Abstract

This study presents the results of the characterization of carbonate rocks (“Miliolitico” Formation Auct.) located at the base of the Eocene stratigraphic sequence in South-Western Sardinia (Sulcis Coal Basin) that could be used as a natural reservoir for CO2 storage in a very important mining district. The Sulcis Coal Basin is characterised by a significant presence both of minable coal, and of deep carbon layers. The carbonate reservoir characterization carried out mainly by petrophysical and seismic investigations was targeted to provide experimental data useful both for the subsequent geological and numerical modelling.
