Abstract
A method and apparatus useful for fracturing subterranean formations with ultra high fluid pressure. The apparatus is capable of producing isolated pressure in a formation surrounding a primary wellbore, sufficient pressure is included within the formation for creating a fracture at the edge of the perforation. The apparatus is comprised of a motor, pump, and nozzle, where the entire apparatus can be disposed within the borehole. The apparatus can be conveyed within the borehole via wireline, coil tubing, slickline, or other tubing. Alternatively, a drill bit can be included for creating the perforation just prior to the fracturing procedure.
