Claim Text:
1. A method of fracturing an underground geologic formation along a section of a bore hole in the underground geologic formation, the method comprising: positioning a plurality of longitudinally spaced apart explosive charges along the section of the bore hole; and detonating the plurality of longitudinally spaced apart explosive charges with the explosive charges releasing a total energy equal to or greater than twelve kJ/cc and with greater than 30% of the energy released by the explosive being released in the following flow Taylor Wave of the detonated explosive charges; the detonation fracturing the underground geologic formation in a first fracture zone adjacent to and surrounding the section of the bore hole and extending radially into the underground geologic formation to a first radial depth of penetration away from the section of the bore hole, the detonation also fracturing the underground geologic formation in plural second fracture zones longitudinally spaced apart from one another and extending radially into the underground geologic formation to a second radial depth of penetration away from the section of the bore hole greater than the first radial depth of penetration.
