Abstract
An explosive pellet for characterizing a fracture in a subterranean formation is provided. The pellet can include a casing having a detonation material and an explosive material disposed within the casing. The pellet can also include a nonexplosive material moveably disposed within the casing. Movement of the nonexplosive material can generate a predetermined amount of energy in the form of friction-generated heat sufficient to detonate the explosive material.
