Abstract
A technique facilitates perforation, including the perforation of a casing and formation. A shaped charge is formed with a case, a liner, and a high explosive material located between the case and the liner. The liner is formed of a powder material, e.g. a powder metal material. The powder material properties of the liner between an apex of the liner and a skirt of the liner may be selectively varied to provide a desired jet velocity and jet mass of the liner upon detonation of the high explosive material.
