Methods for enhancing the extraction of fluids from subterranean formation through wells using hydrogen produced in-situ. Certain embodiments produce hydrogen in-situ through reactions of a hydride. In one embodiment, at least a portion of the produced hydrogen is retained in the well bore for a sufficient amount of time to allow hydrogen to migrate into the subterranean formation. In certain embodiments, in absorbing the hydrogen, the subterranean formation desorbs and releases certain organic material for production through a well bore. In other embodiments, the subterranean formation is placed under pressure to drive the hydrogen further into the formation and into the molecular structure of the formations and substances contained therein. When pressure is released, the hydrogen creates additional fractures or cracks in the formation through explosive compression, thereby increasing permeability of the formation.
