Abstract: The present invention relates methods and apparatus for lining a wellbore. In one aspect, a drilling assembly having an earth removal member and a wellbore lining conduit is manipulated to advance into the earth. The drilling assembly includes a first fluid flow path and a second fluid flow path. Fluid is flowed through the first fluid flow path, and at least a portion of which may return through the second fluid flow path. In one embodiment, the drilling assembly is provided with a third fluid flow path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.

Abstract: The present invention provides a liner hanger and a method of hanging a line r in a wellborn. In one aspect, a process for setting a liner in a wellbore is provided in which a tubular (300) having a slip (340) formed on an outer diameter of the tubular at a first location (335) and a preformed bypass (33 0) for circulating a fluid disposed at a second location is set and expanded in to substantial contact with an inner diameter of the wellbore, a casing, or another liner. In another aspect, a process for setting, a liner in a wellbo re is provided in which a tubular having a slip formed on an outer diameter of the tubular at a first location is placed in the wellbore, a bypass for circulating a fluid is formed downhole, the liner is set and expanded into substantial contact with an inner diameter of the wellbore, a casing, or another liner. In yet another aspect, a process for creating, a liner top se al is provided in which the liner is set by expanding a protrusion in an upper end of a tubular into substantial contact with an inner diameter of the wellbore, and the upper end of the tubular is then reformed and expanded int o substantial contact with the inner diameter of the wellbore.

Abstract: The present invention generally relates to a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to methods and apparatus for connecting the tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars. A connector mechanically mates a box end and a pin end of the tubulars together to form the connection. Additionally, mating castellations, surface finishes on the pin end and the box end, torque screws, and a variable pitch groove c an provide resistance to relative rotation between the tubulars at the connection.

Abstract: The present invention generally provides a running tool (100) comprising a torque-dampening system. A first portion (116) and a second portion (118) of the running tool are operably related by a torsion interface (128). In one embodiment, the torsion interface includes a plurality of interlaced teeth (130A,130B) disposed on the each of the first and second portions. During relative rotation of the first and second portions, the teeth engage and "ri de up" on one another, thereby forcing the first and second portions in opposit e axial directions. At least one of the portions houses a flow restrictor assembly (264) adapted to restrict fluid flow from one region to another during the axial movement of the portions. Accordingly, the relative rotatio n between the portions is inhibited, or dampened.

Abstract: A tubular connection 300 has a mateable box portion 205 and pin portion 105. A seal 130 is disposed in a groove 125 formed in the outer surface of the pin portion, wherein the seal is configured to engage an inner surface 230 of the box portion upon mating of the box and pin portions. A bump 135 is formed on an inner surface of the pin portion and is axially aligned with the groove so that the seal remains engaged with the box portion during and after expansion of the box and pin portions. The bump may be constituted by a weld and is preferably curved in cross-section.

Abstract: The present invention generally provides a tubular configured to mate with a second tubular so that sealing integrity is maintained between the tubulars before, during, and after expansion of the tubulars. In one embodiment, a connector for connecting tubulars is provided. The connector includes a pin portion; a box portion, wherein the pin and the box portions are configured to mate; a sealing surfa ce formed in an inner surface of the box portion; a seal disposed in a groove formed i n an outer surface of the pin portion, wherein the seal is configured to engage with a sealing surface of the box portion upon mating of the pin and the box portions; and a bump formed on an inner surface of the pin portion, wherein the bump is substantially axially aligned with the groove and the bump is configured so that the seal remains engaged with the box portion during and after expansion of the pin and the box portions.

Abstract: The present invention generally relates to an apparatus for sealing a wellbore. The sealing apparatus includes an expandable tubular body having o ne or more sealing elements disposed thereon. In one aspect, the sealing elements include swelling and non-swelling sealing elements. Preferably, the swelling sealing elements are made of a swelling elastomer capable of swelling upon activatio n by an activating agent. The swelling elements may be covered with a protective lay er during the run-in. When the tubular body is expanded, the protective layer breaks, thereby exposing the swelling elements to the activating agent. In turn, the swelling elements swell and contact the wellbore to form a fluid tight seal.

Abstract: Embodiments of the present invention relates to hydraulically actuated tools, which may be used to actuate a liner hanger assembly. In one embodiment, the present invention provides a hydraulic setting tool (113) for use in wellbore operations. The setting tool includes a first tubular member (130) and a second tubular member (120) disposed around the outer diameter of the first tubular member. A piston (110) is mechanically attached to an upper portion of the second tubular member and adapted to move axially in relation to the first tubular member. The piston acts to transmit a force to the second tubular member A slip assembly (162) is operatively connected to the second tubular member and the second tubular member transmits the force to the slip assembly thereby actuating the slip assembly.
