Borets – provider of engineering, manufacturing, sales and service for electric submersible pump (ESP) systems – has successfully completed eight North American applications of its Wide Range Wear Resistant (WR2) pump system. The WR2 system is ideally suited for harsh well conditions and has the ability to handle a wide range of production, abrasives and gas with the goal of extending run life and minimizing well interventions.

The initial North American installation was completed on May 15, 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 utilizes 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 stage material is both stronger and harder than traditional ESP stage materials. The stage hardness is 57 HRC which is near the hardness of ceramic bearings and much harder than quartz. The staged is designed for flow rates of 250-1000 bpd (40-160 m3/day) and 560-1900 bpd (90-300 m3/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,” says 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 optimizing the oil produced during this critical period.”

To date, there have been 22 successful field trials of the WR2 system, eight in North America. Several of these applications are currently still running; however, three of the wells that were pulled were capable of passing full API testing following, in one case, a 400-day test period. In addition to the successful installations and the proven ability to operate in challenging conditions, Borets is now operating a new dedicated production facility for this unique stage material.
