  • Method and apparatus for forming a mono-diameter wellbore casing
    Patent number: 7325602
    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.

  • METHODS FOR EXPANDING TUBULAR STRINGS AND ISOLATING SUBTERRANEAN ZONES
    Publication number: 20080017387
    Abstract: Methods relate to tubulars that may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

  • APPARATUS AND METHODS TO PROTECT CONNECTIONS
    Publication number: 20070267199
    Abstract: The present invention generally relates to a method and apparatus for protecting tubular connections. In one aspect, an expandable tubular connection for use in a wellbore is provided. The tubular connection includes a tubular pin member. The tubular connection also includes a tubular box member having an end portion, wherein the tubular pin member is matable with the tubular box member to form the tubular connection. Additionally, the tubular connection includes a sleeve member disposed on the tubular pin member, wherein the sleeve member is configured to substantially protect the end portion of the tubular box member as the tubular connection is lowered into the wellbore. In yet a further aspect, a method for utilizing a tubular connection in a wellbore is provided.
