Abstract
A shaped charge includes a case, an explosive material packed against the inner wall of the case, and a liner for lining the explosive material, where the liner includes Bismuth and Copper powders as constituent elements. The Bismuth element replaces a Lead element which is normally present as a constituent element in prior art shaped charge liners. Bismuth is superior to Lead because all environmental concerns, with respect to the deposition of Lead in a formation, have been eliminated.
