  • Fatigue analysis procedure for drill string
    Patent number: 11242741
    Abstract: Management of fatigue life includes partitioning a drilling interval into sections, and calculating a stress value for each section. From the stress value, an equivalent alternative stress amplitude is calculated for each location, and a fatigue life consumption value in each section is computed. The fatigue life consumption value across the sections is aggregated to obtain an aggregated fatigue life consumption value, which is presented.
    Type: Grant

  • Drilling energy calculation based on transient dynamics simulation and its application to drilling optimization
    Patent number: 11073009
    Abstract: A method for drilling a well includes applying energy input to a drill string (31) by at least one of rotating the drill string (31) from surface and operating a drilling motor (41) disposed in the drill string (31) to operate a drill bit (2) at a bottom of the drill string (31); an amount of the applied energy not consumed in drilling formations caused by at least one of motion, deformation, and interaction of the drill string (31) is calculated; an amount of the applied energy used to drill formations below the drill bit (2) is calculated; and at least one drilling operating parameter is adjusted based on energy calculation before or during drilling operation.

  • Methods for analyzing and designing bottom hole assemblies
    Patent number: 10400547
    Abstract: A method for selecting a bottomhole assembly, including performing a first dynamic simulation of a first bottomhole assembly, performing at least a second dynamic simulation of the first bottomhole assembly, in which the at least a second dynamic simulation includes a different constraint than the first dynamic simulation, and outputting results for both the first dynamic simulation and the second dynamic simulation, in which the results include at least one output showing performance as a function of position along the bottomhole assembly.
