Artificial lift
Unlike traditional AI approaches that rely primarily on historical data, physics-based AI integrates physical laws, engineering expertise, and operational constraints directly into the learning process. Three recent SPE papers illustrate how this paradigm is transforming the industry through intelligent condition monitoring, virtual sensing, and autonomous production …
This research focuses on combining physics-based expert rules with machine learning to improve the detection of failure-related events in electrical submersible pumps.
A combination of physics principles and machine-learning techniques is used in this work to develop a virtual flowmeter for oil-production optimization in electrical-submersible-pump-lifted oil wells, resulting in reliable generalization.

The authors of this paper present an artificial-lift timing and selection work flow using a hybrid data-driven and physics-based approach that incorporates routinely available pressure/volume/temperature, rate, and pressure information. -
Paper SPE 213089 describes an artificial lift selection tool for unconventional reservoirs driven by reduced-physics models. Paper SPE 213975 extols the value of gas lift downsizing by optimizing the selection and placement of Venturi, orifice, and dummy valves. And Paper SPE 214361 explains how electrical submersible pumps could become electrical submersible generato…
