摘要： A method of deploying a jointed tubular string into a subsea wellbore includes lowering the tubular string into the subsea wellbore from an offshore drilling unit. The tubular string has a slip joint. The method further includes, after lowering, anchoring a lower portion of the tubular string below the slip joint to a non-heaving structure. The method further includes, while the lower portion is anchored: supporting an upper portion of the tubular string above the slip joint from a rig floor of the offshore drilling unit; after supporting, adding one or more joints to the tubular string, thereby extending the tubular string; and releasing the upper portion of the extended tubular string from the rig floor. The method further includes: releasing the lower portion of the extended tubular string from the non-heaving structure; and lowering the extended tubular string into the subsea wellbore.

摘要： A method for milling a tubular cemented in a wellbore includes deploying a bottomhole assembly (BHA) into the wellbore through the tubular, the BHA comprising a window mill; and extending arms of the window mill and radially cutting through the tubular, thereby forming a window through the tubular, wherein a body portion of each window mill arm engages and stabilizes from an inner surface of the tubular after a blade portion of each window mill arm cuts through the tubular.

摘要： A mill for use in a wellbore includes a tubular housing having a bore therethrough, a plurality of pockets formed in a wall thereof, and a blade disposed in each pocket. Each blade includes a body having a first side opposite a second side, wherein the first side faces in a direction of rotation of the mill. The blade also includes a blade portion disposed on the first side of the body, wherein the blade portion has a first cutting face stepped relative to a second cutting face. Each blade is movable between a retracted position and an extended position, wherein a portion of the first side and the second side protrude from the housing in the extended position.

摘要： A wellbore cleaning tool for removing irregularities along the inner surface of a wellbore tubular may include a top sub, a cutting assembly, and a bottom sub. The tool is operable to remove irregularities, such as debris, burrs, and jagged edges, along the inside of the wellbore tubular, and thereby provide a clean, inner surface finish. The tool may be actuated into a retracted position, an extended position, and/or a deactivated position.
