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 expandable liner includes an expandable tubular having a threaded connection and a support layer comprising polyurea disposed around an exterior of the expandable tubular.

Abstract: In one embodiment, a method of completing a wellbore (10) includes positioning an expandable tubular having a support layer (121) disposed on an exterior of the expandable tubular inside a casing (15); mechanically expanding the tubular and the support layer, wherein a distance between an outer diameter of the support layer and the inner diameter of the casing is sufficient to prevent burst of the tubular; and hydraulically expanding the support layer into contact with the casing.

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.

Abstract: A tubular configured to mate with a second tubular so that sealing integrity is maintained between the tubulars before, during, and after expansion of the tubulars is disclosed. In one embodiment, a connector for connecting tubulars is provided. The connector includes a pin portion; a box portion, wherein the pin and the box portions are configured to mate; a sealing surface formed in an inner surface of the box portion; a seal disposed in a groove formed in an outer surface of the pin portion, wherein the seal is configured to engage with a sealing surface of the box portion upon mating of the pin and the box portions; and a bump formed on an inner surface of the pin portion, wherein the bump is substantially radially aligned with the groove and the bump is configured so that the seal remains engaged with the box portion during and after expansion of the pin and the box portions.

Abstract: A locking mechanism for securing a jumper tube to a shunt tube in a well screen assembly for use in gravel packing is disclosed. The jumper tube features a telescoping connector that extends to engage the shunt tube and a locking mechanism that extends the connector the proper distance and then locks the connector into place by engaging lugs that are connected to the jumper tube. Also disclosed is an apparatus and method for securing a connector tube to a well screen assembly using a receiver that is attached to the well screen assembly and is configured to receive a connector tube and secure the connector tube into place with screws. The receiver can be mounted to the well screen assembly via the shunt tube, a top/middle-bottom ring assembly, directly to the base pipe.

Abstract: A method and apparatus for assembling a wellscreen onto a perforated base pipe are provided. The wellscreen defines a tubular body which is suitable for subterranean use in oil, gas, and water wells. In accordance with the present invention, the wellscreen first defines a perforated base pipe having termination members at its opposite ends. Disposed on each termination member is a continuous helical, step-tiered surface. The helical surface serves as a support surface for a layer of filtering material which is rolled around the base pipe. The filtering material is pre-cut to a correct diameter and bias to match the diameters and bias of the spiraling termination support surfaces. The filtering material is connected to the rings to form a substantial seal on the opposite ends. A protective, perforated outer shroud is optionally disposed around the filtering media as well.

Abstract: The present invention provides a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to a method for connecting tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars in a wellbore. More particularly, the present invention provides a tubular connection using a helical or spiral thread insert to seal and maintain mechanical strength in a tubular connection after expansion.
