  • Patent number: 9689213
    Abstract: A drill string stabilizer has an elongated cavity formed in an exterior surface of the body. An elongated blade is generally disposed to extend from the cavity. The blade is extended or retracted by rotating a stud threaded on opposite ends with left and right handed threads. Rotation of the stud causes axial movement of slide blocks threadingly engaged to the stud. A follower and track between the body and the slide blocks causes the slide blocks to slidingly engage the body. The blade track is inclined relative to the body track so that the blade radially retracts or extends relative to the body as blocks are moved along their respective tracks by rotation of the stud. The position of each stabilizer blade is independent of the other blades.

  • Patent number: 9493998
    Abstract: A drill string tubular component for use in an oil or gas well, in the form of a tubular having a central bore and a mechanism for mobilizing drill cuttings comprising at least one radial impeller (30) configured to apply radial thrust cuttings passing it, the radial impeller being located between first and second axial impellers (10, 20) configured to apply axial thrust to the fluids in opposite directions. Typically helical components of the first and second axial impellers extend in respective opposite directions, typically toward the radial impeller. Fluids are thus diverted radially away from the outer surface of the tubular component, and thereby enter a more turbulent region of the annulus, there reducing the tendency of the drill cuttings to settle out of suspension.

  • Patent number: 8844648
    Abstract: Nearby conductors such as pipes, well casing, etc., are detectable from within a borehole filled with an oil-based fluid. At least some method embodiments provide a current flow between axially-spaced conductive bridges on a drillstring. The current flow disperses into the surrounding formation and causes a secondary current flow in the nearby conductor. The magnetic field from the secondary current flow can be detected using one or more azimuthally-sensitive antennas. Direction and distance estimates are obtainable from the azimuthally-sensitive measurements, and can be used as the basis for steering the drillstring relative to the distant conductor. Possible techniques for providing current flow in the drillstring include imposing a voltage across an insulated gap or using a toroid around the drillstring to induce the current flow.

  • Patent number: 8813873
    Abstract: This invention relates to drilling a well, particularly an oil or gas well, where casing or liner will be installed to stabilize the wellbore. The present invention is intended to permit more drilling and longer lengths of casing or liner to be installed at one time. The present invention includes a combination of a smear tool and specially sized granular lost circulation material solids in the drilling mud which work together to close and seal leaking formations and fractures whether pre-existing or induced by drilling. By the natural collection of the inventive solids along with the conventional particles in the drilling mud to form a filter cake at the problem areas along the wall of the wellbore and the smear tool arranged to compress the filter cake into the problem areas, lost circulation is minimized. Maintaining circulation naturally allows for longer drilling cycles and potentially fewer liner joints in the well.

  • Patent number: 7954566
    Abstract: Apparatus and methods for using the drilling apparatus to increase the linear direction of the drilling action are described. The drilling apparatus contains a drill rod that is fitted with a reinforcing sleeve that is located on the drill rod as close as possible to the drill bit. The outer diameter of the sleeve is configured to be substantially the same as the bit diameter and, if necessary, just slightly smaller than the bit diameter. The sleeve reinforces the drill rod next to the drill bit and reduces and substantially eliminates the gap between the drill rod and the borehole in the vicinity of the drill bit. The sleeve, therefore, reduces the wobble of the drill bit in the borehole and reduces the drill bit from wavering from a straight linear drilling direction. The reinforcing sleeve can contain helical channels for moving material displaced by the drilling process away from the drill bit.

  • Publication number: 20110048803
    Abstract: A rotating drill string sub redistributes wellbore drill cuttings into the drilling fluid flowstream to improve the efficiency of the drilling operation. Standoff elements are located on each side of an agitator, all configured on a relatively short section of drill pipe. The agitator comprises a plurality of alternating blades standing radially outward from and arranged helically about the axis of the sub, and grooves located between pairs of adjacent blades, each groove comprising a flow channel that is open at both ends of the agitator. The standoff elements contain abutment surfaces having an outer diameter greater than the outer diameter of the agitator, so that the agitator is prevented from contacting the wall of the wellbore and therefore does not experience the forces that the standoff elements experience.
