Progressing Cavity Pump As A Solution To Increase Productivity of Highly Viscous Oil Wells with Sand Production: A Case Study of Field X

Abstract

Major oil fields in Indonesia have been experiencing massive decline in production, accompanied by excessive sand production that is not beneficial to the integrity of the production system. Sand production has been known to increase the potential of corrosion, reducing lifetime of well equipment, and also known to shut in wells completely due to sand buildup in wellbore. Progressive Cavity Pump has been proposed as a solution to withstand these complications, due to its nature that can handle many types of fluids and even produced solid. The idea is then tested to a mature field X where the majority of the wells have been shut in due to excessive sand problem and low productivity. It is worth noting that after installing the PCP, production started to increase significantly, accompanied by moderate reduce in sand production. Although PCP has proven its effectiveness, it is important to note that auxiliary sand mitigation techniques is required to maintain facilities integrity after several years of production.
