Publication number: 20250223871Abstract: Systems and methods for downhole drilling and, more particularly, hydraulic control systems and methods for hydraulically locking and unlocking moveable elements of a drill bit are provided. A drill bit may include a body; a moveable element secured to the body, wherein the moveable element is configured to extend or retract from a surface of the drill bit; a communication channel from the moveable element to a bore in the body; and a hydraulic control system at least partially disposed in the body, wherein the hydraulic control system is configured to at least provide fluid communication from the bore to the communication channel to thereby lock or unlock the moveable element.Type: ApplicationFiled: March 10, 2025Publication date: July 10, 2025Applicant: Halliburton Energy Services, Inc.Inventors: Bradley David Dunbar, Robert Warner, Matt Barnes

Patent number: 12252977Abstract: A drilling system, assembly, and method may help optimize drilling in a system that involves more than one rotary tool that engages the formation. A rotary tool may be a rotary cutting tool, such as a drill bit or reamer, or some other rotary tool (e.g. stabilizer or rotary steerable tool) that has the potential to drag on the wall of the hole being drilled and take energy away from cutting. In an example, a wellbore or portion thereof is formed by rotating a first rotary cutting tool having a first cutting structure in engagement with one portion of the formation together with a second rotary cutting tool having a second cutting structure in engagement with another portion of the formation. Forces are obtained above and below the second cutting structure. One or more drilling parameter or drill bit design parameter are adjusted in relation to a force differential between the forces above and below the second cutting structure.Type: GrantFiled: June 6, 2023Date of Patent: March 18, 2025Assignee: Halliburton Energy Services, Inc.Inventors: Bradley David Dunbar, Matt Barnes, Brody Dunn, Van Jordan Brackin

Publication number: 20170159699Abstract: A flex shaft for a motor may comprise a hollow tubular member with first and second connector ends. In some embodiments, a thickness or wall thickness of the tubular member may be selected in accordance with a desired strength or torque the flex shaft must be capable of handling. In some embodiments, a plurality of openings may be provided in the wall of the tubular member to provide a desired level of flexibility. The plurality of openings may be arranged or patterned in numerous ways discussed herein. The flex shaft allows a shorter overall length to be used than for a conventional solid shaft.Type: ApplicationFiled: December 5, 2016Publication date: June 8, 2017Applicant: Multi-Shot, LLCInventor: Matt Barnes
