Geological and geophysical data from exploration hydrocarbon industry are valuable for reservoir characterisation. In case of abandoned hydrocarbon fields, these data are often made public but limited to vintage data due to confidential policies of oil companies. In Italy, the Adriatic Sea represents a successful hydrocarbon exploration province where a significant amount of geological and geophysical legacy data is public available. Based on collection and processing of these data, mostly acquired during the second half of the XX Century, this work proposes a methodology aimed at 3D modelling and characterisation of the siliciclastic and carbonate reservoir rocks. Modelling of the petrophysical properties was carried out using different approaches, according to the lithology of reservoir. The results show how the adopted workflow allows the understanding of the relationship among stratigraphic, structural and petrophysical properties.
