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)
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.
