LESP – the best solution for marginal wells fund


The main reason for downhole equipment failure is contamination by mechanical impurities. The problem of increased removal of mechanical impurities is caused by a small cross-section of Electric Submersible Pump (ESP) working on marginal wells with a nominal capacity of up to 45 m3 per day. There’s another serious problem that can be faced while operating on marginal wells – low efficiency.

Marginal wells fund is characterized by a low efficiency of the equipment, high energy consumption, a shorter service life, and a risk of deviation from the optimal pressure. In this case, a significant part of the wells operates in a periodic mode. There is a gap of efficient technologies that would allow the oil production companies produce liquid in a constant mode with a small production rate and operating time of not less than 600 days, taking into account current complications.

Due to the imperfection of existing technologies for marginal wells fund and low efficiency of such facilities, Triol Corporation has developed an improved method of oil production based on the system of Linear Electric Submersible Pump (LESP). This innovative design is a specially adapted ESP which is driven by PM motor.

LESP provides efficient oil production on marginal wells, thanks to the following technical solutions:

  • Corrosion and wear-resistant design of the pump working parts.
  • Adjusting the production rate in a wide range from 0 to 40 m3 per day.
  • Energy efficiency from 2.2 to 35 kWh / m3.
  • Minimum installation time.
  • Simple start – “one button start”.
  • Installation length – 20 m.
  • Stable operation of the system (monitoring the temperature of the windings, and the position of the slider).
  • Remote monitoring and control modes of the system.

After implementing this complete solution, you will be able to maximize the oil recovery factor for each well, increasing the profitability of the oilfield operation.
