  • Patent number: 5255750
    Abstract: Hydraulic drilling apparatus and method in which a drill head is driven toward the formation being drilled by the force of the drilling fluid, and the rate of advancement or penetration of the drill head is controlled by entrapping a fluid in a chamber to resist advancement of the drill head and allowing a controlled amount of the entrapped fluid to pass out of the chamber through an orifice to permit the drill head to advance at a controlled rate.
    Type: Grant
    Filed: July 30, 1990
    Date of Patent: October 26, 1993

  • Patent number: 4852668
    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. 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.

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.

  • Patent number: 4715128
    Abstract: 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.

  • Patent number: 4693327
    Abstract: Structure is passed into an earth well including a whipstock attached to piping and a retractible anchor. The whipstock includes a number of connected guide assemblies. Erection means is connected at one end to a forward guide assembly and at the other end to an extension projecting to the earth surface. To erect the whipstock, an extension of the erection means is pulled from the surface to cause the guide assemblies to swing into a curved pathway. Thereafter, a drilling tube is passed through the whipstock into the adjacent formation. The whipstock may be deerected by releasing the extension means. Then, the anchor is released and the structure is pulled out of the well.
