As an alternative technology to mitigate the carbon dioxide (CO2) concentration from the atmosphere, geological sequestration had been widely accepted as a practical option because of the potential capacity and the relative safety in comparison with another option-ocean sequestration. To investigate the sciences and technologies concerned with it, Research Institute of Innovative Technology for the Earth (RITE) initiated a research and development project for CO2 geological sequestration. The field experiment had been conducted at Nagaoka, Japan. For this technology, one of the geophysical dynamics additionally induced to the original geosystem is the dissolution of injected CO2 into the reservoir water, which is a way for storage. The density of dissolved water is changed leading to a gravity flow. This flow can make contribution to the evolution of CO2 enriched water in the terms of buoyancy.
