Abstract
A method for perforating a subterranean formation includes positioning a shaped charge and a reactant composite material in a carrier; positioning the carrier in the wellbore; detonating the shaped charge; and disintegrating the reactant composite material using a shock generated by the detonated shaped charge. The method may also include initiating a first deflagration by using carbon and heat resulting from the detonation of the shaped charge and an oxygen component of the disintegrated reactant composite material. A system for performing the method may include a carrier, a shaped charge positioned in the carrier; and a reactant composite material positioned in the carrier. The reactant composite material may be configured to disintegrate upon detonation of the shaped charge.
