Methods of fracturing and rupturing rock formations for enhancing heat exchange efficiency in geothermal wells

The disclosure provides for a method of enhancing heat transfer between an injection fluid and a subterranean formation. The method comprises of introducing a fracturing fluid into a first wellbore and a second wellbore comprising a plurality of electro-conductive proppants and electrically controlled propellant, wherein the fracturing fluid is introduced at or above a pressure sufficient to create or enhance one or more primary fractures in the subterranean formation. The method further comprises of applying an electrical current, wherein the plurality of electro-conductive proppants is operable to receive the electrical current and igniting the electrically controlled propellant through application of the electrical current from the plurality of electro-conductive proppants to rubblize the subterranean formation. The method further comprises introducing an injection fluid into the first wellbore, wherein the injection fluid is operable to absorb heat from available surface area from the rubblized subterranean formation.
