For torque-and-drag calculations, we use the soft-string model based on the SPE 11380 standard, combined with the Kyllingstad-He buckling model described in SPE 25370, which accounts for wellbore dog-leg severity. This combination ensures fast and accurate modeling of loads on the drillstring and casing during various operational scenarios.

Our T&D calculation module has been thoroughly validated, demonstrating high accuracy in both laboratory testing and real-world drilling data analysis.
