Abstract

Methods and systems include using downhole data to determine a static bulk modulus of dry rock or rock frame in a porous formation and determine a static bulk modulus of grain minerals in the porous formation. Biot's coefficient for the porous formation can be determined based on the static bulk modulus of dry rock or rock frame and the static bulk modulus of grain minerals. Effective stress of the porous formation can be determined based on Biot's coefficient. Effective stress of the porous formation is used in geomechanical applications, including hydraulic fracturing, wellbore stability analysis, and reservoir integrity assessments.
