Then, elastic properties are evaluated by using homogenization algorithm with finite element method (FEM) from the supercritical CO2 distribution in pore space in order to construct the relationship between CO2 saturation and seismic velocity, in particular, P-wave velocity. It is known that saturation pattern of multiphase fluids (e.g., patchy and uniform saturation) has an effect on P-wave velocity. This study focuses on flow pattern change influenced by different CO2 injection pressure, and evaluated P-wave velocity by CO2 distribution pattern such as patchy or uniform.
