ABSTRACT:
A method and apparatus for commingling and producing fluids from an upper and lower reservoir wherein one of the reservoirs has a greater flow capacity than does the other. A jet pump is positioned adjacent the upper reservoir and uses the fluid from the higher-flow capacity reservoir as the power fluid for the pump. As the power fluid flows through a nozzle in the pump, it creates a lowered-pressure zone which sucks in the produced fluids from the other reservoir thereby forming a commingled stream of fluids. Where the upper reservoir has the greater flow capacity, a first embodiment of the pump uses the fluids from the upper reservoir as the power fluid. Where the lower reservoir has the greater flow capacity, the situation is reversed and a further embodiment of the pump uses the fluids from the lower reservoir as the power fluid.
