Artificial lift
The accelerating deployment of machine learning and automation is changing the artificial lift landscape. By embedding intelligence into the control loop, operators now can move from reactive decision-making to proactive, continuous optimization.
This paper presents a case study highlighting the demonstration, refinement, and implementation of a machine-learning algorithm to optimize multiple electrical-submersible-pump wells in the Permian Basin.
This paper presents a closed-loop iterative well-by-well gas lift optimization workflow deployed to more than 1,300 operator wells in the Permian Basin.

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.
