Publication number: 20200003013Abstract: A drill bit includes a bit body including one or more blades extending therefrom and a plurality of cutters secured to the one or more blades. A rolling element assembly is positioned within a cavity defined on the bit body and includes a housing, a rolling element rotatable within the housing about a rotational axis, and one or more bearing elements extendable into a corresponding one or more arcuate grooves defined in the cavity to secure the housing within the cavity. The housing encircles more than 180° but less than 360° of a circumference of the rolling element while leaving a full axial width of the rolling element exposed.Type: ApplicationFiled: July 22, 2016Publication date: January 2, 2020Applicant: Halliburton Energy Services, Inc.Inventors: Xianwu Ling, Gregory Christopher Grosz, Brandon James Hinz

Patent number: 10472897Abstract: A drill bit may include a bit body, a plurality of blades on the bit body, and a plurality of cutting elements on the plurality of blades. The drill bit may also include an adjustable depth of cut controller (DOCC) located on a blade to provide depth of cut control for at least one of the plurality of cutting elements. Further, the drill bit may include a positioning unit coupled to the adjustable DOCC and configured to adjust the position of the DOCC relative to the cutting element based on a control signal from a control unit.Type: GrantFiled: March 25, 2015Date of Patent: November 12, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Bradley David Dunbar, Seth Garrett Anderle, Gregory Christopher Grosz

Patent number: 10450842Abstract: A method of designing a downhole drilling tool may include generating a three dimensional (3D) downhole drilling tool model and simulating engagement of the drilling tool model with a 3D model of a borehole bottom. First and second cutting zones of first and second cutting elements may be determined based on areas of the first and second cutting elements that engage the borehole bottom, where the first and second cutting zones respectively have first and second cutting zone shapes. First and second cutting forces for the first and second cutting elements may be calculated based on the respective first and second cutting zone shapes. A drilling efficiency of the drilling tool model may be modeled based at least on the first cutting force and the second cutting force and a design parameter of the drilling tool model may be modified based on the drilling efficiency of the drilling tool model.Type: GrantFiled: August 26, 2014Date of Patent: October 22, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Gregory Christopher Grosz, Shilin Chen

Publication number: 20190249498Abstract: A rolling element assembly includes a rolling element rotatable about a rotational axis when positioned within a cavity defined on a bit body of a drill bit, and a compliant retainer positioned within a retainer slot defined in the bit body. A biasing device is positioned within a device pocket defined within the bit body to bias the compliant retainer against the outer circumferential surface of the rolling element. The compliant retainer secures the rolling element within the cavity while an arcuate portion of the rolling element protrudes from the cavity and exposes a full axial width of the rolling element.Type: ApplicationFiled: October 5, 2016Publication date: August 15, 2019Applicant: Halliburton Energy Services, Inc.Inventors: Brandon James Hinz, Gregory Christopher Grosz, Seth Garrett Anderle

Publication number: 20190003259Abstract: A hybrid drill bit includes both fixed cutting elements and an adjustable cutting structure thereon. An adjustment mechanism is provided to allow an axial position of cutting elements at a leading end of the adjustable cutting structure to be adjusted with respect to an axial position of the fixed cutting elements. The adjustable cutting structure may include counter rotational cutting members mounted obliquely with respect to a bit body rotational axis, and the adjustment mechanism may dynamically support the adjustable cutting structure such that the axial position of the cutting elements may be adjusted as the drill bit is in operation within a wellbore. The axial position may be adjusted by altering a weight applied to the drill bit within the wellbore.Type: ApplicationFiled: February 26, 2016Publication date: January 3, 2019Inventor: Gregory Christopher Grosz

Patent number: 10066439Abstract: A drill bit that includes a bit body having one or more blades extending therefrom and a plurality of cutters secured to the one or more blades. One or more rolling elements are positioned on the bit body, each rolling element having a cylindrical bearing portion defining a rotational axis. Each rolling element is rotatably coupled to the bit body about the rotational axis within a corresponding pocket defined in the bit body and a locking pin secures the rolling element within the pocket. One or more internal bearing surfaces of the pocket engage the cylindrical bearing portion and the pocket partially encircles the cylindrical bearing portion while leaving a full length of the rolling element exposed.Type: GrantFiled: May 15, 2015Date of Patent: September 4, 2018Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Brandon James Hinz, Gregory Christopher Grosz, Seth Anderle
