YAKPRO-CPG-1 Anchor BHA for well operation with ESP units

YAKPRO-CPG-1 Anchor BHA for well operation with ESP units

It is designed for operation of the wells with high gas ratio well fluid with submersible pump equipment. It allows to operate with the closed tubing using APG gaslift effect for production strings with nominal outside diameter of 140 (5 1/2")-178 mm (7").

  • to reduce pumping unit vibration;
  • to extend the overhaul period of the submersible pump;
  • to reduce production costs;
  • to ensure a more complete output of the reserves from a well drainage area;
  • to reduce load on tubing;
  • to perform direct flushing of ESP unit.


  • allows to operate wells with such gas factors values at which submersible pump units cannot operate in a continuous mode;
  • reduces the bringing out of the mechanical rock particles from a formation together with well fluid;
  • excludes hydrate plugging of the passages in Xmas tree especially in autumn and winter period;
  • increases the formation fluid flow rate due to APG gaslift effect;
  • extends the overhaul period of a well due to the reduced vibration of the pump unit.
