Borets completes successful US applications of WR2 system

Hydrocarbon Engineering,

Borets has successfully completed eight North American applications of its Wide Range Wear Resistant (WR2) pump system. The WR2 system has been designed for hash well conditions and has the ability to handle a wide range of production, abrasives and gas with the goal of extending run life.

The initial North American installation was completed on 15 May 2015, in a North West Oklahoma well designed to test the pump’s ability to handle a wide range of flow, gas slugs and flow back of frac sand over an extended period of time. The innovatively designed system utilises a proprietary manufacturing process to provide precise dimensional tolerances, enhanced surface finishes and no undersurface cavities. The WR2 incorporates a superior hydraulic design to result in improved efficiency and reliability, less stress on the system and longer operating life.

The WR2 pump reaches a high strength limit of 2100 MPa (304.5 Ksi). It is designed for flow rates of 250-1000 bpd (40-160m3/day) and 560-1900 bpd (90-300m3/day). Other system components include Borets’ 4.56/117 permanent magnet motors (PMM) and Axiom II variable speed drive (VSD) which allows users to have a single VSD capable of running both PMM and induction motors from the same drive and common interface.

“Borets feels the introduction of this cutting edge technology will bring a true step change improvement to the ESP industry for producing unconventional wells,” said Keith Russell, VP of Marketing for Borets. “Having a pump that can produce through the frac cleanup and through what would normally be several pump changes during the initial decline will greatly enhance our customers’ return on investment by lowering costs and optimising the oil produced during this critical period.”

To date, there have been 22 successful field trials of the WR2 system.
