Artificial lift
This paper presents a robust workflow to identify optimization opportunities in gas lift wells through real-time data analysis and a surveillance-by-exception methodology.
To overcome operational constraints tied to ball-and-seat valves, an operator tested a spring-loaded alternative downhole.
Field results highlight how rethinking tubing-anchor-catcher design can reduce gas interference and support late-life production.

SponsoredElectrical 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.
