Abstract
Two-phase flow is important to discuss the displacement mechanism between brine and super critical CO 2 in the reservoir. The capillary number (C a ) is essential parameter to control the CO 2 flow in porous sandstone. In this study, we try to estimate the effect of C a on CO 2 behavior by CO 2 injection experiment. The CO 2 is injected porous sandstone with changing flow rate (FR) and measure P-wave velocity (V p ) and electrical impedance (Z), simultaneously. The CO 2 produces very low C a -flow in porous sandstone. V p indicates rapidly reduction with increasing C a under this CO 2 -flow condition. On the other hand, Z shows clearly increment with increasing C a . Both of parameters mean the increasing CO 2 saturation (S CO2 ) with increasing C a .
