Patent number: 4991667Abstract: Hydraulic drilling method and apparatus in which the drilling fluid itself is utilized to control the direction in which a hole is bored in the earth. The drilling fluid is discharged through a plurality of forwardly facing nozzles which are inclined at different angles about the axis of the drill head, and the drilling fluid is selectively applied to the nozzles by a rotatable valve member to control the direction in which the hole is cut.Type: GrantFiled: November 17, 1989Date of Patent: February 12, 1991Assignees: Ben Wade Oakes Dickinson, III, Robert Wayne DickinsonInventors: Robert D. Wilkes, Jr., Paul S. Turin, Michael J. Pesavento, Ben W. O. Dickinson, III

Patent number: 4930586Abstract: Hydraulic drilling method and apparatus in which the drilling fluid itself is utilized to control the direction in which a hole is bored in the earth. The orientation of the drill head is monitored by tilt and roll sensors, and the discharge of drilling fluid through radially or obliquely directed nozzles is controlled by poppet valves in accordance with the orientation to control the direction in which the hole is cut.Type: GrantFiled: May 12, 1989Date of Patent: June 5, 1990Assignees: Ben Wade Oakes Dickinson, III, Robert Wayne DickinsonInventors: Paul S. Turin, Robert D. Wilkes, Jr., Rowe Hakes

Patent number: 4852668Abstract: 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. In one embodiment, the fluid is discharged from a central nozzle as a thin wall conical cutting jet, and a plurality of axially directed jets are spaced about the central nozzle for removing material within the circular groove cut by the conical jet. The conical jet can be used without the axially directed jets to cut core samples. In a second embodiment, the discharge nozzle comprises an oblique bore in a rotor which is driven at a relatively slow speed (e.g. 5-50 rpm) by the whirling fluid in the drill head.Type: GrantFiled: January 4, 1988Date of Patent: August 1, 1989Assignees: Ben Wade Oakes Dickinson, III, Robert Wayne DickinsonInventors: Ben W. O. Dickinson, III, Robert W. Dickinson, Sherman C. May, Charles S. Mackey

Patent number: 4790394Abstract: 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: GrantFiled: November 19, 1986Date of Patent: December 13, 1988Assignees: Ben Wade Oakes Dickinson, III, Robert Wayne DickinsonInventors: Ben W. O. Dickinson, III, Robert W. Dickinson, Richard R. Jensen, Sherman C. May, Charles S. Mackey, Robert D. Wilkes, Jr.

Patent number: 4715128Abstract: Probe and method for determining the curvature of an elongated opening such as a borehole in the earth. The probe includes an axially extending flexible shaft and two pairs of sensing wires arranged in quadrature about the shaft for axial movement relative to each other upon bending of the probe. The relative axial positions of the sensing wires on opposite sides of the flexible shaft are monitored to determine the curvature of the borehole.Type: GrantFiled: December 19, 1985Date of Patent: December 29, 1987Assignees: Ben Wade Oakes Dickinson III, Robert Wayne DickinsonInventors: Richard E. Cummings, Charles S. Mackey, Robert W. Dickinson, Ben W. O. Dickinson, III, Merle D. Larsen
