Assessment of geochemical reactivity of rocks at the Nagaoka CO2-injection test site, Niigata, Japan

摘要：

The new method to compare the reaction potential ofreservoir rocks quantitatively was developed by defining the reaction ratio of rocks based on detailed mineralogy and kinetic data.The sandstone cores sampled from the CO2-injection test site at Nagaoka, Japan, indicated clear variations of this ratio depending on mineral composition of rocks. On the other hand, the actual reaction rate strongly depends on the saturation state in solution. This paper also presents results showing the importance of saturation states on rock reactivity.
