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.
