During the well operation, mechanical impurities are carried out from the formation into the well with the fluid. These solids are abrasives of reservoir rock, salts, unfixed proppant, solid inclusions from killing fluids, and corrosion products of downhole equipment.
Often, solids emissions have a volleying nature, and the content of such solids may reach ultra-high values. The solids, getting into the pump, subject it to abrasive wear, clog the operating devices, block the movement of the shaft and lead to its breakdown.
To limit the impact of solids, expensive wear-resistant equipment, upstream devices, and regular flushing of a submersible pump are usually used. This means idling equipment during this process, incurring loss in production and profits.
Our solution is based on the Lex Ultra-High-Speed ESPs (UHS ESPTM). By leveraging its modular design and using hard alloys and ceramic friction pairs to provide steady operation against the solids content of up to 2,000 ppm (2,000 mg/l), our technology can withstand four times the limits set by standard equipment.
Implementation of our solution reduces the risk of equipment failures, unforced downtime for workover, and potential production loss by 40%.
