PRZ Drillable Cementing (Bridge) Plug (rated operating pressure up to 5076 psi)




It is designed for pressure-tight separation of the casing string intervals.

DESCRIPTION ADVANTAGES:

  • it is used as a cementing or a bridge plug;
  • easy to install by generating excess pressure within the tubing;
  • pressure tightness at the top and at the bottom after installation and retrieval of the setting tool;
  • protection against premature setting of the slips;
  • small length of the drillable area;
  • good drillability of the applied materials;
  • average time to drill out PRZ with a three-cone bit is 6.30 hrs.

FEATURES:

  • the plug has two valves to prevent cement from overflowing from above and below the PRZ installation area;
  • individual design of the slips teeth ensures secure fastening with the casing string and prevents PRZ from rotating while drilling out;
  • allows pressure cementing above PRZ.
