Abstract
A perforation tool comprises an explosive charge comprising an explosive focal axis, a tool body containing the explosive charge, and a flowable material carried with the tool and disposed along the explosive focal axis. The flowable material is configured to be released by detonation of the explosive charge and flow to create at least a partial barrier to flow through the aperture in response to the perforation of the tool body by the explosive charge to form an aperture in the tool body.
