Publication number: 20140174761Abstract: A shifting tool for use in shifting axial position of a shiftable element in a well. The tool comprises a linkage mechanism configured to translate an independent axial force into a dedicated radial force applied to expansive elements thereof. Thus, the elements may radially expand into engagement with the shiftable element free of any substantial axial force imparted thereon. As such, a more discretely controllable shifting actuation may be attained, for example, as directed from an oilfield surface. Indeed, real-time intelligent feedback may also be made available through use of such elements in conjunction with the noted linkage mechanism.Type: ApplicationFiled: May 7, 2012Publication date: June 26, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Max E.

Patent number: 8678083Abstract: A liner hanger uses a spirally shaped slip member that makes at least one revolution about the mandrel being expanded. The slip member is disposed in a groove with tapered end walls that approach each other during radial mandrel expansion due to shrinkage of said mandrel in the longitudinal direction.

Patent number: 8627885Abstract: A swage is made from segments that slide relatively to each other to go from a run in dimension to a maximum or built dimension when the segments move into alignment. The angle of inclination of the sliding axis between the members is less than the swaging angle for the pipe on the exterior of the segments so that once the segments are aligned and driven into a tubular for swaging they are precluded from extending into misalignment to clear an obstruction. In this manner a minimum drift is provided or the swage simply stalls. The swage in a tubular goes to the predetermined maximum dimension using the sliding surfaces that are at an angle to bear the radial reaction forces from the tubular more directly, thereby reducing the contact forces and the resulting friction. The edge connections reduce bending which can cause segment binding as the swage is built in the tubular.Type: GrantFiled: July 1, 2009Date of Patent: January 14, 2014Assignee: Baker Hughes IncorporatedInventors: Mark K. Adam, Keven M. O'Connor, Jeffrey C. Williams

Patent number: 8356663Abstract: The present invention generally relates to a swage assembly that is movable from a compliant configuration having a first shape to a substantially non-compliant configuration having a second shape. In one aspect, an expansion swage for expanding a wellbore tubular is provided. The expansion swage includes a body and a solid cone disposed on the body. The expansion swage further includes a deformable cone disposed on the body, wherein the solid cone is made from a first material and the deformable cone is made from a second material and wherein the deformable cone is movable relative to the body when the expansion swage is in a compliant configuration. In another aspect, a method of expanding a wellbore tubular is provided.Type: GrantFiled: June 10, 2011Date of Patent: January 22, 2013Assignee: Weatherford/Lamb, Inc.Inventors: Lev Ring, Varadaraju Gandikota, Mike A. Luke, David S. Li

Patent number: 8353354Abstract: A crawler system for an earth boring system comprises at least two expandable tools along a common axis and spaced apart from each other along the common axis by a piston cylinder device. The at least two expandable tools comprise a mandrel comprising a tubular body and an outer diameter, a plurality of blades, and a slidable sleeve capable of manipulating the plurality of blades into collapsed and expanded positions. The plurality of blades of one of the at least two expandable tools expand to an expanded position and engage a borehole wall. The piston cylinder device anchors against the engagement between the borehole wall and one of the at least two expandable tools to axially translate the other of the at least two expandable tools.Type: GrantFiled: July 14, 2010Date of Patent: January 15, 2013Inventors: David R. Hall, Scott S. Dahlgren, Jonathan Marshall

Patent number: 8261818Abstract: A self-inserting seal assembly that sets a seal at a well component to allow for pressure testing of the well component. The seal assembly can be landed on a well component with an ROV. A seal is located on the lower portion of a lower body in the assembly. A set of outer dogs lock with a grooved mating profile formed on the well component to lock the outer housing to provide a reaction point for setting the seal, which may require several thousand pounds of force. A set of inner dogs lock with a grooved mating profile formed on the inner diameter of the outer housing. This locks the lower body to the outer housing to ensure the seal remains set in place. After the well component is pressure tested, the seal assembly can be unlocked and retrieved from the well via an ROV.Type: GrantFiled: May 20, 2009Date of Patent: September 11, 2012Assignee: Vetco Gray Inc.Inventors: Joseph W. Pallini, Rockford D. Lyle, Chii-Ren Lin

Publication number: 20120193088Abstract: A tubular is an expandable compliant anchoring and sealing tubular. In one embodiment, the expandable complaint anchoring and sealing tubular is located on a cladding string, a liner hanger, a packer or a bridge plug. The expandable compliant anchoring and sealing tubular has grooves and protrusions both on external and internal surfaces of the tubular with external protrusions positioned against internal grooves and internal protrusions against external grooves in a radial direction. Upon radial expansion of the expandable compliant anchoring and sealing tubular, the external protrusions may be disposed in high interference contact with the surrounding casing or wellbore providing an anchoring and sealing relationship. This tubular configuration may be used when precise internal diameter of the surrounding casing or wellbore is unknown. The expandable compliant anchoring and sealing tubular may provide dimensional adjustability by bending of the groove spans in a radial direction.Type: ApplicationFiled: September 30, 2011Publication date: August 2, 2012Applicant: MOHAWK ENERGY LTD.Inventors: Scott A.

Patent number: 8230914Abstract: An anchor tool for anchoring a downhole tool within a casing, a well, or any other downhole, hollow space. The tool has a longitudinal tool body with a center axis extending through the tool body in the center of the body, a first recess, a second recess, a third recess, and a fourth recess in the tool body; and a first anchor, a second anchor, a third anchor, and a fourth anchor. The first anchor is provided in the first recess, and so forth, and the anchors are outwards movable in the recesses for anchoring the tool. Each anchor provided in the recesses extends through the tool body transverse to and across the center axis and the anchors and the corresponding recesses are situated in the tool body for providing a symmetrical anchoring of the anchor tool.Type: GrantFiled: April 24, 2008Date of Patent: July 31, 2012Assignee: Weltec A/SInventors: Jørgen Hallundbaek, Rasmus Sommer
