Patent number: 11414930Abstract: Provided, in one aspect, is a deflector assembly. The deflector assembly, in one embodiment, includes a deflector body having a deflector window located therein, and a deflector ramp positioned at least partially across the deflector window, the deflector ramp configured to move between first ({circle around (1)}), second ({circle around (2)}) and third ({circle around (3)}) different positions when a downhole tool moves back and forth within the deflector body.Type: GrantFiled: February 4, 2020Date of Patent: August 16, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Brian Williams Cho, Matthew James Kelsey, Loc Phuc Lang, Stefano Cappiello

Patent number: 11268339Abstract: Methods and apparatus for milling a window for a lateral wellbore in a casing string. An example method introduces a milling assembly into a primary wellbore, the milling assembly comprising: a whipstock, a guide bar coupled to the whipstock, and a wash pipe coupled to the guide bar. The method further includes running the milling assembly to a depth at which it is adjacent to the window in the casing string; securing the whipstock in the casing string; decoupling the wash pipe from the guide bar; guiding the wash pipe to mill the guide bar without milling the whipstock; and milling the window in the casing string with the wash pipe.Type: GrantFiled: June 29, 2020Date of Patent: March 8, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Benjamin Luke Butler, Aihua Liang, Loc Phuc Lang

Patent number: 10794152Abstract: A support device may include an upper portion that has a first width and a base portion that has a second width. The support device may be sized to be positioned within a tubing string. The support device may be removable from the tubing string. The support device may include a vertical support that connects the upper portion to the base portion. The vertical support may have a third width and defining a fluid flow path between the vertical support and an inner surface of the tubing string.Type: GrantFiled: May 3, 2017Date of Patent: October 6, 2020Assignee: Halliburton Energy Services Inc.Inventors: Loc Phuc Lang, David Joe Steele, Aihua Liang

Patent number: 10557331Abstract: A well system including a parent wellbore, a lateral wellbore extending from the parent wellbore, and a reentry window assembly installed within the parent wellbore and including a completion window assembly having a window and providing an upper coupling, a muleshoe, and upper and lower slots provided on opposing axial ends of the window. An isolation sleeve is positioned within the completion window assembly and includes a sleeve alignment key, a sleeve coupling, and an engagement device. A whipstock is matable with the sleeve coupling and an aligning tool is operatively coupled to the whipstock and engageable with the muleshoe to angularly orient a whipstock face to the window. The isolation sleeve is movable between closed and open positions to isolate the lateral wellbore, and the sleeve alignment key interacts with the upper and lower slots to angularly orient the isolation sleeve while moving between the first and second positions.Type: GrantFiled: June 2, 2016Date of Patent: February 11, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Franklin Charles Rodriguez, Wesley P. Dietz, Homero D. Maldonado, Loc Phuc Lang

Patent number: 10364607Abstract: A whipstock assembly includes a whipstock providing a ramped surface, and a mill releasably coupled to the whipstock with a shear bolt and providing a mill profile. A tension arm is pivotably coupled to the whipstock and movable between a stowed position, where the tension arm is received within a cavity defined in the ramped surface, and an engaged position, where an engagement head of the tension arm mates with the mill profile to assume at least a portion of a tensile load assumed by the shear bolt.Type: GrantFiled: September 27, 2016Date of Patent: July 30, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Matthew Bradley Stokes, Loc Phuc Lang

Patent number: 9932793Abstract: An example whipstock assembly includes a whipstock providing a ramped surface and a longitudinal groove defined in the ramped surface. A lead mill is coupled to the whipstock with a shear bolt and providing one or more blades, and a bearing support is arranged within the longitudinal groove and provides opposing sidewalls that define a slot configured to receive one of the one or more blades and thereby prevent the lead mill from rotating with respect to the whipstock.Type: GrantFiled: July 28, 2014Date of Patent: April 3, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Loc Phuc Lang, William Wallace Dancer
