Patent number: 10053954Abstract: A method for reverse circulation cementing of a liner in a wellbore extending through a subterranean formation is presented. A running tool with expansion cone, annular isolation device, and reverse circulation assembly is run-in with a liner. The annular isolation device is set against the casing. A valve, such as a dropped-ball valve, opens reverse circulation ports for the cementing operation. The liner annulus is cemented using reverse circulation. An expandable liner hanger, if present, is expanded into engagement with the casing. The running tool is released and pulled from the hole.Type: GrantFiled: December 11, 2013Date of Patent: August 21, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Arthur Stautzenberger, Richard Noffke, David Matus, Odee Daigle, Ryan Humphrey, Stephen Maddux

Patent number: 9869157Abstract: Reverse circulation cementing of a liner in a wellbore extending through a subterranean formation is presented. A running tool with expansion cone, release assembly, annular isolation device, and reverse circulation assembly is run-in with a liner. The annular isolation device is set against the casing. A valve, such as a dropped-ball operated sliding sleeve valve, opens reverse circulation ports for the cementing operation. The liner annulus is cemented using reverse circulation. The expandable liner hanger is expanded into engagement with the casing. Conventional circulation is restored. The running tool is released and pulled from the hole.Type: GrantFiled: October 9, 2013Date of Patent: January 16, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Emile Sevadjian, Gary Kohn, Arthur Stautzenberger, Richard Noffke, Grant Hartman, Stephen Maddux, Odee Daigle, Ryan Humphrey, David Matus

Patent number: 9828832Abstract: A tool string carrying an external tool, such as a liner hanger, on a release mechanism is lowered into the wellbore. Interlocking lugs and J-slot profile, defined between the exterior surface of the mandrel and interior surface of the release mechanism, allow relative movement of release mechanism and mandrel without releasing the release mechanism. The relative movement allows mechanical operation of a valve or other tool positioned below the release mechanism. Weight-down and rotation of the tool string and mandrel actuates the lower valve assembly by turning a sleeve into alignment with cooperating members of the mandrel. The sleeve, no longer constrained, moves longitudinally in response to a biasing mechanism. Movement of the sleeve allows closure of the valve. After actuation of the valve tool, further weight-down releases the release mechanism from the carried tool.Type: GrantFiled: October 23, 2014Date of Patent: November 28, 2017Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventor: Arthur Stautzenberger

Patent number: 9347278Abstract: A downhole tool assembly is presented for use in a wellbore, the tool having a mandrel assembly for substantially bearing the tensile and rotational loads placed on the tool assembly during run-in to the wellbore, a displacement assembly for substantially bearing displacement loads and for providing relative movement to the mandrel assembly, the displacement assembly for actuating a actuable tool attached to the mandrel assembly. The mandrel assembly has an upper mandrel positioned radially outward of the displacement assembly and a lower mandrel positioned radially inward of the displacement assembly. A load cross-over mandrel transfers the tensile and rotational loads between the upper and lower mandrels. The load cross-over mandrel has a plurality of passages which allow corresponding rods of the displacement assembly to slide therethrough. The rods transfer the displacement loads from actuators above the rods to an actuable tool below the rods.Type: GrantFiled: October 1, 2012Date of Patent: May 24, 2016Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Arthur Stautzenberger, Brock Watson
