Distribution and Characteristics of Lower Jurassic Reservoirs Onshore and Offshore Sicily (Italy) Sicily

The Lower Jurassic of Sicily is a mature but still interesting portion of a proved petroleum system of the Central Mediterranean Basin. This study on the Inici Fm across the Sicilian onshore and offshore better defines the characteristics of these carbonates. The paleogeographic distribution of the Inici is apparently continuous toward south, while toward the northwest is delimited by the Streppenosa Basin. The extreme variability in the thickness of this unit is both associated to the strong synsedimentary tectonics occurring in the area and often to the mis-recognition of the lower boundary in the wells . In outcrops it is possible to observe the presence of secondary dolomites that are masking the lower stratigraphic contact and are in some way extending the reservoir potential of these relatively tight limestone.
