Abstract
A frac plug is configured to seal a bore of a pipe of a downhole well. The frac plug comprises a generally cylindrical plug member comprising a glass body. The glass body may be tempered or high-compression glass. The plug member has axial opposite ends and a length extending between the axial ends. The plug member has an outer diameter surface extending along the length. The outer diameter surface is tapered. The frac plug further comprises a seal of compressible material extending substantially around the plug member outer diameter. The seal has opposite axial ends generally corresponding to the axial ends of the plug member. The seal is movable axially relative to the plug member outer diameter surface. The seal is compressible against the plug member outer diameter surface and expandable radially outward to engage the bore of the pipe.
