Linear ESP SA (Single-acting)

Linear Electric Submersible Pump is an innovational solution for efficient for oil production, especially for wells with flow rate of 0.8-20 m3 / day. The system combines the advantages of linear submersible motor and electric submersible pump, such as compactness, ease of installation and maintenance.

  • intensification of oil production from marginal wells by creating a permanent depression on the reservoir and maintaining optimal dynamic fluid level in the well;
  • operation of the equipment without downtime, in a continuous mode due to the realized capability in control algorithms, to regulate the flow from 0,8m³ to the maximum production rate, when the conditions in the well change;
  • work in inclined and curved wells with a deviation angle from vertical to 40 ° in the suspension zone;
  • increased energy efficiency of oil production in comparison with ESP and SRP by using specially developed algorithms for controlling LESP system;
  • work in wells with a temperature of up to 120C;
  • work with highly viscous fluids up to 3500 cSt;
  • operation with 25% of gas at the reception without an external gas separator due to the built-in gravitational gas separator.
