Abstract: A shaped charge includes a charge case; a liner; an explosive retained between the charge case and the liner; and a primer core disposed in a hole in the charge case and in contact with the explosive, wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid. A perforation system includes a perforation gun, comprising a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises a material soluble in a selected fluid.

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.

Abstract: A system where a group of substantially universal pre-manufactured explosive pellet assemblies are provided for on-site forming of shaped charges. That is, a specifically tailored liner may also be separately provided to the worksite/oilfield and combined with any one of the pellet assemblies so as to form a shaped charge having characteristics that are determined by the particular liner used. In this manner, hazardous shipping of fully assembled shaped charges may be avoided while at the same time allowing the operator a full range of shaped charge performance options based on the availability of uniquely tailored performance determinative liners that are also provided to the oilfield location
