Artificial lift
Honorees Rajan Chokshi and Mike Poythress say the guidance they received, and later shared with others, helped shape decades of innovation and leadership in artificial lift.
As digital technologies become commonplace, industry leaders say core engineering knowledge remains essential for making informed decisions and avoiding costly mistakes.
While equipment run life and reliability remain core concerns, experts say operators are increasingly turning to real-time surveillance and autonomous optimization to unlock new production gains.

The papers described here focus on novel unconventional horizontal downhole pump card signatures, carbon reduction through alternative energy to pump wells, and predicting downhole-discharge pressure of ESPs. -
The world of artificial lift has witnessed a remarkable revolution over the past 25 years, with many of the events and technology trends recorded in the Journal of Petroleum Technology.

This article describes how Oxy developed an in-house application to handle critical production operations tasks including surveillance, optimization, downtime entry, and well testing. The application, called Nexus, allows well analysts and production engineers to manage twice the number of wells they were able to manage just 5 years ago.

The authors of this paper discuss the effectiveness of smaller port sizes and the use of dummy and Venturi valves to enhance gas lift performance and maximize recovery in mature offshore fields.
-
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…

This paper presents a proposed condition indicator that estimates the wear experienced by an all-metal progressing cavity pump at any point in operation and takes into consideration the effects of downhole operating conditions.
