The discrete choke is designed to control the fluid flow during oil production and provides discrete setting of the following possible well operation modes:

  • bringing the oil well to the operating mode without interrupting the supply of liquid to the SSHN and ESP lines;
  • establishing of the required well operating mode;
  • taking measurements to determine gas content in the service environment.
  • Meets technical requirements API 6A
