GALLOP into Late-Life Production: Extending Well Life by Unloading from the Lateral
Objective/Scope:
Presentation will review design, installation, and results of recent novel artificial lift pilot in the DJ Basin.
GALLOP (Gas Assisted Liquid Lift Oscillating Pressure) is a new variant of gas-lift, designed to unload
horizontal wells from the lateral. Unloading from the lateral can add years to a well’s life by preventing
heel loading when reservoir pressure drops too low to keep a well unloaded between the lateral and the
end of tubing.
Methods/Procedures/Process:
Dissolvable Packers: Enabling Day-One Gas Lift and Setting a New Well Control Standard in High-Pressure Wells
In the Delaware Basin, traditional well control during high-pressure annular gas lift installations often introduced risks of formation damage, restricted wellbore access, costly interventions, and extended non-productive time. A dissolvable packer eliminated these drawbacks by delivering reliable pressure isolation without kill fluids, snubbing, or retrieval operations, enabling day-one gas lift.
Enhanced Performance Back‑Check Technology for Gas Lift Valves
Effective back-check performance is critical in gas-lift systems to prevent reverse flow during injection shut-in. As well-integrity requirements strengthen, operators require barrier solutions that do not impede unloading efficiency or gas-lift performance.
Compressor Downtime Mitigation in Gas Lift Operations Utilizing an Automated Compression Optimization System: A Field Study
Compressor downtime remains one of the primary causes of lost production, unstable injection performance, and fugitive methane emissions in gas lift operations. This paper reviews a zero-methane emission compression optimization system designed to stabilize gas lift performance by mitigating gas lift compressor issues, reducing shutdown frequency, and capturing methane emissions.
Reducing Carbon Footprint by Deploying High-Performance Electric Submersible Pumps and Enabling Real-Time Digital Optimization
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 April 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.
What's the Best ESP Design Ever?
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.
