Though CO2 leakage from a geological storage site through wells and rifts represents a major concern, it is difficult to monitor the CO2 leakage. In this paper we have experimentally investigated the proton relaxation time (T1) of carbonate-water filled in a porous media at high pressure with an NMR system to see the dependence of T1 on the concentration of CO2. From the results, it has been observed that the higher the CO2 concentration is, the shorter the T1 of the carbonate-water in the porous media becomes. Therefore this information is very useful to apply NMR logging to monitor the CO2 leakage.
