  • Patent number: 11931822
    Abstract: A technique facilitates a welding operation in a variety of difficult environments, including downhole environments, to enable formation of a dependable connection between components. A tool may be constructed to contain a material mixture used in the welding operation. The tool is conveyed to a position adjacent a weld region of components to be welded together. The material mixture is of a type which may be ignited to initiate a reaction which forms a molten metal from at least one constituent in the material mixture. Additionally, the tool comprises a nozzle oriented to direct the molten metal to the weld region so as to form a secure, welded connection between the components.

  • Patent number: 11746613
    Abstract: A device for wellbore operations is configured to self-determine its downhole location in a wellbore in real-time and to self-activate upon arrival at a preselected target location. The device determines its downhole location based on magnetic field and/or magnetic flux signals provided by an onboard three-axis magnetometer. The device optionally comprises one or more magnets. The magnetometer detects changes in magnetic field and/or magnetic flux caused by the device's proximity to or passage through various features in the wellbore. The device can self-activate to deploy an engagement mechanism to engage a target tool downhole from the target location. The engagement mechanism comprises a seal supported by two expandable support rings, each having a respective elliptical face for engagement with the elliptical face of the other support ring.

  • Patent number: 11686175
    Abstract: The invention relates to a method of conducting a perf wash cement (“P/W/C”) abandonment job in an offshore oil or gas well annulus, in particular the washing or cementing operation using a rotating head with nozzles dispensing wash fluid or cement at pressure. A new design of bottom hole assembly is proposed in which the cementing tool has a relatively large diameter in order to optimize pressure whilst the wash tool has a relatively small diameter. The wash process, for a number of reasons, appears to be less sensitive to tool diameter and making the wash tool smaller reduces the overall risk of stuck pipe.

  • Patent number: 11578539
    Abstract: A dissolvable connector allows a wireline or similar conveyance to be detached from a downhole tool or device based on conditions in a downhole environment instead of an external action, such as application of tension or an electrical pulse. The dissolvable connector can be strategically positioned to allow retrieval of expensive tools and equipment that are located above the connector. A protective sheath may be provided around the dissolvable connector that opens or unsheathes based on conditions in the downhole environment (e.g., pressure, temperature), a telemetry signal (e.g., from the surface or from a tool string), or tension, to provide greater control over the timing of the release of the dissolvable connector. Such a dissolvable connector allows the device to be detached from the conveyance without the need for wire-cutting operations or weak-point breaking operations.

Each actuation member comprises a dissolvable plug which in one embodiment is retained by shear pins at an uphole end of a collet sleeve, the latter having radially-outwardly biased protuberances (fingers) which matingly engage sliding sleeves having cylindrical grooves therein, based on the width of the protuberance.

  • Patent number: 10538993
    Abstract: Apparatus and methods for selectively actuating sliding sleeves in sub members which are placed downhole in a wellbore, to open ports in such sub members to allow fracking of the wellbore, or to detonate explosive charges thereon for perforating a wellbore, or both. A simplified dart and sleeve is used which reduces machining operations on each. The dart is preferably provided with coupling means to permit a retrieval tool to be coupled thereto, which upon the retrieval tool being so coupled allows a bypass valve to operate to assist in withdrawing the dart from within the valve subs. Upward movement of the retrieval tool allows a wedge-shaped member to disengage the dart member from a corresponding sleeve to allow the dart to be withdrawn.

  • Patent number: 10450817
    Abstract: A downhole tool that includes a tubular member having a first interior passageway, wherein the first interior passageway defines a first surface having a first internal diameter and a second recessed surface having a second internal diameter that is greater than the first internal diameter. The downhole tool also includes a protective sleeve engaged with the second recessed surface, wherein the protective sleeve has a second interior passageway that defines a third surface having a third internal diameter that is substantially equal to the first internal diameter such that the third surface is substantially flush with the first surface. In one embodiment, the protective sleeve is dissolvable upon contact of a fluid having predetermined composition or predetermined temperature such that the sleeve dissolves to expose the recesses formed in the latch assembly.
