ARTIFICIAL LIFT TECHNOLOGY

The use of artificial means to increase the flow of liquids, such as Cruid oil or water from production well. Generally this is achieved by the use of mechanical device inside the well known as pump or velocity string.

Artificial lift is needed in wells when there is insufficient pressure the reservoir to lift the produced fluids to the surface.

ESP consists of a down hole pump ( a series of centrifugal pumps) an electrical motor which transforms the electrical power into kinetic energy to turn the pump, a separator or protector to prevent produced fluids from entering the electrical motor and an electric power cable that connects the motor to the surface control panel. ESP can handle a very wide range of flow rates from 200-90000 barrels.
