Artificial lift methods are used to operate most of the wells around the world. We design, improve, manufacture, supply, and service advanced artificial lift equipment for any downhole environment. The quality and high reliability of Lex technologies and equipment are confirmed by compliance with the requirements of API, CE and ISO industry standards.
Lex Ultra-High-Speed ESP (UHS ESP™), driven by a permanent magnet motor (PMM) and having an operating speed range from 1,000 to 12,000 rpm, is unrivaled worldwide. Due to its high nameplate operating speed of 10,000 rpm, the length of the UHS ESP™ is 2–3 times shorter than any conventional ESP. The efficiency of the Permanent Magnet Motor exceeds 91%, the use of hard-alloy materials gives our modular pump the abrasion resistance up to 2,000 ppm (2,000 mg/l).
We have improved the standard ESP to enhance the efficiency and reliability of Lex pumps in various well environments. Our engineering team thoroughly analyzes the incoming data to select the optimum efficiency and specific power consumption of each system (formation-wellbore-ESP). As a result, our solutions achieve the maximum efficiency and provide 30-40% runlife increase and 20-50% lower OPEX.
To solve the production problems in wells with the lack of reservoir energy after the gas-lift operation, we have developed the Turbox gas lift pump. The system creates deep drawdown and avoids electricity use in the well by replacing the electric motor with a gas turbine in combination with the innovative Lex Ultra-High-Speed centrifugal pump operating at speeds up to 15,000 rpm.
We develop and continually improve Lex Universal Permanent Magnet Motor (Universal PMM) technology, an alternative way to provide rotational energy for electrical submersible, screw or sucker rod pumps. Lex features a product range of Lex UPMM from 85 to 12,000 rpm operating speeds, high efficiency up to 95%, operational flexibility, lower motor heating rise, stable operation at any frequencies, and high-temperature environments up to 392 °F (200 °C).
SynchroGear™ technology is a drive for sucker rod pumps with up to 98% efficiency. The system integrates power-efficient Universal Permanent Magnet (PM) Motor and smart Variable Speed Drive. Сonventional V-Belt Transmission is not applicable.
To improve production gain from gassy wells, we designed the ESP with a Jet Pump (Jet ESP). The Jet ESP stables the pump operation and increases the drawdown. A Jet pump and UHS ESP™ run in a single completion string are very effective against high gas content, as reducing bottom hole pressure, and gain the well production.
We have developed the upgraded Lex UHS ESP™ that is cable deployed through the 3.5" (89 mm) tubing. The system can quickly resume production in non-operating wells caused by upcoming maintenance or pump failure. Compact UHS ESP™ is riglessly cable-deployed into the tubing through the wellhead. The technology successfully replaces an expensive workover and prevents clogging of the bottom-hole area without killing fluid. The high nameplate operating speed (12,000 rpm) of the ESP and the permanent magnet motor ensure a compact design and easier installation.
