Abstract
A system for pumping high gas-to-liquid ratio well fluids. The system includes a submersible pumping system having a submersible motor and a submersible pump driven by the motor. The system further includes deployment tubing, such as production tubing or coiled tubing, through which wellbore fluid is produced. A bypass is connected into the system to conduct a portion of the wellbore fluid intaken by the submersible pumping system to a position upstream of the pump intake. Because this recirculated fluid has a lower gas-to-liquid ratio and a lower viscosity, its reintroduction into the new wellbore fluid promotes efficiency of pumping and decreased wear on pumping system components.
