ABSTRACT:
In a gas-generating chemical reaction carried out in a borehole that is largely filled with water, substantial pressure increases can be generated. This pressure can be used to fracture rocks around the borehole and, hence, stimulate water, oil or gas wells in tight rock formations. This pressure increase can also be used to fracture coal seams for enhanced in-situ gasification or methane recovery. This invention discloses the use of a new, novel system, based on the homogeneous reaction of aluminum alkyls with water, to create a controlled pressure increase. The most appropriate reaction mixture, as characterized by the rise of time of the generated pressure pulse and the energy content per unit length of borehole charge, is disclosed in this new invention.
