This case study presents a comprehensive evaluation of how the integration of advanced electric submersible pump (ESP) technologies, efficient gas handling devices, high-efficiency induction motors, and continuous real-time digital surveillance can drive both operational efficiency and sustainability in upstream oil production. The focus is on 22 wells operated by SOGC, Inc. in the Williston Basin, USA, between June 2024 and May 2025.
Distributed Fiber-Optic Temperature Profiling Along Full ESP Systems in Gassy Unconventional Wells
The thermal behavior of Electrical Submersible Pump (ESP) systems deployed in unconventional wells is poorly characterized, particularly when exposed to elevated gas volume fractions and transient flow regimes. Traditional point temperature measurements provide limited spatial resolution and do not capture how gas interference influences heat distribution along pump stages, seal sections, and motors.
Successful Application of the CENesis PHASE™ System to Improve ESP Reliability in Gassy Wells: Case Studies and Lessons Learned
Electric Submersible Pumps (ESPs) face significant performance challenges when free gas enters the system, and bubbles obstruct fluid flow through the pump impellers–a phenomenon known as gas locking, which can induce premature failure. This complication is amplified during gas slug events, which are inevitable in unconventional reservoirs common to the Permian Basin. This paper presents compelling results from real field deployments that highlight superior recovery capabilities achieved through the CENesis PHASE™ Multiphase Encapsulated System.
The Best ESP Design Ever – A Data-Driven Framework For Equipment Selection
This study analyzes a comprehensive dataset of mid-to-late life Electric Submersible Pump (ESP) designs deployed in Delaware Basin wells to identify the most effective configurations for high Gas Volume Fraction (GVF) environments. Downhole GVFs are normalized across wells, and ESP designs are categorized by pump stage count, gas-handling pump type, gas separator configuration, and casing size.
Maximizing Well Production on Tight Casing ESP Applications in the Permian Basin
Electric Submersible Pumps (ESPs) are commonly known in the Artificial Lift Systems for high flowrates capabilities; however, it’s been limited on tight casing application due to not only HP constrains, but also for presenting restriction in terms of chemical treatment all the way down to the bottom of the equipment and reliability concern on tandem motor applications.
Field Evaluation Of ESP Motor Cooling Technologies Deployed In Multizone Permian Wells: Case Studies and Lessons Learned
Electric Submersible Pumps (ESPs) remain one of the most widely deployed artificial lift technologies for maximizing production from Permian wells. Operating companies often find themselves installing ESPs between multiple producing zones or even below the perforated intervals for several reasons, including the goal of maximizing production by setting the pump as deep as possible and increasing natural gas separation to help stabilize operating trends.
Performance Improvements of ESPs using 500 and 700 series PMM in High Demand (High Flow & High HP) applications.
Oil wells utilizing Electric Submersible Pump (ESP) systems require substantial electrical power for continuous operation leading to large operation electrical expenses and inefficiencies in traditional induction motor (IM) setups. This paper presents a comprehensive analysis of integrating Permanent Magnet Motors (PMMs) into ESP configurations to achieve superior power densities and operational efficiencies.
GAS RELEASE SYSTEM BYPASS (GRSB): An Advanced Gas-Handling Technology to Enhance ESP Performance in High-GLR Wells
This paper presents the Gas Release System Bypass, the latest advancement in gas regulation and separation technologies for Electric Submersible Pump systems operating in high-GLR and gas-slugging environments. The GRSB enhances conventional gas-handling methods by integrating the principles of gas regulation, pressurization, centrifugal dispersion, and controlled gas venting through a dedicated bypass system.
Corrosion Mitigation through Automated Corrosion Management and Downhole Design Changes for Annular Gas Lift Wells
The Oxy Texas Delaware North Business Unit (TXDN) experiences frequent premature failures from severe downhole corrosion due to reservoir conditions and chemical undertreatment in wells with <1yr operating life. Typical damage occurs on undertreated annular gas lift wells near cap-string clamps/bands. Turbulent flow occurs on these components from high velocity flowrates, stripping chemical protection for corrosion to develop. From Jan 2022 to May 2025, ~28% of rig work addressed corrosion-induced tubing failures, costing $63.7MM cumulatively.
Overcoming Production Challenges in Oilfields: A Next-Generation Artificial Lift Solution for Complex Well Environments
As the global oil industry increasingly relies on unconventional and marginal assets, operators face a complex array of production challenges. These include high viscosity fluids, significant solid content, gas interference, and the need for deployment in deviated wellbores. Traditional lift methods, such as beam pumping and conventional rotary electric submersible pumps (ESPs), often reach their mechanical or economic limits under these conditions.
