Abstract (en)

[origin: WO2014167012A1] The present invention relates to a method for hydraulically fracturing a subterranean formation, into which at least one bore is sunk, comprising the method steps of: (a) introducing a fracturing liquid (FL) through the at least one bore into the subterranean formation at a pressure that is greater than the minimum local rock stress in order to create fracturing cracks (FR) in the subterranean formation, wherein the fracturing liquid (FL) contains water and aluminium; and (b) providing a rest phase, in which an exothermic oxidation reaction occurs between the aluminium and the water of the fracturing liquid (FL). The invention further relates to a fracturing liquid (FL) that can be used in the method of the invention.
