Tracking the multi‐well surface dynamometer card state for a sucker‐rod pump by using a particle filter [PDF]
IET Communications, 2018 For a non‐linear sucker‐rod pumping system, a surface dynamometer card estimation algorithm based on a particle filter is presented. The dynamometer card is a plot of the polished rod load at various positions of a pump stroke. Since the polished rod load measured by a load sensor is frequently affected by drift problems, a local ...
