Abstract

Two-phase flow is important to discuss the displacement mechanism between brine and super critical CO2 in the reservoir. The capillary number (Ca) is essential parameter to control the CO2 flow in porous sandstone. In this study, we try to estimate the effect of Ca on CO2 behavior by CO2 injection experiment. The CO2 is injected porous sandstone with changing flow rate (FR) and measure P-wave velocity (Vp) and electrical impedance (Z), simultaneously. The CO2 produces very low Ca-flow in porous sandstone. Vp indicates rapidly reduction with increasing Ca under this CO2-flow condition. On the other hand, Z shows clearly increment with increasing Ca. Both of parameters mean the increasing CO2 saturation (SCO2) with increasing Ca.
