Borets introduces PMM-PCP technology to North America
HOUSTON – Borets has conducted a North American field trial of its PMM-PCP system, the first permanent magnet motor (PMM) running at a slow speed without a gear reducer to drive a progressing cavity pump.
The PMM-PCP system ran successfully for Crescent Point Energy in Canada from May 2014 until April 2015 where, during this trial period, the system increased the well uptime from 53.4% to 98.7%, saving Crescent Point substantial workover costs and lost production time.
While previously a conventional induction motor would be run in the well with a mechanical gear reducer to slow the rotating speed of the motor for a progressive cavity pump, PMM motors are equipped with an extremely high power density, which makes the motor 40% shorter and lighter, greatly improved electrical efficiency (18%) and a very flat power factor over a varying load. Additionally, Borets’ cutting-edge PMM-PCP system uses a PMM motor without a gear box to operate a downhole submersible motor between 350 rpm and 750 rpm.
“Deviated or crooked wells that once proved to be a challenge for conventional top driven PCP systems can now be replaced with the innovative PMM-PCP system,” said V.P. of Marketing Keith Russell, Borets.
To date, Borets has successfully installed more than 400 PMM-PCP systems globally, and with the North American introduction of this advanced technology, this positive trend will continue as operators realize the cost savings for challenging wells.
