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.

What is claimed is: 1. A shaped charge, comprising: a case having an open front end, a closed rear end, an interior and a longitudinal axis; an explosive material disposed in the interior of the case; and a liner disposed over the explosive material; wherein the case includes a first channel extend
What is claimed is: 1. A shaped charge, comprising: a case having an open front end, a closed rear end, an interior and a longitudinal axis; an explosive material disposed in the interior of the case; and a liner disposed over the explosive material; wherein the case includes a first channel extending from an opening on the rear end of the case along the longitudinal axis to an opening in the interior of the case adjacent the explosive material; and a pair of second channels, the pair of second channels having a common opening on the rear end of the case, the common opening being a different opening than the opening for the first channel, the pair of second channels ending in a pair of diametrically opposed openings in the interior of the case adjacent the explosive material, the pair of openings being disposed on opposite sides of the opening of the first channel. 2. The shaped charge of claim 1 wherein the pair of openings are about a same distance from the interior case opening for the first channel. 3. The shaped charge of claim 2 wherein the pair of openings and the interior case opening for the first channel are substantially collinear. 4. The shaped charge of claim 1 further comprising a pair of third channels, the pair of third channels having a common opening on the rear end of the case, the common opening for the third channels being a different opening than the opening for the first channel and the common opening for the second channels, the pair of third channels ending in a pair of diametrically opposed openings in the interior of the case adjacent the explosive material, the pair of openings being disposed on opposite sides of the interior case opening of the first channel and further forward than the pair of interior case openings for the second channels. 5. The shaped charge of claim 4 wherein the pair of interior case openings for the third channels are about a same distance from the interior case opening for the first channel. 6. The shaped charge of claim 5 wherein the pair of interior case openings for the third channel and the interior case opening for the first channel are substantially collinear. 7. The shaped charge of claim 6 wherein the pair of interior case openings for the third channel, the pair of interior case openings for the second channels and the interior case opening for the first channel are substantially collinear. 8. A shaped charge, comprising: a case having an open front end, a closed rear end, an interior and a longitudinal axis; an explosive material disposed in the interior of the case; and a liner disposed over the explosive material; wherein the case includes four channels extending from a common opening on the rear end of the case to four diametrically opposed openings in the interior of the case adjacent the explosive material and the common opening of the rear end of the case is centered on the longitudinal axis, and the four common openings in the interior of the case are circumferentially spaced about 90 degrees apart and are equidistant from the longitudinal axis, and the shaped charge further comprises a fifth channel extending from an opening on the rear end of the case to an opening in the interior of the case adjacent the explosive material, the opening on the rear end of the case being a different opening that the common opening of the four channels, the opening in the interior of the case being centered on the longitudinal axis. 9. A method, comprising: providing the shaped charge of claim 4; and detonating the shaped charge using only one of 1) the opening on the rear end of the case for the first channel; 2) the common opening on the rear end of the case for the second channels; and 3) the common opening on the rear end of the case for the third channels. 10. A method, comprising: providing the shaped charge of claim 8; and detonating the shaped charge using only one of the common opening on the rear end of the case for the four channels and the opening on the rear end of the case for the fifth channel. 11. A shaped charge, comprising: a case having an open front end, a closed rear end, an interior and a longitudinal axis; an explosive material disposed in the interior of the case; and a liner disposed over the explosive material; wherein the case includes a first channel extending from an opening on the rear end of the case along the longitudinal axis to an interior opening in the interior of the case adjacent the explosive material; and a pair of second channels extending from a pair of openings on the rear end of the case to a pair of diametrically opposed interior openings in the interior of the case adjacent the explosive material, the pair of diametrically opposed interior openings of the second channels being disposed on opposite sides of the first channel. 12. The shaped charge of claim 11 further comprising a pair of third channels extending from a pair of openings on the rear end of the case to a pair of diametrically opposed interior openings in the interior of the case adjacent the explosive material, the pair of diametrically opposed interior openings of the third channels being disposed on opposite sides of the interior opening of the first channel and radially outward from the pair of interior openings of the second channels. 13. The shaped charge of claim 12 further comprising a pair of fourth channels extending from a pair of openings on the rear end of the case to a pair of diametrically opposed interior openings in the interior of the case adjacent the explosive material, the pair of diametrically opposed interior openings of the fourth channels being disposed on opposite sides of the interior opening of the first channel, radially outward from the pair of interior openings of the third channels and axially forward from the pair of interior openings of the third channels. 14. The shaped charge of claim 13 further comprising a pair of fifth channels extending from a pair of openings on the rear end of the case to a pair of diametrically opposed interior openings in the interior of the case adjacent the explosive material, the pair of interior openings for the fifth channels being disposed on opposite sides of the interior opening of the first channel, radially outward from the pair of interior openings of the fourth channels and axially forward from the pair of interior openings of the fourth channels. 15. The shaped charge of claim 14 further comprising a pair of sixth channels extending from a pair of openings on the rear end of the case to a pair of diametrically opposed interior openings in the interior of the case adjacent the explosive material, the pair of interior openings of the sixth channels being disposed on opposite sides of the interior opening of the first channel, offset circumferentially about ninety degrees from the interior openings of the second pair of channels and disposed radially outward from the interior opening of the first channel about a same distance as the interior openings for the second pair of channels. 16. The shaped charge of claim 15 wherein the first, second, third, fourth, fifth and sixth channels are substantially parallel. 17. A method, comprising: providing the shaped charge of claim 15; and detonating the shaped charge using at least one of the first channel, the pair of second channels, the pair of third channels, the pair of fourth channels, the pair of fifth channels and the pair of sixth channels. 18. The method of claim 17 wherein the detonating step includes using only one of the first channel, the pair of second channels, the pair of third channels, the pair of fourth channels, the pair of fifth channels and the pairs of second and sixth channels.
