Cementing bridge plug STA-CK -118-35


Cementing bridge plugs/sealing element/valve/bypass/round, piston-like slips used in the hydraulic hold-down mechanism prevent the tool from being pumped up the hole of STA-CK series are designed to provide tight separation of cased hole intervals.


  • well remedial and insulation works using bridging material in both: above and below the packer zones;
  • disabling of the water cut reservoirs and their separate intervals with injection of cement compounds in below-packer area;
  • installation of bridges and temporary disabling of reservoir zone;
  • abandonment of wells or conservation of oil reservoir.

Cementing packers of STA-CK series are set by means of installation tool IU-90, which is delivered on Customer's request (one item for 5 installations).
