Mono-diameter wellbore casing

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.

Liner hanger with sliding sleeve valve

An apparatus and method for repairing a wellbore casing (). An opening () in a wellbore casing () is located using a logging tool (). An expandable tubular member () is then positioned in opposition to the opening () in the wellbore casing (). The expandable tubular member () is then radially expanded into intimate contact with the wellbore casing ().
