Abstract
A shaped charge for use in perforating formation adjacent a wellbore includes a liner having a substantially non-conical shape (also referred to as bowl-shaped). The liner has first and second layers, with a first layer contacting the main explosive charge. The second layer (made of such materials as copper, silver, gold, and so forth) contributes primarily to formation of a perforating jet while the first layer contains a material that substantially disintegrates upon detonation such that formation of a slug is reduced or eliminated.
