Abstract
A frac plug is configured to seal a pipe of a downhole well. The frac plug includes a cylindrical plug member comprising a glass body made of a tempered or high-compression glass. The plug member has axial opposite ends with a tapered outer diameter surface extending along its length between the ends. The frac plug further includes a seal of compressible material extending substantially around the plug member outer diameter. The seal has opposite axial ends corresponding to the axial ends of the plug member. The seal is movable axially relative to, and compressible against, the plug member outer diameter surface, thus allowing the seal expand radially outward to engage the bore of the pipe. The frac plug is anchored in the pipe bore with clamping portions on axially opposite ends of the plug member. The clamping portion may include bore engagement portions that are arcuate or radially expanding fingers.
