UHS ESP

Lex Ultra High Speed ESP System (LX) utilizes a Permanent Magnet Motor with rotational speeds between 1,000 and 12,000 rpm. Due to its high nameplate operating speed (10,000 rpm), the system has a significantly shorter length for the downhole string (2-3 times less compared against conventional ESP length). The pump has a wider operating range; permanent magnet motors provide high power efficiency (91%), and abrasion resistance (2 g/l) is achieved with hard alloys being applied to the pump along with innovative modular pump design.

Least but not last, LX technology introduces a low footprint Intelligent Drive integrated with a Step-Up Transformer. Developed auto-adaptation algorithms provide significant production gains and ensure maximum efficiency of the system that could not be introduced to the industry in the past, bearing in mind narrow operating speed range of traditional ESPs (2400-4200 rpm).

LX technology may be applied to confront various technological challenges and can provide improved performance and reliability under a range of production and well-fluid conditions, including high GOR, sand production, corrosive environment, commissioning after drilling or frac jobs, etc.

The advantages of Ultra High Speed ESP PMM Systems vs. standard ESP systems:

  • Wide operating range resulting in optimized inventory;
  • Reduced electric power consumption by 30-60% due to the improved efficiency of the whole ESP system;
  • Reduced installation time due to significantly smaller overall diameters and lengths of the system as compared to the conventional ESP;
  • Reduced "human errors" thereby increasing the success of the workover program;
  • Increased reliability through delivery of fully assembled string on well site priorly tested at Lex manufacturing facility;
  • Flexibility at setting depth selection and lower workover costs due to short and slim equipment design.
