The disclosure relates to perforating systems for perforating the casing of a wellbore. The perforating systems contain insensitive high explosives. The disclosure also relates to shaped charges containing insensitive high explosives for use in such perforating systems. The disclosure further relates to methods of using such perforating systems to perforate the casing of a wellbore.

1. A method of perforating a wellbore, comprising detonating a perforation system in the wellbore to form at least one perforation in the wellbore, wherein the perforation system includes at least one shaped charge, each shaped charge including a first insensitive high explosive, and at least one bo
1. A method of perforating a wellbore, comprising detonating a perforation system in the wellbore to form at least one perforation in the wellbore, wherein the perforation system includes at least one shaped charge, each shaped charge including a first insensitive high explosive, and at least one booster, the at least one booster including a second insensitive high explosive, an anvil, and a flyer plate and detonation causes the anvil to move and strike the flyer plate. 2. The method of claim 1, wherein the perforation is formed in a casing of the wellbore. 3. The method of claim 1, wherein the perforation system further comprises a detonator, and wherein detonating comprises detonating the detonator. 4. The method of claim 3, wherein the detonator additionally comprises a third insensitive high explosive, and wherein detonating the perforation system comprises detonating the detonator, which then results in detonation of the at least one shaped charge. 5. The method of claim 1, wherein the first insensitive high explosive comprises a material selected from the group consisting of triaminotrinitrobenzene (TATB), diamino-trinitrobenzene (DATB), hexanitroazobenzene (HNAB), 3-nitro-1,2,4-triazol-5-one (NTO), and any combinations thereof, and wherein detonating the perforation system comprises detonating the first insensitive high explosive. 6. The method of claim 1, wherein the perforation system further comprises at least one detonator, at least one detonating cord initiator comprising a third insensitive high explosive, and a detonator cord, and wherein detonating the perforation system comprises detonating the detonating cord, which then results in detonation of the at least one detonator and the at least one shaped charge. 7. The method of claim 1, wherein the perforation system further comprises at least one detonator, and wherein detonating the perforation system comprises detonating the at least one detonator, which results in detonation of the at least one booster and the at least one shaped charge. 8. The method of claim 1, wherein detonation causes the flyer plate to form a flat-topped shock wave. 9. The method of claim 1, wherein the flyer plate comprises a curved flyer plate and detonation causes the flyer plate to flatten. 10. The method of claim 1, wherein each booster further comprises an external flyer plate and spacers, and wherein detonation causes the external flyer plate to move. 11. The method of claim 10, wherein the external flyer plate breaks free from the spacers when it moves. 12. The method of claim 1, wherein each shaped charge comprises a main charge comprising a third insensitive high explosive, and wherein the main charge perforates the wellbore. 13. The method of claim 1, wherein the perforation system further comprises a superfine insensitive high explosive with an average particle size of between 1 micron and 50 microns, and wherein detonating the perforation system comprises detonating the superfine insensitive high explosive.
