Migration and Storage Mechanisms of CO2 with Different Injection Rates

Abstract:

Article Preview

Geological sequestration of CO2 in deep saline formations has been considered as an effective way to mitigate the greenhouse effect. With different rates of injection to a storage formation, the migration and storage mechanisms of CO2 are different. In this paper, we simulated the migration of CO2 based on a generic geological reservoir under simplified conditions. The results show that higher injection rate will lead to higher migration velocity and farther distance from the injection well, while it has no influence on dissolution amount when the total amounts of injected CO2 are equal.
