  • Patent number: 9488006
    Abstract: A system, method and apparatus for using a tool in a borehole is disclosed. The tool is disposed in the borehole. The tool includes a member rotatable substantially independently of the tool. The member is slidably coupled to a wall of the borehole. The tool is conveyed through the borehole to produce a rotation of the member as a result of the slidable coupling between the member and the wall of the borehole. A parameter of axial motion is determined from an angle of rotation of the member.

  • Patent number: 9316100
    Abstract: A system for making bottom hole assembly (BHA) measurements in the bottom hole assembly (BHA) includes a vibration mechanism configured to use mechanical energy provided by a mechanical energy source to produce a plurality of vibration beats at the BHA. At least one vibration sensor detects the plurality of vibration beats generated by the vibration mechanism. A controller generates a waveform responsive to the detected plurality of vibration beats. The waveform is generated in a first configuration when the BHA has a first weight on bit (WOB) or revolutions per minute (RPM) measurement based on the detected plurality of vibration beats and the waveform is generated in a second configuration when the BHA has a second WOB or RPM measurement based on the detected plurality of vibration beats.

  • Patent number: 8381843
    Abstract: A well bore reamer has an elongated body for coupling between members of a well string, a first set of cutting elements on the body at a fixed position, a second set of cutting elements on a sleeve closing around a sleeve carrying portion of the elongated body. The sleeve is slidable along a longitudinal axis of the body and rotatable thereabout. A lower clutch mechanism operates between the sleeve and the elongated body at a bottom end of the body's sleeve carrying portion to block rotation of the sleeve relative to the elongated body in a predetermined direction about the longitudinal axis under sliding of the sleeve into a lowered position adjacent said bottom end of the sleeve carrying portion.

  • Publication number: 20120199398
    Abstract: A completion system comprises tubular components coupled together to form a completion string. In-flow control devices are provided to permit selective fluid communication between an internal bore of the completion string and the annulus. A reaming tool is provided at a leading end of the completion string and the reaming tool is run into the borehole with the completion string. The reaming tool comprises a fluid-powered drive unit, a reaming body and a reaming nose. In use, the completion string is located in the borehole and fluid is directed to the reaming tool to facilitate reaming of the borehole. A second tubular in the form of a washpipe may extend through an internal bore of the completion string for providing fluid to the reaming tool. The reaming tool is operable at a fluid pressure below a pressure which would activate the in-flow control devices.

  • Patent number: 7168509
    Abstract: A percussive drill bit or reamer having a plurality of bit segments formed into a circular pattern suitable for drilling or reaming a hole. The bit segments are close-fitted and shaped to increase the cutting area and improve efficiency. Pressurized air exhausted from driving the percussion mechanism, or provided from a separate source, is passed into the bit segment and exits from a side face thereof into the gap formed between adjacent bit segments, thereby driving out any debris present in the gap and preventing binding of the bit segments. When utilized with mechanically-driven percussive bit assemblies, where air is only needed to remove debris from a rock face, separately-provided air is delivered to the bit segments of the present invention as described above to clear the gaps of debris.

  • Publication number: 20020139585
    Abstract: A underreamer drill bit assembly including a pilot bit and extendable underreaming arms operatively connected to the pilot bit. The underreaming arms have an extended position for underreaming, and a retracted position in which the overall diameter of the underreamer drill bit assembly is less than the inside diameter of the well casing, permitting the entire bit assembly to be withdrawn through the well casing. In another aspect of the invention, the bit assembly is operatively connected to a dual wall pipe assembly. A supply of compressed air is conducted through the annulus of the dual wall pipe assembly to a down hole pneumatic hammer. Exhaust air from the down hole hammer is directed to the bit assembly for continuous removal of drilling debris through a central evacuation tube of the dual wall pipe assembly. In another aspect of the invention, a pressurized, incompressible fluid is injected into the annulus between the well casing and the downhole pneumatic hammer.

  • Patent number: 6283229
    Abstract: An impact boring tool according to the invention suitable for using with a directional boring machine has a tubular housing and a head mounted at a front end of the housing. The head preferably includes a chisel configured for breaking loose rocks and stones encountered in soil. A striker is disposed within the housing for delivering an impact force to the head, either directly or through one or more intervening parts. A trigger mechanism causes the striker to deliver an impact to the head and chisel only when an external force exerted on the impact tool in its lengthwise direction exceeds a predetermined level. This predetermined level generally coincides with a maximum effective amount of pushing or pulling force for moving the tool through the ground exerted by an external device such as a directional boring machine.

  • Patent number: 4858703
    Abstract: A fluid-operated self-propelled subsoil penetrating tool of the type including an elongated housing member having a penetrating nose portion capable of ejecting a jet of liquid under high pressure to break up and disrupt the subsoil adjacent such nose portion followed by a two-component hammering of such soil to displace and compact same as the tool advances. Remotely-operated steering mechanisms control the path of the tool while remotely-read instruments denote the position, depth, direction and attitude of the tool. A trailing umbilical cord provides all motive and operational fluids and electrical power while transmitting instructions and data between the tool and the remote control station. A unique internal structure reduces the rotation of the tool as it advances and provides for the reverse movement of the tool and electrical supplies through the bore created by the movement of the tool through the subsoil.

  • Patent number: 4732222
    Abstract: In a ram boring machine for laying pipelines without trenching, a double blade that is axially moveable against a compression spring is housed in an impact tip and projects through slots in the impact tip. The double blade is struck by a striker piston and moves, during the breaking-up of an old pipe laid in the ground, substantially independently of the ram boring machine or of its housing. In this way substantially all the impact energy of the piston is used for the benefit of the breaking-up operation.
