Abstract
A high percentage of rod pump wells globally experience issues caused by production of a high amount of solids. Premature wear of pump components and stuck pumps are two leading failure modes caused by production of solids. Over the years industry has tried to solve these problems by introducing special coating materials for the wetted parts of rod pumps as well as developing special pump designs. However, currently available sand resistant technologies still lack reliability.
An innovative sucker rod pump with an integral filtering screen was developed and tested to address issues with production of high volumes of solids. This technology allows for increased plunger and barrel run life and has been successfully tested in numerous wells. This paper discusses the details of this new technology and the proven benefits based on field trial results.
