摘要： A process is described for milling a window in the casing (2) of an oil or gas producing well, for example in order to drill a lateral well branching off from the main well. A wireline milling tool is first used, in a relatively low cost operation, to create a small window (14) or notch in the casing (2). Provided a small window (14) or notch can be created successfully, an expensive heavy duty coil tubing milling operation can then be conducted to create the full window, some 4-6 feet in length. Previous attempts to create a full window using wireline tools have encountered difficulties due to there being no circulating drilling fluid to remove metal swarf and due to the need for the tool to be supported by casing during the milling operation, when the integrity of the casing is being compromised by drilling the window. The proposed wireline tool has an actuator (4) with relatively small stroke length and a relatively small container (8) to manage the swarf produced by the milling process.

摘要： An offshore well-processing system includes a mobile offshore drilling unit and a remote well-processing device configured to be positioned on an offshore platform different from the mobile offshore drilling unit, the mobile offshore drilling unit defining at least one well centre and comprising at least one primary drill rig including at least one drill floor and at least one hoisting system for raising and lowering tubular equipment through the at least one well centre from/into a well in the seafloor. The mobile offshore drilling unit and the remote well-processing device are configured to be operationally coupled to each other; and the mobile offshore drilling unit is configured to assist in performing concurrent well-processing tasks on respective wells, including the first well processing task performed by the remote well-processing device on a first well and a second well-processing task concurrently performed by the offshore well-processing system on a second well.

摘要： The present invention is directed to a method of salvaging an elongated oil well tubular that extends downwardly from an oil well platform as well as a saw apparatus of improved configuration. The method includes supporting the tubular in a generally upright or vertical position. A cutting apparatus is placed next to the tubular. The cutting apparatus includes a frame that supports a lifting device and a rotary cutter. The lifting device moves the rotary cutter from a first position to a second position that is higher than the first position. The second position is closer to the tubular than the first position. The rotary cutter can travel in an arcuate path when moving from the first position to the second position. The cutter moves along a selected path to cut the tubular. After cutting, the cut section is removed and the tubular then elevated so that an additional cut can be made. This procedure is repeated multiple times until the tubular has been salvaged, cut into many smaller pieces or sections.

摘要： A diamond wire saw and method provides a frame that includes a clamp that attaches to a target (e.g. piling, beam, tubular), an elongated toothed rack extending away from the mount and target, and a moving portion that carries the diamond wire and motor drives that advance the moving portion toward the target and along the toothed rack while driving the wire around roller guides.

摘要： The isolation tool works at depth in the bore of a pipe whose upper end is to be severed and replaced. The tool isolates the lower pipe bore from the upper bore so that flammable downhole fluid is prevented from reaching a welding site along the pipe wall. The tool incorporates: means for establishing a pair of axially spaced apart annular seals engaging the pipe inner surface; means for venting downhole fluid to ground surface; and means for monitoring for seal leakage. The tool is primarily mechanical in nature. It finds use in connection with off-shore platform riser renewal operations.
