Abstract

A downhole perforation system includes a ballistic device having an first end and a second end, the ballistic device carrying an explosive material. The system further includes a shock absorption device coupled to at least one of the first or second end of the ballistic device and configured to absorb at least a portion of impact energy produced from detonation of the explosive material. The shock absorption device includes a shock absorption module which includes a viscoelastic body and a rigid structure molded within the viscoelastic body. The rigid structure is configured to break or deform when impacted by a threshold amount of impact energy. Broken or deformed portions of the rigid structure are contained within the viscoelastic body.
