Research Abstract
In this study, we developed a laboratory test apparatus to clarify the flow and storage characteristics of supercritical CO2 in low permeable sandstone. And the mechanism of flow and storage in low permeable sandstone has been clarified. Furthermore, we constructed a new flow/storage model that considers the mechanism of supercritical CO2 in rocks, and developed a numerical simulation has been conducted. As a result, it confirms that CO2 penetrates low permeable sandstone while branching. It was found that residual gas trapping is the dominant storage mechanism for CO2 geological sequestration in rocks with low permeability. In addition, it is shown that low permeability sandstone is suitable for Deep Saline Aquifer (DSA) when caprock is not required because it can store a large amount of CO2 over a long period of time through residual gas trapping.
