文摘
A rock physics model is developed to study the reservoir response under CO2 flooding. We identified significant residual oil saturation zone, potential for enhanced oil recovery. Injected CO2 changes the P-wave velocity and acoustic impedance dramatically. 4D seismic signal will be visible in seismic data even in case of patchy saturation.
