Abstract

We construct digital rock models and apply lattice Boltzmann (LB) simulation in order to obtain supercritical CO 2 distribution in pore space. Then, elastic properties are evaluated by using homogenization algorithm with finite element method (FEM) from the supercritical CO 2 distribution in pore space in order to construct the relationship between CO 2 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 CO 2 injection pressure, and evaluated P-wave velocity by CO 2 distribution pattern such as patchy or uniform.
