Electric Submersible Pump System (EPS)
product overview
The electrical submersible pump, typically called an ESP, is an efficient and reliable artificial-lift method for lifting moderate to high volumes of fluids from wellbores. Variable-speed controllers can extend range significantly, both on the high and low side. The ESP’s main components include:
Multistaged centrifugal pump
Three-phase induction motor
Seal-chamber section
Power cable
Surface controls
ADVANTAGE
Adaptable to highly deviated wells; up to horizontal, but must be set in straight section.
Adaptable to required subsurface wellheads 6 ft apart for maximum surface-location density.
Permit use of minimum space for subsurface controls and associated production facilities.
Quiet, safe, and sanitary for acceptable operations in an offshore and environmentally conscious area.
Generally considered a high-volume pump.
Provides for increased volumes and water cuts brought on by pressure maintenance and secondary recovery operations.
Permits placing wells on production even while drilling and working over wells in immediate vicinity.
Applicable in a range of harsh environments.
