Acoustic approach to determine Biot effective stress coefficient of sandstone using true triaxial cell (TTSC)
Pore pressure change affects the stresses distribution and associated strains within the
reservoir rocks. Applying poroelastic theory, the coupling of pore pressures and stresses can
be represented by the ratio of horizontal stresses over pore pressure changes (ie stress
path). Likewise, the stress path ratio is a function of Biot's coefficient, dynamic and elastic
properties of rocks, and reservoir shape. Stress path ratio can be estimated through
analytical, experimental, and numerical approaches. In this study, the dynamic properties of …
