Design features

  • Floating configuration with axial support in the section (optimized for limited content of abrasive particles in reservoir fluid)

  • Floating configuration without axial support in the section (optimized for high concentration of abrasive particles in reservoir fluid)

  • Packet assemble scheme (optimized for severe conditions with high concentration of abrasive particles in formation fluid)

  • Compression configuration (optimized for severe conditions with high temperature of reservoir fluids and with high concentration of solid particles and gas)

Gas separators


Technical characteristics

    4,79
    5,11

  • Body diameter, inch

    3,62
    4,06

  • Formation water supply in working area, bbl per day
    75-3800
    190-3800

  • Separation gas ration

    0,6-0,75
    0,6-0,7

Design features

  • Gas Separators
    - reduce the amount of free gas in the formation fluid at the pump intake;
    - protect from gaslocks appearing;
    - provide stable performance of ESP;
    - Reduces MTBF (minimum time before failure).

  • Dispensers
    - converts reservoir fluid into the homogeneous mixture;
    - eliminates or minimizes the influence of free gas on stages;
    - reduce flow vibration and pulsation in oil well tubing;
    - provides the the pump KPI efficiency;
    - reduce spurging.

  • Gas Separators - Dispensers
    - reduce the amount of free gas;
    - dispense gas inclusions;
    - converts reservoir fluid into the homogeneous mixture at pump intake ;
    - installed in wells with especially high GOR (gas to oil ratio), where nither gas separators, nor the dispensers can't provide stable ESP performance.
