Producers use artificial lift systems in more than 90% of oil wells. Artificial lift is used to increase production fluids and are needed when reservoirs no longer have sufficient energy to naturally produce at economic rates, or to boost early production in new wells.
One effective and versatile method of artificial lift is the electric submersible pump.
Producers may choose to use an ESP system because they are quiet, safe and only require a small surface footprint.
They have a wide range of pump rate operation and can accommodate changes in fluid properties and flow rates over the life of the well. They’re also applicable in many corrosive environments.
An ESP system consists of multiple stages of centrifugal pumps which are connected to a submersible electric motor. The motor is powered by heavy duty cables connected to surface controls.
The motor rotates the shaft which is connected to the pump. The spinning impellers draw in fluid through the pump intake, pressurizing it and lifting it to the surface.
An inverted discharge design is configured the same, with the exception that the pump stages are inverted to pump fluids into the well formation from the surface. This configuration is typically used for injection of water into disposal wells.
