Ultra-High-Speed ESP (UHS ESP™)

Electric Submersible Pump

Ultra-High-Speed ESP (UHS ESP™)

The Lex Ultra-High-Speed ESP (UHS ESP™) is a high-efficiency artificial lift system developed for oil, gas, and geothermal applications. Through advanced motor technology and optimized high-speed pump design, it delivers stable performance across a wide operating range, increases head per stage, and reduces system size, power consumption, and operating costs, even in harsh and high-temperature environments.

Up to 60% power saving

2–3x More Compact Design

20–30 Minute Plug & Play Installation

4x Higher Solids Tolerance

Advanced Well Navigation, handling 3x higher dog-leg severity zones

An average of 1 year of additional continuous runlife

Operating speed adjustments up to 12,000 RPM

Advantages

We developed our innovative PMM-driven Ultra-High-Speed ESP (UHS ESP™) with an operating speed between 1,000 and 12,000 rpm. UHS ESP™ provides effective operation in harsh well conditions, with limited power supply, and below perforation range.

Power Savings

30–60% power saving due to higher overall efficiency

Range & Speed

Efficient operation with unstable inflow due to a wide operating range and speed adjustments between 1,000 and 12,000 rpm

Reduced Cost

Operation in highly deviated wells, optimal tubing depth setting, and reduced well workover cost due to a compact design

30 Minute Installation

Plug&Play design: quick and easy installation within 20-30 minutes

Easy Delivery

Operation in highly deviated wells, optimal tubing depth setting, and reduced well workover cost due to a compact design

Long Runlife

Runlife extended to 1,000-1,500 days in harsh conditions of operation

High resistance

Higher resistance to solids, free gas, high temperature, and corrosive fluids

Overview

Lex Ultra-High-Speed ESP (UHS ESP™) effectively increases well production, power-saving and provides reliable operation in harsh conditions. Before each installation, we analyze the relevant well-specific data and make calculations to inform a customized selection of equipment for every well.

Since 2016, we have installed more than 500 units at offshore and onshore projects worldwide. UHS ESP™ is the world’s first ultra-high-speed ESP system with the broadest operating range of 1,000 through 12,000 rpm and is adaptable to any unstable inflow. High operating frequencies result in 8-16 times more head per stage, 2-3 times shorter length than any conventional ESP and higher overall efficiency. The revolutionary modular design and hard alloys with ceramic friction pairs quadruple the resistance to solids to 2,000 ppm (2,000 mg/l) vs. standard equipment. UHS ESP™ consists of the following components: a modular energy-saving pump, ultra-high-speed submersible Universal Permanent Magnet Motor (Universal PMM) by Lex, high-temperature four-bag seal, rotary gas separator, cooling system, shroud, and Hunter telemetry system. We design and customize equipment packages using both third-party and proprietary software. Unlike conventional equipment, UHS ESP™ is tested and fully assembled at the manufacturing facility. After testing, it is delivered to the site ready for installation, requiring only unloading and MLE connection through the roller on the motor. This means that installing the UHS ESP™ is 3–4 times faster than installing a standard ESP, and the risk of installation error is significantly reduced.

Applications

Deviated wells having extra production potential

Wells having extra production potential and the possibility of installing under the perforated interval, including gassy wells

Wells with higher energy consumption and limited power supply

Low-rate wells down to 50 bblpd (8 m³/day)”

Harsh conditions: highly deviated wells, unstable inflow, low production rate, wells with high free gas content and solids

Remote fields with equipment delivery by helicopters

$Unstable or varying inflow after drilling, hydraulic fracture treatment, or bottom-hole treatment of the well$

Unstable or varying inflow after drilling, hydraulic fracture treatment, or bottom-hole treatment of the well

Application Limits

Min casing size

5.5" (139.7 mm)

Max sand content

2,000 ppm (2,000 mg/l)

Max free gas at intake

75%

Max reservoir temp

302 °F (150 °C)

Note: Operating within these limits ensures optimal performance and equipment longevity.
