Abstract
Downhole stimulation devices include an energetic material disposed within a housing and an initiator for igniting the energetic material. The initiator may comprise a shaped charge configured to produce a projectile to penetrate the energetic material to ignite the energetic material. The housing of the device may comprise a continuous outer surface. Methods of operating a downhole stimulation device include initiating an energetic material disposed within a housing of the stimulation device in order to burn the energetic material in a laterally extending direction transverse to a depth of a borehole in which the stimulation device is disposed.
