Abstract

Two-phase flow is important to discuss the displacement mechanism between brine and super critical CO₂ in the reservoir. The capillary number (C_a) is essential parameter to control the CO₂ flow in porous sandstone. In this study, we try to estimate the effect of C_a on CO₂ behavior by CO₂ injection experiment. The CO₂ is injected porous sandstone with changing flow rate (FR) and measure P-wave velocity (V_p) and electrical impedance (Z), simultaneously. The CO₂ produces very low C_a-flow in porous sandstone. V_p indicates rapidly reduction with increasing C_a under this CO₂-flow condition. On the other hand, Z shows clearly increment with increasing C_a. Both of parameters mean the increasing CO₂ saturation (S_CO2) with increasing C_a.
