Abstract: In this work we present a methodology suitable to identify a caprock-reservoir system for the CO2 storage in the Sulcis Coal Basin (SW Sardinia – Italy). The petrophysical and geophysical characterizations indicate that the potential carbonate reservoir (“Miliolitico” Fm. Auct.) located at the base of the Eocene stratigraphic sequence in the mining district of the Sulcis Coal Basin, southwestern Sardinia, is heterogeneous but presents suitable reservoir zones for the storage of the CO2. The GPS data analysis indicates that the study area is stable, since it is characterized by a surface crustal deformation smaller than 1 mm/y.
Description: The analysis of all the experimental data acquired during this study has provided an essential contribution to the characterization of the caprock-reservoir system respectively made up of the continental terrigenous Cixerri Fm. and carbonate Miliolitico Fm. in the Sulcis coal basin (SW Sardinia).
