(2024040) Sucker-Rod Pump Selection and Application

The most common form of artificial lift is sucker-rod pumping. One of the main elements of rod lift system design is the selection of a downhole pump. This study examines the various factors that affect the selection and design of downhole rod pumps. This paper will examine the following five downhole pump components: barrel, plunger, cages, balls and seats, and seating assembly. Understanding the various well and system design factors that are examined when selecting each of these components is a crucial part in the design of the downhole pump. The dynamics that affect metallurgy, length, diameter, and pump configuration of the critical components are examined within this study. Once the aspects that affect material selection have been evaluated the different applications of API and specialty pumps are considered. By following the procedures and methodology outlined in this study, proper downhole pump selection can be implemented and the risk for premature pump failures is mitigated.
