Abstract: An expandable tubular member.

Abstract: A method of radially expanding and plastically deforming a tubular assembly comprising a first tubular member, a second tubular member, and a mechanical coupling for coupling the first tubular member to the second tubular member, the method comprising placing the mechanical coupling in tension; and then radially expanding and plastically deforming the mechanical coupling. It is emphasized that this abstract is provided to comply with the rules requiring an abstract to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure; and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims under 37 CFR 1.72.

Abstract: An expandable tubular coupling apparatus includes a first expandable tubular member, a second expandable tubular member, and means for coupling the first expandable tubular member to the second expandable tubular member.

Abstract: An apparatus and method for radially expanding a wellbore using an adaptive expansion system.

Abstract: A radially expandable multiple tubular member apparatus includes a first tubular member and a second tubular member engaged with the first tubular member forming a joint. A sleeve overlaps and couples the first and second tubular members at the joint.

Abstract: Connectors and connections that enhance mechanical and sealing engagement between the ends of tubular bodies that are radially expanded by a forging tool. The connectors are designed to maintain or restore mechanical and sealing engagement following expansion. The connections are made by joining components that exhibit different spring back characteristics following mechanical deformation. Dissimilar material may be used for the connectors or the connected components can be made of the same materials but dimensioned and configured to exert an interfering force between engaged components following expansion. In operation, a material or component with a high spring back characteristic is positioned adjacent a material or component having a lower spring back characteristic. Following passage of a forging tool, the expanded components spring back differently toward their original unexpanded dimensions to produce the enhanced seal or mechanical engagement.

Abstract: A method of forming a wellbore casing within a borehole that traverses a subterranean formation, is provided by assembling a tubular liner by coupling a multi-layer tubular insert assembly to a threaded portion of a first tubular member, and coupling a threaded portion of a second tubular member to the threaded portion of the first tubular member and the multi-layer tubular insert. The tubular liner assembly is positioned within the borehole; and the tubular liner assembly within the borehole is radially expanded and plastically deformed. The multi-layer tubular insert includes a first tubular insert having a first modulus of elasticity; and a second tubular insert coupled to the first tubular insert having a second modulus of elasticity. The first modulus of elasticity is different from the second modulus of elasticity.

Abstract: The surface areas available for absorbing compressive loading of a threaded connection are increased by increasing the engaged area of a torque shoulder in the connection and by reducing the spacing between the stab flanks of the threads. The areas are increased by increasing the dimensions of the components and by decreasing the machine tolerances permitted in manufacturing the components. The gap in the connection adjacent the torque shoulder is reduced so that the contact surface area of the torque shoulder is increased while the close proximity of the surrounding cylindrical walls of the connection reduces voids that can receive plastic deformation of the torque shoulder corners. The surfaces adjacent the torque shoulder are cylindrical in shape rather than being tapered to reduce machining costs and increase the speed of manufacture of the connection.

Abstract: A sealant for an expandable connection. The threaded portions of a pair of expandable tubulars are coated with a sealant. The threaded portions of the expandable tubulars are then coupled. The sealant is cured. The expandable tubulars are then placed within a preexisting structure. The expandable tubulars are then radially expanded into contact with the preexisting structure.

Abstract: Methods and apparatus are provided for obtaining a secure mechanical connection and a pressure-tight seal in the overlapping area of two telescoping tubular bodies. The two bodies, including the overlapping area, are radially expanded to increase the inside diameter of the bodies. The expansion forces an annular seal in the overlapping area into a pressure-sealing engagement between the bodies. A string of pipe assembled from joints secured to each other by telescoping, threadedly engaged expanded pin and box connections may be radially expanded into a surrounding well bore to provide a cased well having an internal diameter greater than the original internal diameter of the pipe string. The seal in the connection comprises an annular elastomeric seal ring and an annular Teflon spacer ring carried in a specially dimensioned groove formed in either the box or the pin, or both members of the connection.
