1. A shaped charge, comprising:
a case having an interior volume;
an explosive material in the interior volume of the case; and
a liner in the interior volume, wherein the explosive material is between the liner and the case,
wherein the liner is made from a powder complex comprising:
a powdered copper-lead mixture;
a powdered additive complex comprising at least one of a bulk metallic glass composite (BMGC) or a high entropy alloy (HEA) material; and
tracers for distinction and targeted identification wherein the tracers are absorbable in activated carbon or may be free flowing powder or a nano particulate;
wherein, upon detonation of the shaped charge a perforation tunnel is formed in a casing and into a formation in a well, wherein detonation deposits the tracers in the perforation tunnel, and wherein the tracers flow back with production fluid through the perforation tunnel.
