Patent number: 10590724Abstract: Milling tools, systems, and assemblies may have an adjustable gauge diameter. An example mill may include a body with tracks thereon. The tracks may slope in an axial direction and may be configured to couple to multiple blades. A locking collar may be positioned on the body and may be movable between multiple locking positions. Each locking position may be axially offset from another. At each locking position, the blades may be located at a different axial position on the body. Where the tracks slope, each different axial positions of the blades may also correspond to a different radial position for the blades. A gauge diameter of the blades may be based on the locking positions of the locking collar.Type: GrantFiled: October 23, 2014Date of Patent: March 17, 2020Assignee: Wellbore Integrity Solutions LLCInventors: Kenneth Daniel Hora, Kenneth M. Nevlud

Patent number: 9951563Abstract: A mill includes a mill body defining a plurality of blades extending in a direction from a center or rotation of the mill body to a gauge surface. The blades define a cutting profile having a minimum diameter at a longitudinal endmost position. The minimum diameter is smaller than a diameter of a drop ball. The cutting profile has an intermediate diameter at most equal to the diameter of the drop ball at a longitudinal distance from the endmost position greater than the diameter of the drop ball. Shear cutters are mounted on at least one of the plurality of blades, mounted such that at least one shear cutter is mounted closer to a center of rotation of the mill body with respect to other cutters mounted to the blades. At least one insert is mounted to the at least one of the plurality of blades rotationally ahead of the shear cutters.Type: GrantFiled: July 30, 2015Date of Patent: April 24, 2018Assignee: Shear Bits, Ltd.Inventors: Timothy P.

Patent number: 9512690Abstract: A cutting element includes a front face and leading face extending between a first and second sides. A leading cutting edge is located at an intersection of the front face and the leading face, and an undulating back-up cutting edge is formed in the front face and extends from the first side to the second side, and defines a leading surface and a trailing surface. A method includes cutting with a tool having a blade coupled to a tool body, and a cutting element coupled to a forward surface of the blade. The cutting element has a leading cutting edge formed at an intersection of front and leading faces, and an undulating back-up cutting edge formed in the front face and defining leading and trailing surfaces. The leading cutting edge of the cutting element contacts and cuts a work piece.Type: GrantFiled: December 16, 2013Date of Patent: December 6, 2016Assignee: Smith International, Inc.Inventors: Charles Grigor, Kenneth M.

Patent number: 8997895Abstract: A system and method to facilitate the drilling of one or more lateral wellbores while eliminating one or more trips downhole. The system utilizes a drilling assembly comprising an impregnated drill bit or other suitable drill bit. The impregnated drill bit is coupled to a whipstock by a connector for deployment downhole in a single trip. The connector comprises a separation device which facilitates disconnection of the impregnated drill bit from the whipstock once the whipstock is anchored at a desired downhole location.Type: GrantFiled: April 14, 2012Date of Patent: April 7, 2015Assignee: Smith International, Inc.Inventors: Shantanu N. Swadi, Philip M. Gregurek, Kenneth M. Nevlud, Charles H. Dewey, Michael G. Azar
