLE PUMP PERFORMANCE UNDER TWO-PHASE FLOW
An Electrical Submersible Pump (ESP) is the most commonly used artificial lifting method in the oil and gas industry through conversion of kinetic energy to pump pressure head; however, issues like gas entrainment and shifting production rates tend to cause ESP pressure degradation.Flow behaviours inside the ESP, such as gas pockets or pressure sur
