1PROK-IVE-1 Single-Packer BHA for Wells Operation with Submersible Electric Pump with Simultaneous Isolation of Leak Interval Located Above (rated up to 3626 psi)

It is used for oil extraction with pumps and with simultaneous insulation of upstream leakage interval with water production in the production casing with nominal outside diameter of pipes 140-178 mm.


  • to turn the well back on after a non-production or shutdown period due to a high water-cut of the product, to put the well back to the stock of producing wells; 
  • to develop the well drainage area with the maximum possible output of hydrocarbon reserves;
  • to isolate a water inflow or leak interval in a fast, reliable and cost-effective manner;
  • to avoid expensive remedial works (cost savings up to 1 mln rub.).


  • reliable isolation of the production string leaking section;
  • attachments:
    • safety assembly enables to release the packer in case of complications related to its head padding thus enhancing the safety during workover and emergency works;
    • check flush valve provides conditions for wells production with minimum possible complications and maximum oil flow rate. The valve enables to flush the pump cavity in the course of well production or to treat the pump with various chemical agents;
    • makes the assembly of the BHA possible at subzero temperature of the environment.
