摘要： Embodiments of the present invention generally relate to a joint used with expandable sand screens and other expandable tubulars that permits elongation or contraction of the expandable tubulars during a tubular expansion operation within a wellbore. In one aspect, a connection assembly for use with expandable tubulars is provided. The connection assembly includes a first expandable tubular axially fixable at one end within a wellbore and a second expandable tubular axially fixable at one end within the wellbore. The second expandable tubular has an opposite end adapted to receive an opposite end of the first expandable tubular to provide a joint between the tubulars. The connection assembly further includes a releasable connection between the opposite ends of the tubulars for selectively permitting axial movement of the opposite ends relative to each other. In another aspect, a method for joining a first expandable tubular and a second expandable tubular is provided. Furthermore, a method for substantially eliminating tension or compression forces within an expandable tubular string positioned in a wellbore is provided.

摘要： A packer and method for sealing an annulus in a wellbore is provided. In one aspect the packer comprises a body having one or more conduits formed there-through; a chamber disposed within the body, wherein the chamber is in fluid communication with each of the one or more conduits; and an aperture for pressurizing the chamber. In another aspect, the packer comprises a body having one or more conduits formed there-through; a lock body disposed on a first end of the body; a collapsible member threadably engaged to the body at a first end and shouldered against the lock body at a second end; and a slideable member disposed within the collapsible member. In yet another aspect, the packer comprises a body having one or more conduits formed there-through, wherein the one or more conduits comprises an enlarged first end; and a cutting member disposed with the enlarged first end.

摘要： A method for completing multi-lateral wells and maintaining selective re-entry into laterals is presented. In accordance with the present invention, a first lateral well is drilled from a primary well bore and a string of external casing packers and a packer bore receptacle are run therein. Once the orientation of the packer bore receptacle is determined, an orientation anchor of a retrievable whipstock assembly is mounted thereto. Thereafter, a second lateral well may be drilled. Once the second lateral well is drilled, the whipstock assembly may be retrieved and replaced with a scoophead diverter assembly which also includes an orientation anchor for mating with the packer bore receptacle. At this time, a string of external casing packers may be run into the second lateral well through the scoophead diverter assembly. Finally, a selective reentry tool is run into the scoophead assembly. The selective re-entry tool includes a diversion flapper for selecting either the first or second lateral well bore. Selective re-entry is desirable for the purpose of performing well intervention techniques. The re-entry tool may be actuated by a device located on a coil tubing work string which may be operated from the surface.
