Abstract
A perforating apparatus that is usable with a well includes a shaped charge. The shaped charge includes a case, an explosive and a liner. The liner is adapted to form a perforation jet to form a perforation tunnel and promote an exothermic reaction inside the tunnel to create a pressure wave to force debris from the tunnel.
