Publication number: 20180274316Abstract: The disclosed embodiments include an assembly for anchoring a tool at a subsurface location in a wellbore. The assembly includes a latch coupling having a latch pocket on an internal surface of the latch coupling. Additionally, the assembly includes an outwardly biased latch having a key latch that in operation interacts with the latch pocket of the latch coupling to secure the outwardly biased latch within the latch coupling. Further, the assembly includes a first sensor disposed in the latch pocket, and a second sensor disposed in the key latch. The second sensor detects the first sensor when the outwardly biased latch is secured within the latch coupling. Furthermore, the assembly includes a communication sub communicatively coupled to the second sensor that transmits an indication to a surface of the well that the outwardly biased latch is secured within the latch coupling.Type: ApplicationFiled: December 27, 2016Publication date: September 27, 2018Inventor: William Wallace DANCER

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

Patent number: 9238949Abstract: Disclosed are systems and methods for providing a casing exit. One method includes introducing into a wellbore a casing section having an outer sleeve and an inner sleeve rotatably received within the outer sleeve, the outer sleeve defining an outer window and the inner sleeve defining an inner window rotationally alignable with the outer window, wherein the inner sleeve defines a first alignment portion engageable to rotate the inner sleeve, advancing the casing section to a wellbore location with the inner window rotationally misaligned with the outer window, extending a deflector tool within the casing section such that a second alignment portion provided on the deflector tool engages the first alignment portion, and rotating the deflector tool such that the inner sleeve rotates with respect to the outer sleeve and moves the casing section into an open configuration where the inner window is rotationally aligned with the outer window.Type: GrantFiled: April 18, 2013Date of Patent: January 19, 2016Assignee: Halliburton Energy Services, Inc.Inventors: William Wallace Dancer, Stacey Blaine Donovan

Patent number: 9062496Abstract: Disclosed are downhole subassembly systems and method of use thereof. One downhole subassembly system is an orientable whipstock subassembly that includes a whipstock apparatus including a deflector surface operable to direct a cutting tool into a casing sidewall to create a casing exit, and an orienting sub comprising an upper coupling operatively coupled to the whipstock apparatus and a lower coupling at least partially engaged with the upper coupling and rotationally movable with respect thereto while in an un-collapsed configuration and rotationally fixed with respect thereto while in a collapsed configuration.Type: GrantFiled: February 6, 2013Date of Patent: June 23, 2015Assignee: Halliburton Energy Services, Inc.Inventor: William Wallace Dancer

Patent number: 8789580Abstract: Systems and methods for providing a casing exit include a casing section having a generally cylindrical outer sleeve including a proximal end and a distal end. The outer sleeve may define an outer window extending between the proximal end and the distal end. A generally cylindrical inner sleeve may be received within the outer sleeve and may define an inner window. The inner sleeve may be moveable between a first position in which the inner window is misaligned with the outer window and the inner sleeve substantially closes the outer window, and a second position in which the inner window is aligned with the outer window. A deflector tool may be configured to engage the inner sleeve and move the inner sleeve from the first position to the second position.Type: GrantFiled: April 30, 2012Date of Patent: July 29, 2014Assignee: Halliburton Energy Services, Inc.Inventors: William Wallace Dancer, Stacey Blaine Donovan

Patent number: 8727022Abstract: Disclosed are systems and methods of supporting a multilateral window or casing joint from pressurized collapse. In one embodiment, a casing joint assembly is disclosed and includes a casing joint having a pre-milled window defined therein, a sleeve arranged at least partially about the casing joint and configured to cover the pre-milled window, and one or more reinforcing members arranged about the casing joint and interposing the casing joint and the sleeve. The one or more reinforcing members are configured to provide radial support to the sleeve.Type: GrantFiled: June 19, 2012Date of Patent: May 20, 2014Assignee: Halliburton Energy Services, Inc.Inventor: William Wallace Dancer
