First Claim
Patent Images
1. A method of identifying underperformance of a pumping system, comprising:
- creating a reference composite curve for a parameter of the pumping system;
determining the parameter through actual measurements during operation of the pumping system;
providing a confidence factor based on the methodology of determining the parameter through actual measurements; and
comparing the parameter determined through actual measurements, in conjunction with the confidence factor, to the reference composite curve for identifying underperformance of the pumping system.

Abstract
A system and method are provided for identifying underperformance in a pumping system used to produce a desired fluid. Various conditions are sensed during operation of the pumping system, and those sensed conditions are used to determine measured parameters that are provided with an associated confidence factor. The measured parameters in conjunction with the confidence factors are compared to a reference composite curve for the specific pumping system to determine whether actual performance has satisfied underperformance criteria or moved across a threshold into underperformance.
