Abstract
Methods and systems for performing injection treatments in subterranean formations stimulated by the ignition of propellants are provided. In some embodiments, the methods comprise: igniting a propellant in one or more secondary boreholes in a subterranean formation to at least partially rupture at least a region of the subterranean formation near the secondary boreholes; introducing a fracturing fluid into a first production well bore in the subterranean formation in or near the ruptured region of the subterranean formation at or above a pressure sufficient to create or enhance at least a primary fracture in the subterranean formation that extends into at least a portion of the ruptured region of the subterranean formation; and introducing a displacement fluid into one or more of the secondary boreholes or an injection well bore in the subterranean formation that comprises one or more fractures penetrating the ruptured region of the subterranean formation.
