Abstract
Various shaped charges and methods of operation produce multiple jets in various profiles by employing multiple initiation points to address various earthen formations and producing different types of perforations in well bores. The shaped charge device includes a configuration of components wherein multiple detonation tracks are used to allow selective initiation and operation. Dual or quad initiation may be provided to initiate operation.
