Simultaneous measurement of Vp and Vs of Tako sandstone


Abstract
We measured Vp and Vs of tako sandstone to confirm the relationship between these two velocities with injecting super critical CO2. From this Vp-Vs relationship, we can monitor the pore fluid change from water to CO2. The results also indicated that Vp/Vs wil be powerful tool to monitor the CO2 behavior in the storage site.
