Patent number: 8225878Abstract: An expansion and cementing assembly is run into the well as the expandable liner is made up. A work string is tagged into the expansion assembly and run to depth. Pressure drives the swage to initially expand and move uphole with the attached work string until the liner is expanded above the location of the subsequent cement placement. The assembly is then lowered to engage the guide/float shoe to perform the cementing step. The swage assembly is then released from the guide/float shoe and the balance of the expansion is performed without further expansion against the recently placed cement. The expansion assembly can start at the guide/float shoe or higher, in which case expansion can occur initially in a downhole direction and later be completed in an uphole direction. Variations without cementing are also contemplated.Type: GrantFiled: August 3, 2009Date of Patent: July 24, 2012Assignee: Baker Hughes IncorporatedInventors: Mark K. Adam, Dennis G. Jiral, Lance M.

Publication number: 20110308793Abstract: Casing segments and an expansion cone are positioned and cemented within a new section of a wellbore with a lower casing segment in an overlapping relationship with an upper casing segment. The lower casing segment is radially expanded such that an upper end of the lower casing segment comes into contact with the interior wall of the upper casing segment at the overlap region. The upper casing segment has an inward facing profile at the overlap region that includes a set of wickers that are driven into the lower casing exterior when it is expanded. This forms a metal-to-metal seal between the upper and lower casing segments at the overlap region.Type: ApplicationFiled: June 17, 2010Publication date: December 22, 2011Applicant: VETCO GRAY INC.Inventor: Stephen Paul Fenton

Patent number: 8069900Abstract: Pipe-in-pipe composite tubular structure having between layers a hardenable filling material associating the layers to enhance the structure mechanical performance mostly in collapse. Prior to harden the filling material, the composite tubular structure can be longitudinally deployable between a folded configuration and a deployed configuration, and has a radial dimension increasing between the folded configuration and the deployed configuration. Such structure is well fitted to be used in oil-well downhole structure and casings or underwater pipeline/flowline.Type: GrantFiled: December 10, 2007Date of Patent: December 6, 2011Inventor: Philippe Constant Nobileau

Patent number: 8061423Abstract: An assembly for use in a wellbore formed in an earth formation, comprising an expandable tubular element and an outer structure having first and second portions arranged at a distance from each other, the portions being restrained to the tubular element in a manner that the distance changes as a result of radial expansion of the tubular element, the outer structure further having a third portion arranged to move radially outward upon said change in distance between the first and second portions, wherein said radially outward movement of the third portion is larger than the radially outward movement of the tubular element as a result of radial expansion of the tubular element.Type: GrantFiled: October 1, 2004Date of Patent: November 22, 2011Assignee: Shell Oil CompanyInventor: Wilhelmus Christianus Maria Lohbeck

Patent number: 8061430Abstract: A downhole contraction joint. The downhole contraction joint can include at least one anti-rotation assembly. The anti-rotation assembly can include a first tubular member at least partially disposed within a second tubular member. An axial slot can be formed through at least a portion of the first tubular member, and at least one key can be at least partially disposed within the second tubular member and the axial slot. The downhole contraction joint can also have at least one resetting assembly disposed at a first end of the anti-rotation assembly. The resetting assembly can include a c-ring secured to the second tubular member. The first tubular member can be secured to the lock ring, and the lock ring can be aligned with the c-ring. The downhole contraction joint can also include at least one control line assembly disposed about a portion of the anti-rotation assembly.Type: GrantFiled: March 9, 2009Date of Patent: November 22, 2011Assignee: Schlumberger Technology CorporationInventors: Michael H. Du, Claus Endruhn, David Verzwyvelt

Patent number: 8056641Abstract: A method for radially expanding a tubular element in a wellbore and providing a control line that extends along the tubular element comprises (a) inducing the wall of the tubular element to bend radially outward and in axially reverse direction so as to form an expanded tubular section extending around a remaining tubular section of the tubular element, wherein said bending occurs in a bending zone of the tubular element, (b) increasing the length of the expanded tubular section by inducing the bending zone to move in axial direction relative to the remaining tubular section, wherein said wall includes a material that is plastically deformed in the bending zone during the bending process so that the expanded tubular section retains an expanded shape as a result of said plastic deformation, and (c) extending the control line along the tubular element.Type: GrantFiled: April 21, 2010Date of Patent: November 15, 2011Assignee: Shell Oil CompanyInventors: Petrus Cornelis Kriesels, Pieter Van Nieuwkoop

Publication number: 20110272139Abstract: A system is provided for drilling a borehole into an earth formation, comprising a casing arranged in the borehole, a drill string extending through the interior of the casing to a lower end portion of the borehole, and a body of drilling fluid extending into the casing, the casing having an inner surface susceptible of wear due to frictional contact with an outer surface of the drill string during drilling of the borehole with the drill string. The system further comprises means for reducing wear of the inner surface of the casing, the means including at least one of a hardened layer at the inner surface of the casing, a friction-reducing layer at the outer surface of the drill string, and a lubricating compound contained in the body of drilling fluid.Type: ApplicationFiled: May 15, 2008Publication date: November 10, 2011Inventors: Bernardus Johannes Henricus Van Den Brekel, Grigoriy Grinberg, Matthew Martin Shade, Mark Michael Shuster, Antonius Leonardus Wubben, Djurre Hans Zijsling

Patent number: 8028749Abstract: Apparatus for expanding first and second portions of a downhole tubular in a single trip comprises a support and first and second expansion devices. The first expansion device is mounted on the support and is operable to expand a first portion of tubular. The second expansion device is mounted to a second portion of tubular and is adapted to be engaged by the support following the expansion of the first portion of tubular, and is then used to expand the second portion of tubular.Type: GrantFiled: May 28, 2010Date of Patent: October 4, 2011Assignee: Weatherford/Lamb, Inc.Inventors: Colin McHardy, Simon John Harrall
