Abstract
An apparatus and method for perforating a subterranean formation is disclosed. The apparatus includes a tubular carrier; a charge tube disposed in the tubular carrier; and at least one shaped charge mounted in the charge tube which includes a casing, an explosive material and a liner enclosing the explosive material within the casing. An apex portion of the liner has a cross-sectional thickness greater than a cross-sectional thickness of any other portion of the liner. The cross-sectional thickness of the apex portion may be at least fifty percent thicker than a cross-section of a portion adjacent the apex portion. A density of the apex portion may be greater than the density of any other portions of the liner.
