Revised characteristics curve optimizes jet pumping

06/25/2001
A revised characteristics curve provides a method for optimizing jet pump designs by taking into account the influence of solution gas and the different densities of the power and produced fluids.For jet pumps in a conventional pipe string, the pump provides the only path for both oil and gas, and solution gas will influence pump operation whenever the pump intake pressure is less than the saturation pressure.If the jet pump can produce the same volume of the gas-liquid mixture as the pure liquid, then average density of the produced mixture can be calculated from the gas-liquid ratio at the pump intake, and this provides the basis for a revised characteristics curve with solution gas.Als...
