  • Patent number: 11225840
    Abstract: A pipe assembly has a hollow inner member nested within a hollow outer member. A series of pipe assemblies are connected end-to-end to form a dual-member drill string useful in horizontal directional drilling operations. The drill string has mutually exclusive first and second fluid paths. Fluid seals, interposed between adjacent inner members of the string, isolate the first fluid path from the second fluid path. Compressed air is delivered into the first fluid path from above ground level, and routed to an underground boring tool. The expelled air and spoils are returned to above ground level by way of the second fluid path. One or more baffle elements are supported on the drill string adjacent the boring tool. The baffle elements are configured to prevent compressed air and spoils from flowing between the walls of the borehole and the drill string.

  • Patent number: 11199062
    Abstract: A system, method, and apparatus can identify groundwater as a drilling machine drills a drill hole. Presence or not of groundwater can be continuously monitored as the drilling machine drills the drill hole using one or more groundwater or moisture sensors to detect moisture or water content of cuttings from the drill hole. Such data from the sensor(s) can be processed to determine the presence or not of groundwater and associate the determination with the corresponding location within the drill hole. A mapping or logging of the drill hole can be generated with the location or locations where the presence of groundwater is identified.

  • Patent number: 11199067
    Abstract: The present invention provides a thermally deformable annular packer with pressure relief means for use in oil and gas wells. The annular packer is formed from a stack of component parts, said parts comprising one or more eutectic alloy based ring sections sandwiched between two end sections. At least one of the annular packer component parts has one or more enclosed voids that are configured to become exposed when the packer is subjected to a predetermined pressure or temperature. The exposure of the enclosed voids serves to increase the effective volume within the sealed region formed by the annular packer in the annulus between two coaxial well casing/tubing. The increase in the effective volume serves to reduce the pressure within the sealed region thus preventing a build-up of pressure that might otherwise have damaged the well casing/tubing.

  • Patent number: 11180964
    Abstract: An interlock between a drawworks and a segment hoist includes a sensor for sensing a position of the segment hoist. An interlock signal is generated by the sensor for sensing the position of the segment hoist and is reflective of the position of the segment hoist. A lock operably connected to the drawworks receives the interlock signal and disables operation of the drawworks if the interlock signal meets a predetermined criterion. A method for operating a drill rig includes operating a drawworks to raise and lower a drill string and operating a segment hoist. The method further includes sensing a position of the segment hoist, generating an interlock signal that reflects the position of the segment hoist, and disabling the drawworks if the interlock signal meets a predetermined criterion.
