An automated drilling system requires a real-time evaluation of the drilling bit during drilling to optimize operation and determine when to stop drilling and switch bits. Furthermore, in the dynamic modeling of drill strings, it is necessary to take

When it comes to optimizing drilling, the focus is on running the bit into the well and performing the drilling efficiently. Included in this are methods for optimizing rate of penetration (ROP), determining the right time to change drilling bits, an

In drilling the reservoir sections of a well, one of the most challenging issues is reducing damage to the reservoir by controlling downhole pressure. Many drilling techniques such as underbalanced drilling (UBD) and managed pressure drilling (MPD) a

A thermo-poroelastic model which is fully coupled to conductive and convective transport processes is employed to analyze wellbore stability and borehole breakout. Using the two-dimensional finite element method, stress distribution around an open bo
