ABSTRACT:
A frangible sealing disk for use downhole in combination with packer components. The sealing disk is a molded ceramic disk having a circular seating face and extending centrally through a dome-shaped seal. The seal is preferred for use in combination with a packer assembly for pressure sealing the borehole, either up hole or down, so that the seal may be broken away easily when it is desired to remove or reset the packer assembly.
