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.
