Resumen

This study addresses mud density prediction as part of wellbore stability analyses considering effective rock properties and using friction and elastic theories to determine the deviator stress at failure. The effective rock properties for different sandstone porosities were obtained through the theory of asymptotic homogenization, and the wall vicinity stresses at the borehole wall were estimated considering friction and elastic theories. The use of the method of asymptotic homogenization (MHA) allows obtaining effective rock mechanical properties varying in porosity and saturation conditions.
