Abstract

In this study, we conduct a simultaneous measurement of V_p and V_s of porous sandstone during drainage and imbibition to monitor the change of CO₂ saturation (SCO2) in porous sandstone under in situ pressure and temperature conditions. We estimate the SCO2 from the change in V_s. The relationship between measured V_p and SCO2 indicates two interesting results. First, we can find that V_p does not recover to pre-drainage levels after the end of the imbibition process. This unrecovered V_p is considered to be the effect of residual trapped CO₂. Second, there is a hysteresis between drainage and imbibition. Finally, we investigate the V_p-V_s relation and find clear differences between water-saturation and irreducible water-saturation. From the V_p-V_s relation, we also identify the un-recovered V_p-changes between drainage and imbibition. These results indicate the high-potential of monitoring the change of SCO2 from V_p and V_s.
