Abstract

There are some proposals for carbon dioxide (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. We present an experimental study on the formation behavior of CO2 hydrate in sand layer simulated as marine sediments. The formation rate of CO2 hydrate in sand layer was measured by Raman spectrometer and a bulk-scale experiment. The behavior of formation and permeability change in the growth process was observed in the experiment. As a result, the quantity of CO2 sequestration and the spread of CO2 hydrate zone could be estimated on the basis of the data analysis.
