Hydraulically Assisted Deployed ESP System

摘要

A system and method for providing artificial lift to production fluids within a subterranean well includes loading an electrical submersible pump assembly into an interior cavity of a pump launcher. The electrical submersible pump assembly has a motor and a pump and is releasably secured to a piston device. The piston device has an outer diameter profile. The pump launcher is releasably secured to a wellhead so that the interior cavity is in fluid communication with an inner bore of a production tubing that extends a length into the subterranean well. A propulsion system is activated to move the electrical submersible pump assembly from the pump launcher and into the subterranean well. The piston device can be communicated with to control the descent of the electrical submersible pump assembly through the subterranean well.

1. A method for providing artificial lift to production fluids within a subterranean well, the method comprising:
loading an electrical submersible pump assembly into an interior cavity of a pump launcher, the electrical submersible pump assembly having a motor, and a pump and being releasably secured to a piston device, the piston device having an outer diameter profile; releasably securing the pump launcher to a wellhead so that the interior cavity is in fluid communication with an inner bore of a production tubing that extends a length into the subterranean well; activating a propulsion system to move the electrical submersible pump assembly from the pump launcher and into the subterranean well; and communicating with the piston device to control a descent of the electrical submersible pump assembly through the subterranean well.
