Drill String Design

  • Evaluates torque and drag associated with the planned or actual trajectory.
  • Evaluates the drill string in different operational modes such as drilling, TIH, POOH, etc.;
    • Torque and drag
    • Buckling Severity
    • Side Loading Force
    • Slip Crushing Capacity of each string segment with the actual planned slips
    • Hydraulics
  • Evaluates a drill string design that will meet mechanical loads to prevent drill string failure.
  • Optimizes on critical parameters.
  • Sensitizes on certain variables.
  • Calibrates the torque and drag model based on the actual drilling parameters.
  • Provides pressure drop and ECD for a given drill string to select the optimum drill pipe option.
