Abstract
A disclosed example embodiment includes a shaped charge for use in a well perforating system. The shaped charge includes a housing having a discharge end and an initiation end. A liner is positioned with the housing. A main explosive is positioned within the housing between the liner and the initiation end of the housing. The liner has a radially outwardly disposed concave section having a progressively decreasing wall thickness in the direction from the initiation end to the discharge end of the housing and a radially inwardly disposed convex section having a progressively increasing wall thickness in the direction from the initiation end to the discharge end of the housing such that the liner is radial momentum balanced and operable to form a coherent jet having a hollow leading edge following detonation of the shaped charge.
