  • Anti-twist control system for deviated conductor driving systems
    Patent number: 4570717
    Abstract: A system for controlling the deviation of the path of oil or gas well conductor casing at a desired angle, curvature and orientation in the sea bottom stratum through which it is driven from an offshore platform involving the use of conductor guide(s) equipped with longitudinally disposed anti-twist bar(s) fixedly mounted thereon to prevent or arrest any twisting motion along the longitudinal axis of the casing sections which have like, anti-twist bar as the conductor sections are being lowered or driven down from the platform. Motion is arrested by means of the bars on the conductor guide(s) contacting the similar bars fixedly attached to the casing sections being driven through the conductor guides on the platform support structure. By arresting any twisting motion at this relatively elevated point, any undesired twist is minimized in the driven casing sections minimizing any undesired horizontal deviation in the enplacement of the conductor casing which would have otherwise been caused by the twisting.
