Title: Methods and apparatus for removal and control of material in laser drilling of a borehole

Abstract

The removal of material from the path of a high power laser beam during down hole laser operations including drilling of a borehole and removal of displaced laser effected borehole material from the borehole during laser operations. In particular, paths, dynamics and parameters of fluid flows for use in conjunction with a laser bottom hole assembly.

  • The removal of material from the path of a high power laser beam during down hole laser operations including drilling of a borehole and removal of displaced laser effected borehole material from the borehole during laser operations. In particular, paths, dynamics and parameters of fluid flows for use in conjunction with a laser bottom hole assembly.
  • This patent describes a method for determining at least one characteristic of an earth formation penetrated by a borehole and irradiated by radiation. It comprises: positioning a directional radiation sensor in the borehole adjacent to the irradiated formation and rotating the radiation sensor for obtaining a series of successive measurements that are representative of the radiation returning from circumferentially-spaced locations around the borehole; determining the mean as well as the measured standard deviation of the series of successive measurements; and correlating the mean and the measured standard deviation of the successive measurements for providing indications which are representative of themore » one formation characteristic as well as the transverse cross-sectional configuration of the borehole.« less
  • A logging apparatus is described, consisting of an upwardly opening passage in an upper portion of the tubular body for accommodating the lengthwise insertion and removal of an energy radiating source; a chamber in the interior of the tubular body and communicating with the passage for receiving an energy radiating source therein; an energy radiating source means comprising a source and source mount removably positioned in the chamber, the source means including means for removing the source, the removing means comprising an uppermost portion of the source means configured so as to be engagable by a source removing device; andmore » a radiation detector disposed at a location spaced lengthwise from the chamber.« less
  • A borehole survey method and apparatus are claimed for use in drilling substantially horizontal boreholes through a mineral deposit wherein a dip accelerometer, a roll accelerometer assembly and a fluxgate are disposed near the drill bit, which is mounted on a bent sub, and connected to a surface computation and display unit by a cable which extends through the drill string. The dip angle of the borehole near the drill bit, the azimuth of the borehole near the drill bit and the roll angle or orientation of the bent sub are measured and selectively displayed at the surface while themore » drill string is in the borehole for utilization in guiding the drill bit through the mineral deposit along a predetermined path.« less
  • In an apparatus and method of coring a borehole drilled with a rotary rig, the coring or sample-taking projectile will return to the barrel or casing irrespective of how far the projectile enters the formation. A collar in the drill string adjacent the bit contains a number of sample-taking devices and means for firing the devices responsive to a remotely located wave-energy source. The wave energy can be a controlled vibration of the drill string, a radio-wave transmission, or a pressure variation transmitted down the drill mud. One explosive charge fires the coring projectile into the formation while a secondmore » explosive provides positive return. These charges are so arranged that they may be fired at a predetermined time after the first explosion occurs. No retrieval wires or cables are used in the coring device.« less
