| Abstract | The main areas of geothermal interest in Italy are, apart from Tuscany, almost all situated in Western Latium and in the Neapolitan area. The geothermal areas of Latium coincide with the volcanic centres of the Mt. Vulsini, Mt. Vico-Cimini and Mt. Sabatini. The presence of vast geothermal anomalies has been confirmed by numerous deep wells. The reservoir is generally at a depth of 2500 m in carbonate formations (Mesozoic Age) with a generally medium-low permeability. The positive wells produce a mixture of water and steam with temperatures of 140-220 and with high concentrations of gas, mainly C02 and In the Latera area the installation of a 44 plant is in progress, while projects are underway for exploitation in other areas. These are mostly multiple projects of binary group production of electrical energy (Marta) combined with plants for domestic heat production (Torre Alfina) and chemical substance production (Torre Alfina, Cesano). In Campania, geothermal exploration has been carried out in the volcanic areas of the Phegrean Fields and Vesuvius. The Phegrean Fields reservoir consists of thick thermometamorphic volcanic formations with temperatures of 230-350?C at 500-3000 m; geothermal exploitation is problematic due to the low permeability of the reservoir and the high and C02 content of the fluids. The only well drilled in the Vesuvius area showed the presence of a carbonate reservoir with low temperature. |
