Abstract
A method and system for downhole operations that includes an energetic material with a reduced sensitivity to temperature, and a temperature rating that is higher than other energetic materials. Downhole tools that use energetic material thus can have a higher temperature rating with the reduced sensitivity energetic material. One embodiment of the energetic material includes an energetic heterocycle compound, such as 2,6-diamino-3,5-dinitropyrazine-1-oxide.
Claims15
A system for subterranean perforating comprising:
- a shaped charge comprising a case, a cavity in the case, and a liner disposed in the cavity;
- a primer assembly disposed in a sidewall of the charge case;
- a detonation cord disposed adjacent the primer assembly;
- an energetic material in the shaped charge, the primer assembly, and the detonation cord, and that comprises 2,6-diamino-3,5-dinitropyrazine-1-oxide;
- and
- a metal jacket encasing the detonation cord.
A method of wellbore operations comprising:
- conducting operations within a wellbore using a perforating system that comprises,
- a shaped charge,
- a detonation cord, and
- a pyrazine compound disposed in the shaped charge and detonation cord;
- and
- initiating detonation of the pyrazine compound in the detonation cord that in turn initiates detonation of the pyrazine compound in the shaped charge.
A system for subterranean perforating comprising:
- a shaped charge;
- a detonation cord disposed adjacent the shaped charge;
- and
- an energetic material in the detonation cord, and that comprises an energetic heterocycle compound.
