Abstract

There are some proposals for CO2 storage in underground structures, such as oil/gas reservoirs, aquifers, and sediments. One of the attractive methods of CO2 sequestration is that the exhaust gas containing CO2 is directly isolated in marine geological structure as a solid phase of gas hydrates. An experimental study on the formation behavior of CO2 hydrate in sand layer simulated as marine sediments was carried out. The formation rate of CO2 hydrate in sand layer was measured by Raman spectrometer and a bulk-scale experiment. Fundamental data toward CO2 storage and sequestration in water unsaturated condition could be obtained. The mixed gas of CO2 and N2 was suitable for vast quantity of CO2 storage. The sequestration of CO2 would be possible because of its storage capacity and the permeability change in the sediments. This is an abstract of a paper presented at the 15th International Offshore and Polar Engineering Conference (Seoul, Korea 6/19/2005).
