Artificial lift with additional gas assist

A system for pumping a production fluid from a wellbore, comprising:

• a high pressure multiphase pump coupled to an outlet line and operable to pressurize a first mixture of a liquid and a gas so that at least a portion of the gas dissolves in the liquid;
• a jet pump:
• disposed in the wellbore proximate to a formation,
• coupled to the outlet line so that the second pump may receive the pressurized first mixture,
• having an inlet for receiving the production fluid, and operable to throttle the first mixture, thereby drawing the production fluid into the inlet, forming a second mixture comprising the first mixture and the production fluid, and allowing at least a portion of the dissolved gas to escape from the solution as the second mixture rises to a surface of the wellbore, thereby lowering a pressure gradient of the second mixture to increase a production rate of the production fluid;
• a wellhead sealing the surface of the wellbore;
• a return line coupled to the wellbore so that the return line receives the second mixture;
• a separator coupled to the return line and operable to deliver a gas portion of the second mixture to a gas return line and a liquid portion of the second mixture to a liquid return line;
• a gas production line having a control valve and coupled to the gas return line;
• a gas recycle line coupled to an inlet line of the multiphase pump and the gas return line and having a control valve;
• a liquid production line having a control valve and coupled to the liquid return line;
• a liquid recycle line coupled to an inlet line of the multiphase pump and the liquid return line and having a control valve, and
• a computer operable to deliver a first portion of the gas portion to the gas production line, a second portion of the gas portion to the gas recycle line, a first portion of the liquid portion to the liquid production line, and a second portion of the liquid portion to the liquid recycle line by controlling the control valves.
