  • Method and apparatus for forming a mono-diameter wellbore casing
    Publication number: 20050166388
    Abstract: A mono-diameter wellbore casing. The mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member within a wellbore. A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first tubular member. The second tubular member and the overlapping portion of the first tubular member are then radially expanded again.

  • Liner hanger with sliding sleeve valve
    Publication number: 20050087337
    Abstract: An apparatus and method for forming or repairing a wellbore casing, a pipeline, or a structural support. An expandable tubular member is radially expanded and plastically deformed by an expansion cone that is displaced by hydraulic pressure. Before or after the radial expansion of the expandable tubular member, a sliding sleeve valve within the apparatus permit a hardenable fluidic sealing material to be injected into an annulus between the expandable tubular member and a preexisting structure.
