  • Submersible pumping system and method for boosting subsea production flow
    Patent number: 7914266
    Abstract: A booster pumping system is disclosed for producing hydrocarbons from a subsea production well. The booster pumping system includes: (1) a submersible pump hydraulically connected to the production well to provide energy to the hydrocarbon flow and boost production to another destination such as a subsea production facility or the surface via a riser; (2) an inlet conduit to receive the flow from the production well and isolate the flow from the dummy wellbore and direct the flow to the intake of the pump; and (3) a motor exposed to the dummy wellbore to drive the pump. The dummy wellbore may be flooded or circulated with seawater to cool the motor.
