ABSTRACT:
A process and apparatus for high pressure drilling are disclosed. The apparatus comprises an essentially solid drill head with horizontally extendable nozzle arms hingedly connected by shear pins thereto. Flow of high pressure fluid both extends the nozzle arms and flows through the nozzle arms, thereby fracturing and shearing material surrounding the drill head. Cessation of fluid flow returns the arms to the vertical position.
