Abstract: An expandable liner is used to re-complete a wellbore for a re-fracturing operation. The expandable liner may be used to cover the old perforations and provide a larger bore after expansion. The larger bore allows the new completion perforations and fracturing operation to be more easily achieved. In one embodiment, an expandable liner an expandable tubular having a threaded connection, wherein the threaded connection includes a groove configured to fail at a predetermined tension load. In another embodiment, the expandable liner may have a rib disposed around an outer diameter of the expandable tubular, wherein the rib is configured to form a seal with the outer tubular.

Abstract: An improved method and/or apparatus for completing a wellbore is provided. In one embodiment, a method of lining a pre-drilled wellbore is provided. The method includes the act of providing a casing assembly, the casing assembly including a string of casing; and a retractable joint comprising an inner tubular and an outer tubular. The method further includes the acts of running the casing assembly into the pre-drilled wellbore and actuating the retractable joint, thereby reducing the length of the casing assembly through movement between the inner and outer tubulars.

Abstract: Embodiments of the present invention provide apparatus and methods of forming a lateral wellbore wherein the monobore characteristic is maintained. In one embodiment, a method of completing a lateral wellbore comprises inserting a first tubular into a main wellbore; forming one or more oversized portions on the first tubular; and intersecting the lateral wellbore with the main wellbore. The method further includes inserting a second tubular into the lateral wellbore, wherein a portion of the second tubular is positioned adjacent the one or more oversized portions and expanding the portion of the second tubular adjacent the one or more oversized portions.

Abstract: The present invention generally relates to apparatus and methods for completing a well. Particularly, the present invention relates to a single-direction plug for use with cementing applications and with drilling with casing applications. One embodiment comprises a cement plug for installation in a wellbore casing. The plug includes a body and gripping members for preventing movement of the body in a first axial direction relative to the casing. The plug further comprises a sealing member for sealing a fluid path between the body and the casing. The plug is movable in a second axial direction with fluid pressure but is not movable in the first direction due to fluid pressure.
