C-FER Involvement in PCP Systems

C-FER Technologies has been working on various operational and performance issues related to PC pumping systems since 1985.

A field study completed between 1987 and 1989 focused on identifying the effects that wellbore configuration, equipment selection, and operation practices had on the service life of PCP systems. The study also identified several drilling and operational guidelines to mitigate wear related problems in directional and slant wells. A follow up study was initiated in 1990 which included an in depth statistical assessment of operational conditions and wellbore geometry effects on wear related problems and production performance for more than 300 wells.

Through the course of this study, a rudimentary computer model was developed for the design and analysis of PCP systems. This model formed the basis for C-FER's development of PC-PUMP®, a Windows based PCP system modeling and analysis program, that is widely used by both operators and vendors in optimizing the sizing and selection of downhole equipment and surface drive systems for PCP installations.

From 1992 through 1997, C-FER conducted a major joint industry project (JIP) on PCP systems that included several different technical programs encompassing lab tests of PC pumps, elastomers, surface drives and rod string components; various field studies involving the collection and assessment of relevant data for many installations; and various theoretical analyses focused on improving the selection, performance and service life of PC pumps for a range of artificial lift applications. The JIP was sponsored by more than thirty companies representing pump manufacturers and operators from several countries.

Through the JIP, and now on a commercial basis, C-FER has also continued to develop and enhance the capabilities of the PC-PUMP® software.
