Stability analysis of bottom-hole drilling bits utilizing an advanced reamer-stabilizer configuration

Background: During deep drilling of oil and gas wells, the dynamic instability of the drill string caused by radial and axial vibrations of the drill bit leads to a reduction in the rate of penetration (ROP), increased tool wear, and deterioration of the wellbore gauge. This problem becomes particularly pronounced when drilling formations with alternating lithology and rock strength. An analysis…
