Patent number: 11454096Abstract: The present disclosure relates generally to downhole tubulars, and more particularly, to tubular expanders for downhole tubulars that have a detachable expansion ring, which can be detached from the tubular expander in the event that full expansion cannot be achieved or the tubular expander should get stuck in the downhole tubular being expanded. The detachable expansion ring may be attached to an end of an expansion cone that is disposed within a main body of the tubular expander. Tubing hangers are one exemplary downhole tubular device which can be expanded using the tubular expander in accordance with the present invention.Type: GrantFiled: April 25, 2019Date of Patent: September 27, 2022Assignee: TIW CorporationInventors: Peter T.

Patent number: 10337298Abstract: A liner hanger seals with casing string 8 having mill scale and supports a liner 98 within a well. The liner hanger includes a tubular anchor 48 and a tubular expander 40. The tubular anchor 48 may be positioned in the casing string 8 using an inner mandrel 10. An actuator assembly 6 forcibly moves the tubular expander 40 into the tubular anchor 48, expanding the tubular anchor 48 to grippingly engage the expanded tubular anchor 48 against the casing string 8 and to form a circumferential seal between metal sealing elements 52 on the tubular anchor 48 and the interior wall of the casing string 8. The metal sealing element 52 is oversized to provide rigidity, heat shrunk onto the tubular anchor 48, and abrasively dressed to remove excess material prior to installation of the liner hanger.Type: GrantFiled: October 5, 2016Date of Patent: July 2, 2019Assignee: TIW CorporationInventor: Britt O.

Patent number: 10214984Abstract: A system including a gripping tool and a rotary cutting tool may be used to grip a section of casing while cutting through a lower portion of the casing in a single trip. The gripping tool includes a mandrel with a flow bore extending therethrough, a slip actuator received on the mandrel, at least one slip corresponding to the slip actuator, a housing disposed around at least a proximal end of the mandrel, and a collet assembly disposed proximate the at least one slip. The rotary cutting tool is coupled to the mandrel. The gripping tool also includes a bearing assembly that enables the mandrel and the rotary cutting tool to rotate while the at least one slip is remains stationary engaging an interior wall of a casing. The system may include a hydraulic power section to help with setting the slips and removing the cut casing from the wellbore.Type: GrantFiled: March 15, 2018Date of Patent: February 26, 2019Assignee: TIW CorporationInventor: Britt O.

Patent number: 10184307Abstract: A ball seat is expanded and held in place within a casing using an expander. The ball seat includes one or more gripping elements and one or more sealing elements. An apparatus for expandably installing a ball seat in a casing includes a ball seat having one or more gripping elements and one or more elastomeric sealing elements disposed on an exterior of an expandable sleeve portion of the ball seat that is expanded by pulling an expander into the bore of the expandable sleeve portion of the ball seat. A mechanical fuse is predisposed to fail at a level of force sufficient to move the expander to the installed position. Failure of the fuse and further movement of a pulling mandrel positions a channel on the mandrel into alignment with a distal end of the collet, enabling the collet to collapse and pass through the expander for removal.Type: GrantFiled: June 16, 2015Date of Patent: January 22, 2019Assignee: TIW CorporationInventors: Ahmad Warid Abdel Bar, Britt O.

Patent number: 10041322Abstract: A gripping tool having a mandrel reciprocatable within a slide member, the mandrel having a top connector for connecting to a tubular string and a bottom connector for connecting to a cutting tool, the slide member having at least one radially outwardly biased friction member and a slip cage with at least one window through which a slip is deployable, by movement of the mandrel within the slide member, to engage and grip a section of casing to be removed from a well, the mandrel being rotatable by rotation of the tubular string to operate the cutting tool with the gripping tool in the gripping mode. After detachment of the section of casing by the cutting tool, the gripping tool and the gripped section of casing are pulled from the well. The gripping mode is restorable to a running position to reset the tool in the casing.Type: GrantFiled: November 2, 2015Date of Patent: August 7, 2018Assignee: TIW CorporationInventor: Britt O.

Patent number: 9896914Abstract: An expansion tool includes a housing and a hydraulic power section for stroking an expander on a pulling mandrel through a bore of an expandable liner, the expansion tool including a ratcheting reaction assembly, having a ratchet rack and a ratcheting component thereon, that engages a proximal end of the liner to prevent axial movement of the liner as the expander is drawn through a portion of the bore of the liner to expand the liner. The ratcheting reaction assembly remains engaged with the proximal end of the liner as the housing is repositioned uphole to permit staged expansion of the liner using the expander. The expansion tool improves sealing and structure integrity of the expanded liner within the casing by maintaining the liner in a position throughout the staged expansion process.Type: GrantFiled: January 7, 2016Date of Patent: February 20, 2018Assignee: TIW CorporationInventor: Britt O.
