Progressive Cavity Pump controller adjusts speed for fluid production The patented control algorithm of GE’s Lufkin Well Manager™ for Progressing Cavity Pumps varies the pump speed while measuring the amount of fluid produced by the pump. The controller ramps up the pump speed in user-defined steps, with production rates measured at every step to establish a speed-to-production rate relationship. If an increase in speed doesn’t proportionally increase fluid production, the controller slows the speed by steps until desired fluid production is achieved. The control algorithm continues testing the production rate by repeating the speed increase/decrease sequence. Secondary control algorithms slow the pump in case the set point limits have been violated. If the monitored variable remains at an alarm condition when the programmed minimum speed is achieved, the controller will stop the well to prevent equipment damage. Adjust the speed to match reservoir conditions Historical records of the previous 1500 one-minute samples are maintained for process variables including production rate, speed output to the VSD, actual measured speed of the pump shaft, torque and power signals from the VSD.
