The perforation gun is comprised of a tubular carrier, a charge holder, a plurality of sealed charges, and a detonating cord. The tubular carrier has a length and a plurality of openings. The charge holder has a length and is comprised of a plurality of mounting locations which are each capable of receiving one of the sealed charges. The charge holder is capable of being secured within the carrier. The detonating cord is coupled to at least one sealed charge. In the mounted position and when the charge holder is secured within the carrier, the charges are aligned with the openings in the carrier such that, upon detonation, charge blasts emitted from the charges exit though the carrier openings and perforate a well casing and cement. In one aspect of the invention, the carrier openings are spirally arranged and spaced along the length of the carrier. In still another aspect of the invention, the openings are vertically arranged and spaced along the length of the carrier. In still another aspect of the invention, the carrier is closed at the top and bottom. In still another aspect of the invention, the carrier is capable of capturing debris created by a charge blast emitted from the sealed charges.

I claim: 1. A perforation gun comprising: a tubular carrier having a length, an outer surface, an inner surface, and a plurality of openings, said openings extending from the outer surface to the inner surface such that said surfaces are in fluid communication with one another; a plurality of sealed charges; a charge holder capable of being secured within said carrier, the charge holder being comprised of a plurality of mounting locations, each capable of receiving one of said sealed charges such that said charges, when mounted within said mounting locations, are aligned with the openings in the carrier when the charge holder is secured within the carrier; and a detonating cord having a length, said detonating cord being coupled to at least one sealed charge. 2. The perforation gun of claim 1 wherein said openings are spirally arranged and spaced along the length of the carrier. 3. The perforation gun of claim 1 wherein said openings are vertically arranged and spaced along the length of the carrier. 4. The perforation gun of claim 1 wherein the carrier is closed at the top and bottom. 5. The perforation gun of claim 1 wherein said carrier is capable of capturing debris created by a charge blast emitted from the sealed charges. 6. The perforation gun of claim 1 wherein said carrier is not deformed after detonation. 7. The perforation gun of claim 1 wherein said carrier is reusable. 8. A perforation gun comprising: a tubular carrier having a length, an outer surface, an inner surface, and a plurality of openings, said openings extending from the outer surface to the inner surface such that said surfaces are in fluid communication with one another, wherein said openings are spirally arranged and spaced along the length of the carrier; a plurality of sealed charges; a charge holder capable of being secured within said carrier, the charge holder being comprised of a plurality of plates, said plates being comprised of a plurality of mounting locations, each capable of receiving one of said sealed charges such that said charges, when mounted within said mounting locations, are aligned with the openings in the carrier when the charge holder is secured within the carrier; a detonating cord having a length, said detonating cord being coupled to at least one sealed charge; and wherein said carrier is not deformed after detonation and is reusable.
