  • Patent number: 11187068
    Abstract: A downhole tool can be advanced downhole a wellbore. The downhole tool can include an electromagnetic source, a directional antenna, and a casing. The casing can either completely or partially consist of ceramic materials. The directional antenna can be oriented to direct electromagnetic radiation generated by the electromagnetic source towards the ceramic materials of the casing. In response to receiving the electromagnetic radiation, the ceramic materials can absorb the electromagnetic radiation, which can cause the ceramic materials to rapidly increase in temperature.

  • Patent number: 11149509
    Abstract: A drill pipe assembly has an inner tubular member with a Trojan central bore. An outer tubular member circumscribes the inner tubular member. An annular storage space is defined between the outer tubular member and the inner tubular member. An uphole connection member connects to an uphole drill string so that the Trojan central bore is in communication with the uphole drill string. A downhole connection member connects to a downhole drill string so that the Trojan central bore is in communication with the downhole drill string. A window assembly is moveable between a closed position and an open position. In the open position the window assembly provides a flow path between the annular storage space and an outside of the outer tubular member. In the closed position the window assembly prevents a flow between the annular storage space and the outside of the outer tubular member.

  • Patent number: 10975633
    Abstract: The present invention is a modification of U.S. Pat. No. 9,416,601 that is incorporated herein as if fully set forth. Once the tool is secure to the tubular, axial translation of the driving nut to the “locked” position prevents selective grip or release. A slot cut in the driven nut and in the surrounding housing allows additional right hand rotation so that a lug is captured on a shoulder to prevent subsequent axial compression of the selective grip assembly, where the tubular grip will be maintained with rotation. By preventing the tool from moving to the “unlocked” position when set down weight from the rig as applied, it can be operated in a variety of common conditions in today's well drilling environments with applied tension or compression as well as rotation in a direction that leaves the lug captured on a ledge adjacent the slot cut in the driven nut.

    Abstract: A float collar tool for running a casing string assembly into a wellbore includes a non-fragmenting rupture disc that temporarily isolates light fluid trapped in a lower portion of the casing string from heavier fluid in the upper portion of the casing string, thereby reducing the horizontal weight of the casing string by an amount sufficient to overcome a drag force. After the casing string is landed at a final location in the wellbore, the rupture disc is burst by increasing fluid pressure in the upper portion of the casing string. The increased pressure activates a piston that then moves the burst rupture disc into a protective region of the tool so that the inside diameter of the casing string is substantially restored.

  • Patent number: 9945196
    Abstract: The articulated wireline hole finder is a modular device which attaches to the bottom of a wireline logging tool-string to aid conveyance down irregular shaped and/or deviated boreholes which possess features such as ledges, washouts, and contractions, that might otherwise terminate full descent of the tool-string to the bottom of the borehole and thereby compromise the wireline data acquisition objectives. Elements of the articulated wireline hole finder may include a low friction roller nose assembly and spacer sub, an articulated spring joint, that transfers tool-string weight and directs lateral movement of the roller nose towards hole center, and a pair of five arm centralizers that possess a wide dynamic range.

  • Patent number: 9859693
    Abstract: Described is a device (410) for use in removing a conveyance member from a material. The device (410) includes a displacement element (412) for being placed at least partly around a conveyance member and for displacing material as the device is advanced along a conveyance member. The device (410) also includes a driven component for receiving a driving force for driving the device through material. The device can include a coupling element (418) for coupling the device to a shaft and a material loosener (414) including a drilling element. The material loosener can be operable to loosen material ahead of the displacement element as the device is advanced along a conveyance member. The drilling element can be coupled to a first wheel (436) and the coupling element can include a second wheel (434) cooperating with the first wheel to transfer rotational movement of a shaft to the drilling element.

  • Patent number: 9777568
    Abstract: A bipartite sensor array comprising two portions capable of assembly into a single sensory system. A first portion includes rigid bodies connected by elongate flexures and fitted with gravimetric tilt sensors. The elongate flexures are capable of non-monotonic and non-constant bend in two degrees of freedom. A second portion includes rigid bodies connected by joints, contains the first portion. The second portion, which may be delivered and assembled separately from the first, provides rigidity and protection, enabling the first portion to have short rigid bodies and long connecting flexures, thereby reducing the number of sensors required. The bipartite sensor array is applicable to geotechnical measurements of soil and civil structures.

  • Patent number: 9593536
    Abstract: A casing drilling system includes combination conduit of a casing and a pipe inside the casing. A first adapter has a flow diverter to redirect at least flow of drilling fluid returning from a bottom of a wellbore to either an interior of the pipe or an annular space between the casing and the pipe. A second adapter has a flow diverter to redirect flow of drilling fluid into the conduit through the other one of the interior of the pipe and the annular space. The second adapter has a fluid connection between either the interior of the pipe or the annular space and a rotationally fixed fluid outlet. The system includes a casing chuck having means to support the casing and a slidable conduit operable to expose an uppermost end of the casing and a connection between the second adapter and an uppermost end of the pipe.
