Real-Time Detection of Shaft Failures in Electrical Submersible Pumps with Long Short-Term Memory Networks
Electrical submersible pump (ESP) systems are a common form of artificial lift for oil production wells. The ability to detect broken or twisted shafts is critical for optimizing production efficiency of these ESP systems. This problem is particularly relevant in the Permian Basin due to the harsh operating conditions, including sand production, high gas content and frequent pump restarts. This paper presents a deep learning-based approach utilizing Long Short-Term Memory (LSTM) networks to detect shaft failures in ESP systems in real-time.
Alternate Reality: What if it Had Been a Permanent Magnet Instead of an Induction Motor?
ESP permanent magnet motors (PMMs) have been confirmed to conserve power when compared to conventional induction motors (IMs) in various industry papers and studies. However, most production comparisons comprise a snapshot in time or the partial life of a single ESP. This analysis is useful, but it doesn’t convey the full power-saving value of a PMM installation.

Optimizing ESP Designs – Defining Applications For Add-On Components to the Traditional ESP
A thorough set of Electrical Submersible Pump (ESP) data was analyzed to determine the impact of tapered designs and gas handling pumps on the drawdown of wells at varying conditions and the respective run life of the ESP. The operator’s ESP installations are examined, and then normalized for comparative fluid rate targets to evaluate their respective performance post-installation of varying pump designs.
Successful Permanent Magnet Motors Performance on Unconventional Gassy Well Application thru Modern VFD Technology
High volume, high water cut wells historically represent a challenge in terms of economic production, due to limitations with others artificial lift methods, ESPs are usually chosen for this type of application since it can move great volumes of fluid produced by longer laterals being drilled today.
Optimizing ESPs: Gas and Sand Flow Management for Enhanced Uplift
This paper introduces a multi-layered application to tackle two major challenges in unconventional wells within the Permian Basin: gas slugs and high gas-liquid ratios (GLRs) that disrupt electric submersible pump (ESP) operations, and sand fallback during ESP shutdowns, which can cause equipment failures like plugged pumps and broken shafts. These issues reduce efficiency, increase downtime, and drive-up operational costs.
A Safe, Effective, and Economical Approach to Running, Operating and Retrieving ESPs with Permanent Magnet Motors
The installation and retrieval of Electrical Submersible Pumps (ESPs) equipped with Permanent Magnet Motors (PMMs) require robust barriers to prevent shaft rotation and the subsequent generation of voltage. Current methods to provide these barriers involve additional operations, equipment, and personnel, which increase associated risks. This paper introduces a new method that is safe, effective, and economical, improving both safety and operational efficiency during the installation, operation and retrieval processes.
Operating an ESP During a Frac Hit
Most frac hits are significant events with large pressure change, followed by enhanced flow of almost all water then declining with increasing oil at a level higher than before the event. This study examines how best to “ride thru” the frac hit, but also how to manage ESP settings for the rapid fluid rate changes during and after the event. The frac hits occurred at different points in the wells drawdown so The ESP operation was monitored and setpoints adjusted as needed with the changes in load.
Permanent Magnet Motor Risk Assessment in Oil & Gas Operations
In an effort to address safety concerns, PMM manufacturers and operators have worked together and developed API 11S9 Recommended Practice that covers many of the safety issues relative to PMM operations. The PMM is a very good generator due to “always on” permanent magnet rotor so presents a risk of electric shock and arc flash (AF) hazards if rotation occurs when service personnel handle the ESP cable conductors at surface. The primary methods to avoid these hazards is to insure an EquiPotential Zone (EPZ) is created at surface and to shunt the ESP cable leads.
Artificial Lift on the Edge
Artificial lift systems in the oil and gas industry have long relied on Supervisory Control and Data Acquisition (SCADA) technology for monitoring and control. However, as the digital landscape continues to evolve, artificial lift systems must adapt to more dynamic and autonomous operations. In particular, leveraging cloud-native edge computing, microservices, and the Industrial Internet of Things (IIoT) offers the potential to enhance the real-time responsiveness and optimization of artificial lift systems.
