Patent number: 10539001Abstract: A method for drilling a borehole penetrating the earth includes: inputting drilling parameters as a function of depth used to drill one or more offset boreholes and rate of penetration using the drilling parameters, any drilling dysfunctions that occurred using the drilling parameters, and one or more lithologies as a function of depth for the one or more offset boreholes. The method also includes identifying those drilling parameters that correspond to a rate of penetration (ROP) that meets or exceeds an ROP threshold for each input lithology and a minimum number of drilling dysfunctions or minimum magnitude of a drilling dysfunction to provide identified drilling parameters; correlating a borehole plan comprising a borehole path and one or more assumed lithologies as a function of depth to the one or more lithologies of the one or more offset boreholes; and drilling the borehole with the drill rig using the identified drilling.Type: GrantFiled: November 22, 2017Date of Patent: January 21, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Franck T. Kpetehoto, James Albert Hood, Stephen Carey

Patent number: 9845671Abstract: Methods, systems and products for evaluating a downhole component condition for a drilling assembly in a borehole. Methods include estimating a bending moment on the component at a selected depth along the borehole; estimating a number of rotations of the component at the selected depth; and estimating the condition of the component using the estimated bending moment and the estimated number of rotations at the selected depth. Estimated bending moment may be derived from a borehole model using an estimated deviation on a selected length of the borehole about the selected depth. The condition may be accumulated fatigue or estimated remaining useful life. Estimating the condition may include tracking a total estimated number of rotations wherein the component is subjected to bending moment values in a corresponding moment window, which may be greater than a predetermined threshold bending moment. Weight factors may be associated with at least one moment window.Type: GrantFiled: September 16, 2013Date of Patent: December 19, 2017Assignee: Baker Hughes, a GE company, LLCInventors: Franck T. Kpetehoto, Donald Keith Trichel, Abdallah Ahmed ElKamel, Sandeep S. Janwadkar, Sridharan Chandrasekaran
