Patent number: 11927091Abstract: A drill bit has a plurality of cutters secured to the bit body, including a gauge cutter defining a gauge diameter of the drill bit. A reciprocating gauge assembly on the bit comprises a cavity defined in the bit body, a piston reciprocably disposed in the cavity, a wear element on an outwardly facing end of the piston, a piston retainer for moveably retaining the piston in the cavity, and a spring biasing the piston outwardly to a neutral position of the wear element with respect to the gauge diameter. The wear element and piston may be urged inwardly in response to an applied load at the drill bit gauge pad, increasing the lateral depth of cut and thereby controlling the aggressiveness of the bit in response to the load.Type: GrantFiled: December 30, 2020Date of Patent: March 12, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Van Jordan Brackin, Trung Huynh, Kelley Leigh Plunkett, Kevin Clark, Andrew David Lake, Darien Louis Gurka, Jr., Daniel Brendan Voglewede, Curtis Clifford Lanning, William Brian Atkins

Patent number: 11859451Abstract: A depth of cut control (DOCC) assembly includes a DOCC element positioned in a retainer pocket along a drill bit blade to limit a depth of cut of one or more fixed cutters. A retention member initially retains the DOCC element within the retainer pocket at a first exposure position. The retention member is configured to release the DOCC element downhole to allow one-way movement of the DOCC element to a second exposure position.Type: GrantFiled: October 15, 2021Date of Patent: January 2, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Kelley Leigh Plunkett, Kevin Clark, Van Jordan Brackin, Chris Propes, Rob Arfele

Patent number: 11280136Abstract: A rolling depth of cut controller (DOCC) includes a first retainer including a body portion having an arcuate inner surface. The body portion extends partially around a central axis between the inner surface and an outer surface from a mating surface to an engagement surface. Further, the body portion extends axially along the central axis. The rolling DOCC also includes a second retainer secured to the first retainer at the mating surface via at least one fastening feature. Additionally, the rolling DOCC includes a rolling element disposed at least partially within a cavity formed between the first retainer and the second retainer. The rolling element is configured to rotate within the cavity about the central axis, and an exposed portion of the rolling element is configured to provide depth-of-cut control for a drill bit.Type: GrantFiled: July 30, 2020Date of Patent: March 22, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Van Jordan Brackin, Kelley Leigh Plunkett, Curtis Clifford Lanning, John William Varner, Nicholas Grant Allison

Patent number: 11060358Abstract: An earth-boring drill bit with brazed-in rolling elements for depth-of-cut control. The earth-boring drill bit includes a bit body, a blade having an exterior surface and defining at least one pocket, and a DOCC element positioned within the blade. The DOCC element includes a walled retainer positioned within the pocket. The walled retainer includes retainer side walls and an endcap attached to the retainer side walls at an end of the walled retainer. The DOCC element further includes a rolling element positioned within and partially enclosed by walled retainer, with a portion thereof extending above the exterior surface of the blade. The disclosure further includes the DOCC element and a method of installing it in the pocket defined by the blade.Type: GrantFiled: June 19, 2019Date of Patent: July 13, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Kelley Leigh Plunkett, Jordan Olear

Patent number: 11053742Abstract: A rotating cutter for a fixed cutter type bit includes an annular sleeve with a retainer having a plurality of inwardly extending tabs and a spindle cutter rotatably coupled to the annular sleeve. The spindle cutter includes a spindle extending into the annular sleeve and rotatable about a central axis of the annular sleeve, a base portion positioned between the retainer and a proximal end of the annular sleeve, and a cutter portion coupled to the spindle. The rotating cutter further includes at least one pin disposed between adjacent tabs of the plurality of tabs of the retainer to prevent axial movement of the base portion through the retainer.Type: GrantFiled: February 21, 2020Date of Patent: July 6, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Trung Quoc Huynh, Van Jordan Brackin, Kelley Leigh Plunkett
