Engineering module

Torque and drag

From the survey, string tally, hole program and friction factors, the software computes hook loads and surface torque for every operating mode — pick-up, slack-off, rotating on and off bottom, slide drilling and reaming.

What it computes

Key outputs

  • Per-mode hook loads and torques
  • Broomstick and torque vs depth
  • Effective tension, side force, stress and safety factor along the string
  • Buckling onset with minimum and maximum safe hook loads
  • Load roadmap across the whole section
  • Friction factor calibration from actual rig measurements
Torque and drag results with hook loads by mode and torque plotted against depth
