What components are included in ESP?

The electrical submersible pump system, typically called an ESP, is an efficient and reliable artificial-lift method for lifting moderate to high volumes of fluids from wellbores. These volumes range from a low of 150 B/D to as much as 150,000 B/D (24 to 24,600 m3/d).
The electric submersible pump system consists of the surface equipment, the electric transmission part and the down hole equipment. The surface equipment includes transformer, control panel (VSD). junction box and the ground cable etc. Down hole equipment includes the motor, protector, gas separator, submersible centrifugal pump and the submersible power cable etc. The components are normally tubing hung from the wellhead with the pump on top and the motor attached below.
