A booster explosive (10) comprises a canister body 12 within which is a cap well (20) having disposed therein a detonator (24). A protective sleeve (28) encloses the cap well (20) except for that portion of the cap well, the active portion (20d), which encloses the explosive end section (24a) of detonator (24). The protective sleeve serves to attenuate the force of shock waves from nearby prior explosions acting on the detonator (24). An annular air space (32) may be provided between protective sleeve (28) and cap well (20) to further attenuate the force of such shock waves. Attenuation of the shock waves reduces the likelihood of damage to detonators (24) by prior nearby explosions.

An explosive device is described herein, wherein the explosive device includes a substrate that has a surface, wherein surface energy of a portion of the surface of the substrate has been modified in a vacuum chamber from a first surface energy to a second surface energy. The explosive device additionally includes explosive material that has been deposited on the surface of the substrate in the vacuum chamber by way of physical vapor deposition (PVD), wherein the explosive material is deposited on the portion of the surface of the substrate subsequent to the surface energy of the portion of the surface of the substrate being modified from the first surface energy to the second surface energy.

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.
