Several geological, geophysical and geochemical studies were performed in the last decades characterizing the southern Tuscany as an area with high geothermal anomalies. Montalcino area is characterized, in the central part, from positive geothermal anomaly with a geothermal gradient > 75 °C/km and a heat flow between 100-150mW/m2, but it must be investigated by surface exploration, prior to drilling of exploratory wells.
From the data collected in the geothermal exploration in this area it is expected a geothermal field with two main reservoirs similar to the ones found in the Bagnore:
A shallow reservoir in Tuscan Formations at depths between 1200 m and 1500 m with temperatures between 120-150 ºC;
A deeper reservoir around the 3000 m within the metamorphic basement with temperatures around 250ºC.
A complete geophysical survey will be carry out to better define the geothermal anomaly and comprises a MT campaign, seismic profiles complementing the CROP’s profiles and gradient wells that will define the best locations for drilling.
Less than 2 km from Bagnore geothermal field
