It is estimated that some two percent of all electrical submersible pumps (ESPs) in the world havesome form of downhole sensor installed. This is a very small sensor population in relation to thenumber of ESPs. Reliable sensor technology has been available for a number of years and yet themajority of ESPs
do not have sensors installed. Part of the reason that sensors are not installed andused more widely is because of the outdated techniques used by ESP manufacturers to diagnose and troubleshoot ESP performance.Operators can use a downhole sensor to obtain a direct measurement of ESP and well performance.
