Abstract
By using reactive shaped charges, a dynamic underbalance effect associated with detonation of a perforating system is enhanced without compromising shot density. Fewer shaped charges can be loaded to achieve the same or better effective shot density as a gun fully loaded with conventional shaped charges, thereby increasing the free volume within the gun while creating debris-free tunnels with fractured tips and substantially eliminating the crushed zone surrounding each perforated tunnel. Further, the strength and grade of gun steel required to construct the gun can be reduced without compromising the amount the gun swells following detonation.
