Speed drive optimizes artificial lift systems

R&M Energy Systems has recently unveiled its Guardian II Variable Speed Drive (VSD), a digital control system for a range of artificial lift systems. The drive system provides continuous feedback of torque, speed, pump efficiency, fluid rate, and estimated down-hole pressure, which it then uses to maintain effective pump control. This level of control protects the rod string and pump from over-torque conditions and helps provide enhanced operational efficiency and higher production, the company states. www.spe.org/jpt
