Patent number: 9388662Abstract: A settable down hole includes a set of metal slips which include intersecting zones of weakness in the metal which fracture into a large set of pieces during setting of the tool so the pieces can be circulated out of a well without further reduction in size. One zone of weakness is a closed bore passage extending axially through one or more of the slip segments. An expander cone of increased hardness allows an increased angle on the expander cone and slips.Type: GrantFiled: November 8, 2011Date of Patent: July 12, 2016Assignee: MAGNUM OIL TOOLS INTERNATIONAL, LTD.Inventor: W.

Patent number: 9382764Abstract: A system and methodology facilitates conveyance of a tool, e.g. a downhole completion or completion component, via a tool string. The tool string comprises a contraction joint designed to contract if the tool incurs sufficient axial loading. The contraction joint may comprise an outer housing and a mandrel slidably received in the outer housing. The contraction joint also comprises a resettable locking member which selectively releases the mandrel with respect to the outer housing to contract the contraction joint when under sufficient axial loading.Type: GrantFiled: December 20, 2012Date of Patent: July 5, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Henry Phan, John Algeroy

Patent number: 9194206Abstract: A design for a bridge plug wherein the slip elements include an outer contact portion to engage a surrounding tubular member and an inner body portion designed to easily disintegrate during removal of the bridge plug by subsequent milling. The inner body portion is formed of a softer material than the outer contact portion. Also, the inner body portion is made up of a plurality of segments that are readily separated and dispsersed during milling out.Type: GrantFiled: May 19, 2011Date of Patent: November 24, 2015Assignee: BAKER HUGHES INCORPORATEDInventors: Richard Yingqing Xu, Edward O'Malley

Patent number: 9181758Abstract: A latch assembly for a diamond core drill wire line. Included is a cylindrical main body having a main body interior, an outer wall, a main body end and a latch end. A ball hole is defined through the main body. An inner shaft ball lock is contained within the main body. A spring is disposed on the inner shaft ball lock. A main body top is attached to the main body end to contain the inner shaft ball lock within the main body and limit upstream movement of the inner shaft ball lock. A steel ball is then captured between the inner shaft ball lock and the outer wall of the main body such that upon axial movement of the inner shaft ball lock the ball penetrates up through the outer wall to extend past the main body to thereby latch onto an outer tube assembly.Type: GrantFiled: October 17, 2014Date of Patent: November 10, 2015Inventor: Leroy G. Hetager

Patent number: 9163487Abstract: The present invention relates to a device for laying an expansible lining in a conduit. The device may include a patch having an initial diameter less than that of the conduit, and the patch may be configured to deform by radial expansion beyond an elastic limit to an expanded diameter such that it may contact a wall of the conduit. The device may also include an expander tool axially displaceable inside the patch, and the expander tool may be configured to cause the radial expansion of the patch to an expanded diameter. The device may also include a checking member mounted in proximity to the expander tool. A section of the checking member may be calibrated so that the checking member and the expander tool are capable of passing freely inside the patch when the patch is properly expanded, and the checking member and the expander tool are unable to pass inside the patch when the patch is improperly expanded.Type: GrantFiled: October 22, 2010Date of Patent: October 20, 2015Assignee: Saltel IndustriesInventors: James Leighton, Frédéric Nicolas, Yoann Riou, Benjamin Saltel, Jean-Louis Saltel, Gwenaël Tanguy

Patent number: 9085967Abstract: An expansion system including a mandrel slidably coupled to plurality of primary cone segments that are interleaved with a plurality of secondary cone segments. The expansion system has a the first position wherein the primary cone segments and secondary cone segments are in a retracted position, a second position wherein the primary cone segments are in an expanded position and the secondary cone segments are in a retracted position, and a third position wherein the primary cone segments and the secondary cone segments are in an expanded position. When the expansion assembly is disposed within a tubular member and in the second position, the primary cone segments expand the tubular member into a tri-lobe cross-sectional shape.Type: GrantFiled: May 9, 2012Date of Patent: July 21, 2015Assignee: ENVENTURE GLOBAL TECHNOLOGY, INC.Inventor: Frederick Cornell Bennett

Patent number: 9027659Abstract: A technique enables anchoring of a tool in a wellbore. The technique provides traction against a well component without creating high stress concentrations that weaken the well component. An anchoring device comprises anchoring members that are selectively movable to an expanded configuration for anchoring the tool. The anchoring members have traction surfaces able to selectively engage a smooth anchoring surface of the well component at any desired location along the well component. Each traction surface is formed to facilitate traction while minimizing stress concentration.Type: GrantFiled: September 25, 2012Date of Patent: May 12, 2015Assignee: Schlumberger Technology CorporationInventors: Ruben Martinez, Max E. Spencer

Patent number: 9010446Abstract: An anchoring system for use with a downhole tool includes a body with anchor members mounted on the body that pivot radially outward from the body and into engagement with an inner surface of a tubular. Curved slots are provided along a portion of the members and a sliding block has a protrusion that projects into the slots. The slots are curved so that when the block is urged axially within the body, the interaction between the slots and protrusions pivots the members radially outward. A piston is urged through the body to drive the block. Optionally, an elongate helical gear may cooperate with grooves formed in an edge of the members so that rotating the gear pivots the members radially outward.Type: GrantFiled: February 21, 2012Date of Patent: April 21, 2015Assignee: Baker Hughes IncorporatedInventors: Karsten Fuhst, Andreas Peter, Matthias Moeller, Christian Weiner, Ulrich Michael, William Befeld
