  • Patent number: 9670737
    Abstract: A mud motor has integrated rotatable reamer elements. The reamer elements may be located directly radially outwardly of a rotor of the mud motor on an outer surface of the mud motor. The reamer elements may be applied to provide one or more of sizing a wellbore, smoothing a wellbore and stabilizing a bottom hole assembly and/or drill bit during drilling. The reamer elements may project from pockets formed in an outside surface of the mud motor. Axes of rotation of the reamer elements may be parallel to and/or skewed relative to a longitudinal centerline of the mud motor. Reamer devices that connect at couplings between drill string sections may be used together with the mud motor or applied separately of the mud motor. The reamer devices include inwardly-projecting elements that engage gaps between the drill string sections.

  • Patent number: 9500041
    Abstract: An inground isolator and associated method can provide an electrically isolated break in a drill string using electrical insulating members/isolators that are supported by a housing. During drill string operations, the isolators are subject only compressive forces responsive to both extension (pushing) and retraction (pulling) by the drill string. The isolators can be formed from an electrically insulating material such as a ceramic material. An interchangeable inground tool system is described which integrally serves to provide an electrically isolating gap in the drill string.

  • Patent number: 8807217
    Abstract: A method for using or removing unused rock debris from a bored passageway through subterranean strata using at least one rock breaking apparatus engaged with a conduit string and placed within the subterranean passageway proximal region, using a member adapted to increase the volume of reduced particle size rock debris generated by increasing the frequency of impact and associated breakage of the rock debris inventory, per revolution of the conduit string and/or per volume of fluid slurry circulated. The used volume of rock debris inventory coats the unlined strata wall of said passageway to inhibit strata fracture initiation or propagation, and the unused rock debris inventory is urged from the passageway at an increased rate by the associated reduction in fluid slurry suspension or velocities needed to urge the rock debris through the unlined strata passageway of improved pressure integrity from inhibiting said initiation or propagation of strata fractures.

  • Publication number: 20140166365
    Abstract: Bearing assemblies for downhole tools include a compensator member operatively associated with a slidable member and a bearing member. The slidable member is movable longitudinally relative to the bearing member. Such movement of slidable member occurs when a force acts upwardly on the downhole tool. Thus, the slidable member facilitates absorption of the upward force acting on the downhole tool. During movement of the slidable member, the compensator member is moved from its expanded position to one of its plurality of compressed positions. As a result, the compensator member becomes biased or further biased toward the expanded position. After the upward force dissipates, the compensator member releases some of its stored energy to move from a compressed position toward the expanded position. Longitudinal movement of the slidable member facilitates maintaining engagement of the downhole tool in its working position so that interruptions of operations are minimized.
