The results show a nonlinear decay pattern in wellbore rock temperature over extended drilling.
Increased bottom hole temperature reduces thermal stresses and displacements in wellbore rock significantly.
The thermo-hydro-mechanical coupling effect is focused around the wellbore, affecting formation stress.
This model offers insights that enhance wellbore stability and drilling safety at high temperatures.
