Abstract

The present invention provides an apparatus capable of influencing explosive energy during wellbore applications. In one embodiment, a cap or other interfering element may be arranged proximate to an explosive charge prior to detonation. The size and positioning of the element with respect to the explosive charge may be manipulated to achieve an optimum explosive orientation. A ring element having a bore therethrough may be utilized for directing the explosive energy of the charge upon detonation.
