electrical submersible pumps

This paper discusses a new type of mechanical gas separator for electrical submersible pump systems that increases operating flow range and separation efficiency while decreasing erosion problems and improving reliability.

This paper presents an approach using artificial neural networks to predict the discharge pressure of electrical submersible pumps.

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.

This paper explores electrical submersible generator design considerations, theoretical underpinnings, and potential future applications.

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.

A pair of innovative field development strategies are helping tame the wild, wild Permian Basin.

In this second part of a two-part series on advances in artificial lift, we’ll look at the state of optimization and a trio of techniques and technologies under development or new to the market. Look for quarterly reviews of specific types of lift in upcoming issues in the new year.

In this first part of a two-part series, we look at how the artificial-lift sector has adapted to producing unconventional resources. The second part of the series to publish in November will crack open the lift toolbox to take a deeper look at the techniques and technologies under development or new to the market.

The paper presents successful field tests designed to decrease electrical-submersible-pump cooling rates by inducing controlled deadheads rather than shutting down the pumps.
