Abstract
A system located in a subsea environment is disclosed comprising a submersible pump positioned in a well, a hydraulic motor that is operatively coupled to the submersible pump and a pressurized fluid supply pump that is positioned on or near a floor of the subsea environment and in fluid communication with the hydraulic motor.
Claims26
A system located in a subsea environment, comprising:
- a submersible pump positioned in a well,
- a hydraulic motor that is operatively coupled to said submersible pump;
- and
- a pressurized fluid supply pump that is positioned within said subsea environment, said pressurized fluid supply pump being in fluid communication with said hydraulic motor.
1 more element
A system located in a subsea environment, comprising:
- a production tree positioned above a well, said production tree having a production outlet;
- a submersible pump positioned in said well,
- a hydraulic motor that is operatively coupled to said submersible pump;
- a booster pump that is adapted to receive a hydrocarbon fluid from said production outlet;
- and
- a pressurized fluid supply pump that is positioned on or near a floor of said subsea environment, said pressurized fluid supply pump being in fluid communication with said hydraulic motor.
