Oil wells and gas in Italy are small, highly fragmented and often located at great depths, or offshore, and this made it difficult to both their location and their exploitation.
The oil fields are most important in Italy in Sicily and in its immediate offshore, in particular the field of Ragusa (1500 meters) or that of Gela (discovered in 1956, has similar characteristics to that of Dubrovnik and is 3500 meters deep) and that of Gagliano Castelferrato (discovered in 1960, produces gas and is located about 2000 meters deep).
Besides these there are other fields in the east and Western Europe. There are also one of the most important ones from the Val d'Agri, Basilicata, and the Port of Ravenna in the Adriatic Orsini.
