Extended Lift Services
High-performance systems for high-rate wells — pumps, motors, drives, sensors, and accessories, engineered end-to-end.
Endurance offers application-specific equipment covering the entire ESP stack. With continuous R&D, we develop innovative tools that create more value for oil and gas production companies. Many of our leading-edge ESP components are undergoing R&D with the exclusive BLAZE® thermal boron diffusion treatment for superior performance in harsh wellbore conditions and extended run life.
Hand-built at our Midland, Texas headquarters using highly engineered components designed for challenging unconventional wells — from induction machines to PMESP® permanent magnet systems.
Hand-built in Midland, TX · Challenging wellbores
Radial and mixed-flow stages assembled into floater-type ESP pumps. Solids-handling designs use the industry's highest-quality bearings and raw materials. Our R&D team is focused on redefining durability expectations — with BLAZE® variants under development for longer run life, reduced horsepower, and greater solids resistance.
Three-phase, two-pole · 3,500 RPM @ 60 Hz
Conventional ESP motors tailored to today's production environment. Rotors, bearings, and shafts assembled in a stator section and protected with a housing. Available in standard and high-temperature variants. Can be installed for a wide operating range or narrowly tailored for a designated production target.
MPS partnership · Synchronous PM motor
The PMESP® system from Magnetic Pumping Solutions integrates a downhole PM motor with the PMVSD® drive. No slip between stator and rotor — proprietary closed-loop control algorithms deliver precision at all speeds and downhole conditions. Step-change in reliability, efficiency, and flexibility.
Ultra-high strength bearings · Oil expansion built-in
Transfers motor torque to the ESP system, balances the pressure differential between wellbore and motor, and allows motor oil to expand/contract with temperature without contamination. Also absorbs the thrust of the ESP system in operation — critical to preserving electrical integrity.
Leading-edge solutions for multi-phase production — critical to ESP system life and reservoir drawdown. Includes our unique mixed-flow handling device for severe slugging, WellWorx partnership tools, and a comprehensive accessories lineup.
Rotary, vortex, mixed-flow · WellWorx partnership
Leading-edge separation for multi-phase production — critical to ESP system life and reservoir drawdown. Rotary and vortex separators plus our unique mixed-flow handling device for severe slugging and high-gas content. Endurance is a WellWorx distribution partner with joint innovations in development. BLAZE® separator components under active lab & field study.
Clamps · Valves · Sand handling · Wellhead feed-through
No 'one size fits all' — we examine every aspect of your well to determine the accessories required. From motor assembly clamps and installation jacks to stainless-alloy check/bleeder valves, tubing drains, gas protective shrouds, and downhole sand handling. Our BLAZE®-treated back pressure control valve has field-tested to 700%+ longer life than conventional.
U.S.-engineered drives, highly engineered cable, and step transformers to connect your field's electrical grid to the pump. Specialized algorithms for both induction and permanent magnet control.
Variable frequency AC · 10–1,500 KVA
U.S.-engineered and manufactured control technology for continuous motor control. Fully enclosed drives with more than 20 control points and alarm methodologies. Distinct algorithms for either induction or permanent magnet motor control. Use the Observer touchscreen to review and update your drive in the field — or access it remotely from the web.
U.S.-manufactured · Deviated & corrosive environments
Highly engineered cable specific to oil-and-gas applications. Cable selection is a major factor in ESP run life — our application specialists help you match armor, insulation, and conductor materials to temperature, pressure, and gas production. Proprietary in-house safety equipment and redesigned spooling trailers make field work faster and safer.
Step-up/step-down transformers · 6, 12, 18, 24-step
The transformer is the robust bridge from your field's electrical grid to your cash flow asset. Leading step-up and step-down transformer offerings in 6-, 12-, 18-, and 24-step arrangements. If your field challenges include managing the grid and harmonics, we can select specialized equipment and filters to improve voltage continuity and results.
24/7/365 optimization and control of your most valuable wellbores. Enterprise-grade security, VSD-native sensors, and a data stream that feeds every layer of the optimization cycle.
24/7/365 control · VSD-native integration
Remote ESP monitoring with real-time control. Our sensors are programmed to communicate with every VSD and report pressure, temperature, and inclination readings. Enterprise-grade security tools ensure your data is transmitted reliably and securely.
Every sensor datum feeds your VSD for closed-loop optimization — and feeds our engineers for condition monitoring, failure prediction, and continuous improvement across your portfolio.
See the Interface platformThermal boron diffusion is currently under R&D across ESP pumps, gas separators, and accessories — future deployments enable longer run life, reduced horsepower requirements, and greater solids resistance in the production stream.
Our application engineers can spec pumps, motors, drives, and accessories tailored to your wellbore.
