An ESP system is considered an effective and economical means of lifting large volumes of fluids from great depths under a variety of well conditions.
A well is installed with artificial lift system when its production cannot flow naturally to surface or when is needed to boost the oil production to make the well commercially economic.
ESP systems used in oil wells are multistage centrifugal pumps driven by an electric motor. The pump and motor are suspended by the production tubing, with the motor positioned below the pump in a producing well and the pump discharging directly into the production tubing. Power is supplied to the motor through a three conductor cable, which is run down to the motor from surface along with the tubing / casing annulus.
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. These volumes range from a low of 150 B/D to as much as 150,000 B/D. Variable-speed controllers can extend this range significantly.
The submersible pump system consists of both downhole and surface components. The main surface components are transformers, motor controllers, junction box and wellhead. The main downhole components are the motor, seal, pump and cable.
In order to improve oil production in Latin America, Southern Procurement Services (SPS) executes the third Electro submersible pump equipment acquisitions, power cables, Variable speed drivers and electrical transformers which are from Russia, Ukraine, Argentina and China, to Ali Primera Harbor, located in Zulia Estate.
The purpose of this system (ESP System) is to achieve the artificial lifting of crude oil goal. It was said that the last pump was removed and, after its evaluation, it was determined that the equipment did not work because it contained sand inside, so it was replaced by this new system to reactivate the well.
