Iranian Specialists Attain Technology to Produce ESP Downhole Pump Drives
“The company's products are in the petrochemical and oil and gas fields, and we have made a product called ESP (electric submersible pumps) downhole pump drives,” said Sepahkar, the managing-director of the company.
Noting that these pumps are used at a depth of 3,000 meters to rehabilitate half-life wells, he said, "Hi-tech and special technologies are required to operate these types of wells, and these drives are used to operate them due to their high voltage and harsh environmental conditions, and our company's technologists have achieved the technical know-how to produce them.”
“Few manufacturers in the world have produced these systems, and they play an important role in rehabilitating and making wells more productive."
More than 90% of all producing oil wells require some form of artificial lift to increase the flow of fluids from wells when a reservoir no longer has sufficient energy to naturally produce at economic rates or to boost early production to improve financial performance. One of the most versatile and adaptable artificial lift methods is electric submersible pumping.
Deployed in an estimated 150,000 to 200,000 wells worldwide, electric submersible pumps (ESPs) consist of multiple centrifugal pump stages mounted in series within a housing mated to a submersible electric motor. These pumps are connected to surface controls and electric power by armor-protected cables.
