Abstract:
An artificial lift system is disclosed for removing reservoir fluids from a wellbore. A downhole pump and a gas lift system are disposed in the wellbore. The gas lift system includes a first tubing string, and the downhole pump may be positioned with a second tubing string. Injected pressured gas from the gas lift system may commingle with and raise reservoir fluids from the wellbore through the first tubing string. The commingled gas and reservoir fluids may be separated in the wellbore, and the reservoir liquids may be brought to the surface through the second tubing string by the pump.
