Abstract
In the area Pantano di Civitavecchia, approximately 80 km NW of Rome several hot springs are encountered. 3 deep boreholes had been drilled before 1983, which proved the geothermal potential of the area. For this reason the Directory General for Energy (DG XVII) of the European Commission supported the drilling of the deep well Pantano in the framework of the THERMIE programme. The well was drilled in 1983 reaching a depth of 665 m. The geothermal reservoir layed beneath the clay and flysch cover, within the karstic limestones. Production tests indicated that the well yields 68 of water with temperature of 48?C and salinity of 3 At present 20 ha of geothermal heated greenhouses are in operation in the area utilizing water of from 6 productions and 2 reinjection wells with corresponding energy savings at 2,000 toe annually.
