Artificial lift
Sponsored
Electrical submersible pumps (ESPs) are the backbone of artificial lift operations, enabling the extraction of hydrocarbons from challenging reservoirs. However, their effectiveness is often compromised by the extreme downhole environment, characterized by soaring temperatures, high pressures, and exposure to aggressive fluids.
ExxonMobil developed an automated system to identify nonproductive and underperforming Permian Basin wells and prioritize high-volume wells to return to production.
Technology uptake aimed at optimizing resources, delivering consistency, and augmenting what humans can do.
