Abstract:
A perforation enhancement cap for a shaped charge contains a shell and a pack of a solid propellant disposed inside the shell. The shell has a tubular straight section and a rounded cap. The rounded cap has a hole. The propellant pack has a through hole. The straight section, the rounded cap, the hole in the rounded cap, as well as the through hole are disposed about a common longitudinal axis. The through hole has a conical frustum section with its larger base facing the inside of the enhancement cap. The enhancement cap is adapted to receive the shaped charge to-form an enhanced perforation charge assembly for perforation and fracturing the formation.

Claim (Index 1):
A perforation enhancement cap for a shaped charge, comprising:\n a shell and a pack of a solid propellant, wherein the shell comprises a tubular straight section with a first end and a second end, and a rounded cap having a hole, wherein the rounded cap is connected to the first end of the tubular straight section, the second end of the tubular straight section is adapted to be coupled with a shaped charge, wherein the propellant pack resides in a cavity formed by the rounded cap and the tubular straight section, and the propellant pack has a through hole in alignment with the hole in the rounded cap, and wherein the tubular straight section, the rounded cap, the hole in the rounded cap, and the through hole are coaxially aligned.
