  • Hydraulic drilling apparatus and method
    Patent number: 4790394
    Abstract: Hydraulic drilling apparatus and method suitable for use in a variety of applications including the drilling of deep holes for oil and gas wells and the drilling of vertical, horizontal or slanted holes, drilling through both consolidated and unconsolidated formations, and cutting and removing core samples. The drill head produces a whirling mass of pressurized cutting fluid, and this whirling fluid is applied to a discharge nozzle to produce a high velocity cutting jet. The cutting action is enhanced by abrasive material in the drilling fluid. The direction of the borehole is controlled by controlling the discharge of the drilling fluid either in side jets directed radially from the distal end portion of the drill string which carries the drill head or in a plurality of forwardly directed cutting jets.
    Type: Grant
    Filed: November 19, 1986
    Date of Patent: December 13, 1988
    Assignees: Ben Wade Oakes Dickinson, III, Robert Wayne Dickinson
    Inventors: Ben W. O. Dickinson, III, Robert W. Dickinson, Richard R. Jensen, Sherman C. May, Charles S. Mackey, Robert D. Wilkes, Jr.
