Abstract
A wellbore perforation tool comprises an explosive charge, a tool body containing the explosive charge, and a flowable material carried with the tool. The flowable material is released by detonation of the explosive charge and, after perforation of the tool body by the explosive charge to form an aperture in the tool body, flows to form at least a partial barrier of the aperture.
