Simplified Models for Reactive Transport and Chemical Reactions During CO2 Storage in Saline Aquifers

This study was designed to test simple reactive transport models for CO2 storage in the aquifers and cap-rocks of Upper Silesian Coal Basin (Poland). The following scenarios were considered: 2D model and 1D radial-symmetric models of CO2 storage as well as a 1D model of the aquifer-cap-rock interface. The proposed models can be quickly developed, may be easily modified due to their simplicity, and allow for a fast change of the basic assumptions. Hence, they might be useful for the initial assessment, preceding a more advanced study of CO2 storage conditions.
