Determining pump wear and remaining life from electric submersible pump test curves. [Wear and service life estimation of oil well pumps]

The remaining useful life of an electric submersible pump (ESP) is an important economic consideration in deciding whether the used pump should be returned to service without repair. This paper presents quantitative and qualitative techniques to determine the type and amount of wear that a pump has experienced from analysis of pump test data. This paper discusses methods of categorizing used pumps, depending on the wear and associated performance deterioration. This work also describes failure modes, pump reliability, and the concept of pump (product) infant mortality. The authors show that a used pump can be more reliable and have a longer run life than a new or rebuilt pump. They use test data, tear-down analysis, and a case history to develop these concepts.
