    Abstract: A method of increasing the collapse resistance of a tubular comprises locating a tool having at least one, and typically three, bearing members within a tubular. The bearing members are positioned in engagement with a wall of the tubular to apply a radial force to a discrete zone of the wall. This radial force is then applied to further discrete zones of the wall, the level of radial force being selected such that the collapse resistance of the tubular is increased.

    Abstract: A method of lining a drilled bore comprises running an expandable first tubular (18) into a bore and locating part portion of the first tubular in an unlined section of the bore and another portion of the first tubular (14) overlapping a portion of an existing second tubular. The first tubular is secured (24) relative to the second tubular while retaining the provision of fluid outlets to permit displacement of fluid from an annulus between the first tubular and the bore wall. An expansion device (23) is then run through the first tubular to expand the first tubular to a larger diameter. Cement is then circulated into the annulus between the expanded first tubular and the bore wall. The fluid outlets are then closed.

    Abstract: A method and apparatus for a wellbore assembly. The wellbore assembly may comprise a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline; an accumulator system connected to the conveyance member; and a setting tool connected to the accumulator system. The accumulator system may be configured to supply a fluid pressure to actuate the setting tool. A method of operating a wellbore tool may comprise lowering a wellbore assembly into a wellbore using a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline, wherein the wellbore assembly includes an accumulator system and a setting tool. The method may comprise actuating the accumulator system to provide a fluid pressure to the setting tool. The method may comprise actuating the setting tool using the fluid pressure.

    Abstract: A system compensates for heave induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during MPD, tripping, or when a kick is circulated out during conventional drilling. In one embodiment, a liquid and a gas interface moves along a flow line between a riser and a gas accumulator as the tubular moves up and down. In another embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. In other embodiments, a piston connected with the rig or the riser telescoping joint moves in a fluid container thereby communicating a required amount of the fluid either into or out of the riser annulus. The system also compensates for heave induced pressure fluctuations on a floating rig when a riser telescoping joint located below a RCD is moving while drilling.
