The Industry Challenge:
The performance of electric submersible pumps (ESPs) in oil wells can be impacted by a wide variety of factors including the initial selection of an appropriate system components, the downhole environment, fluid properties and the practices and procedures used by the well operator.
Due to the large number of variables at play, a large set of pump performance data is required to be able to draw statistically significant conclusions.
In most cases, a single operating company does not have enough pump installations to make such conclusions, especially once the pump performance data is sub-divided into wells with similar attributes such as reservoir depth, production rate and fluid properties.
Sharing data among many well operators provides a sufficient set of data to conduct reliable analyses but also introduces variances in measurement units and the terms used to describe the pump performance and failure attributes that make it difficult to compare the data from one operator to the next.
How the JIP helps:
The JIP was initiated in November 1999 to build an online database system to allow operating companies to examine the performance of their pumping systems in comparison to other operators around the world.
The system included a set of standardized terms to describe the pump performance and failure attributes to ensure that data could be compared among operators.
The system also included a number of built-in statistical tools to allow users to perform a wide variety of analyses to better understand the pump performance they were achieving, to learn what equipment selection and operational decisions other operators were making and to monitor the performance of new technologies as they were introduced in the field.
C-FER’s role in the JIP is mainly of a facilitator, a third-party resource working with the participants to ensure that the sharing of information takes place effectively.
C-FER maintains the project’s website, processes the participants’ data to ensure consistency, develops new analysis tools, and conducts a variety of analyses on behalf of the participants.
As of March of 2014, there were about 105,645 ESP records in the system from approximately 758 fields representing 24 operating companies.
In addition to conventional ESP systems, the database includes a number of "non-conventional" ESP's, including subsea, coiled tubing deployed, water source well ESP's, Downhole Oil/Water Separation (DHOWS) ESP systems, and Progressing Cavity Pump (PCP) ESP systems.
