Abstract
We proposed a new monitoring framework of CO_2 geological storage, which consists of the NMR technique to monitor the concentration of CO_2 solved into pore water around the bore hole, the streaming potential technique to successively monitor CO_2 migration, and the time-lapse seismic technique. Enhancement in relaxation of NMR signal due to the dissolution of CO_2 into pore water has been demonstrated experimentally. We numerically investigated the monitoring of bore hole current induced by migration of CO_2 due to streaming potential effect.
