Resumo:

The use of 3D modelling in geosciences has become increasingly present in its various applied areas nowadays. This chapter presents a compilation of the international CO2 storage resource assessment methodologies and their correlation with the use of computational 3D geological modelling techniques currently available through commercial software and open-source alternatives. The applications of these techniques are then discussed concerning the existing spatial data available in the Paraná and Santos sedimentary basins, aiming at assessing possible reservoirs for CO2 geological storage. The steps from site selection to initial characterization are addressed, including determining storage capacity according to international standards.
