1PROK-UOA-1 Stand-alone Single-packer BHA for Well Pumping Used to Reduce the Water-Cut of Produced Fluid (rated up to 5076 psi)



1PROK-UOA-1 Stand-alone Single-packer BHA for Well Pumping Used to Reduce the Water-Cut of Produced Fluid (rated up to 5076 psi)

It is applied in oil production using ESP unit with water-repellent treatment of the bottom-hole area of the well and avoidance of well-killing fluid entering the bottom-hole formation zone in production strings with nominal outside diameter of pipes ranging from 140 (5 1/2")-219 mm (8 5/8”).

BHA APPLICATION ALLOWS

  • to decrease the water-cut percentage of the well fluid down to 10-30% and enhance oil production (an engineering calculation is needed);
  • to carry out development with maximum output of hydrocarbons due to applying water-repellent treatment of bottom-hole area;
  • to monitor the pump operation parameters and bottom-hole pressure by the dynamic level during the well production;
  • to avoid well-killing fluid contact with bottom-hole area during workover activities of downhole pumping equipment replacement.

ADVANTAGES

  • enables to carry out direct and reverse flushing of the pump cavity during the well production;
  • operation of the wells with high gas ration;
  • disconnection assembly enhances the safety of workover and emergency activities.
