Paper: True Intelligence At The Wellsite

Although the expression only used today, many times it seems the may not be g well operations. This paper will review the features and benefits of a built-in Flux Vector Drive for Beam Pumping. The Flux Vector Technology incorporated in this controller is different from an off-the-shelf Variable Frequency Drives in that it is designed and built for Oil Field Applications and includes application specific software and firmware, which provides the operator with a unique tool that brings a new meaning to te Intelligence. This to control the speed of the pumping unit in each direction of every stroke - in order to meet a pre described pump fill target. The drive also controls rod-force, by slowing or stopping the unit when a predetermined minimum or maximum rod stress is reached. A bridle separation limiter prevents rod float by automatically adjusting the down stroke speed. The gearbox ratio calculator automatically computes the overall ratio between the motor and crankshaft throughout each pump stroke. These features, along with many others included in this Flux Vector Drive, will be reviewed in this paper and case histories will detail actual benefits to the operator.
