The distributed CO2 storage, which is neutralizing CO2 and sediment in the shallow aquifer, is small-scale storage and is located around emission areas. Carbon dioxide (CO2) included micro-nano bubbles is one approach in neutralizing CO2 and sediments by increasing CO2 volume per unit volume of water and accelerating the chemical reaction.However, the thorough investigation on the behavior of micro-nano bubble water in sediments has yet not been ventured. In order to design underground treatment for CO2 gas in the subsurface, it is required to elucidate the behavior of CO2 included micro-nano bubbles such as trapping, advection and so on. In this study, the in-situ test was carried out by injecting CO2 included micro-nano bubble water into the injection wellwhile simultaneously sampling and analyzing the underground water quality from the viewpoint of the neutralizing CO2 and sediments. Additionally, the electrical resistivity tomography test was tried to monitor the moving micro-nano bubble water between wells.
