Detecting mechanical faults on Sucker Rod Pumps at an early, developing stage benefits the reliability and performance of these pumps. In addition, it reduces the risks of environmental damage, as issues are remedied before they become a problem. Traditionally, load cells have been installed to produce a dyno card. For this purpose, the load cell is installed either topside, or downhole. This is expensive, and error-prone, as sensitive sensor equipment is exposed to the harsh conditions in which the pump operates. An alternative solution to produce a dyno card is to use electrical signature analysis (ESA). It is a technology that is based on the analysis of high-frequency electrical signals.
