Aberdeen-based artificial lift systems firm Zilift has concluded the first field trial of its new magnetic torque technology.
The TorqueDrive system, which the company began developing three years ago, consists of a contactless magnetic torque converter and an equaliser section aimed at progressive cavity pump (PCP) applications in heavy oil operations.
The test was carried out at Zilift’s new facility in Bakersfield, California and was the first known practical demonstration of a magnetic torque converter in a downhole environment, the company claims.
“We believe that TorqueDrive is the most significant advancement in downhole electrical machine design for thirty years,” said Iain Maclean, chief executive of Zilift.
“We have designed a product that, among other benefits, significantly reduces lifetime lifting costs and extends economic production life.
“Our first TorqueDrive variant is well suited to the cyclic steam heavy oil operations in California and, from our base in Bakersfield we intend to provide clients with installation and 24 hour hands on service support.
“We are committed to the region and have confidence in our products and, as we gain sufficient foothold in California, we will look to expand our operations in other North American regions.”
The company will continue field trials throughout this year, targeting future production figures of 400 units from its Aberdeen base.
