  • Method and apparatus for forming a mono-diameter wellbore casing
    Publication number: 20050150098
    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.

  • Method of joining metal oilfield tubulars and well provided therewith
    Patent number: 6860420
    Abstract: A method of interconnecting a pair of metal oilfield tubulars having complementary tapered edges with a common contact surface when the tubulars are interconnected, is provided. The method consist of having a melting temperature lower than the melting temperature of the tubulars, interconnecting the tubulars whereby the think layer of metal is in between the tubulars, applying heat to the thin layer of metal so as to melt the thin layer of metal, and cooling the tapered edges whereby a metallurgical bond is created between the tubulars.

  • Liner hanger with sliding sleeve valve
    Publication number: 20040045718
    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.

  • Lubricant coating for expandable tubular members
    Patent number: 6695012
    Abstract: A lubricant coating (240) for expandable tubulars (215). The interior surfaces of the expandable tubulars are coated with the lubricant coating (240). The expandable tubulars (215) are then placed within a preexisting structure (205). The expandable tubulars are then radially expanded into contact with the preexisting structure.
