Abstract

According to some embodiments, a shaped charge inlay may include an upper edge that extends inward and horizontal to an edge of a shaped charge casing associated with a shaped charge. The shaped charge includes an existing liner and the shaped charge inlay further includes a body that extends inward toward an apex of the existing liner. The shaped charge inlay may be disposed above the existing liner in the shaped charge, to disrupt collapse of the existing liner upon detonation of the shaped charge and thereby change the geometry of a perforating jet and resulting perforation created by the shaped charge.
