Seismic Numerical Modelling to Monitor CO2 Storage in the Baltic Sea Offshore Structure

This study is a part of CO2 geological storage research in the Baltic Region. Our research shows the effectiveness of seismic numerical modelling methodology, in particular, synthetic plane-wave and difference sections, to detect the presence of CO2 in deep saline aquifer of Cambrian Deimena Sandstone Reservoir Formation in the E6 Baltic offshore structure for various saturation levels. Our results clearly show the applicability of seismic methods to monitor CO2 plume within the studied Baltic Sea offshore storage site E6. This study plays a crucial role in developing an optimal seismic monitoring plan in the studied area.
