Geothermal resources utilisation in the Republic of Croatia in the year 2000

According to previous investigations, Croatia is endowed with significant geothermal potential in the Pannonian area. The temperature gradient in this region ranges from 0, 03 to 0, 07 0C/m. The terrestrial heat-flow density is also high, ranging from 60 to 100 mWm3, and occasionally up to 120 mWm3. In Croatia, are at least 30 springs of the thermal water exist with temperature from ranging 17 to 65 0C. In the Pannonian region more than 50 deep boreholes have been drilled through the geothermal aquifers where temperature range from 40 to 170 0C. For some of these, the geothermal fields have been defined, but the majority still requires further investigations. Most of the geothermal areas have many boreholes drilled into the aquifers, but their thermal waters are still not in use. A small portion of known geothermal energy potential in Croatia is currently under exploitation, but because geothermal reconnaissance has not been completed new installations can be expected in the future.
