Abstract (english)
The interest of scientific and stakeholder communities on the exploration of deep carbonate geothermal resources is rapidly increasing due to their widespread occurrence and the possibility of local scale uses for hydrothermal heat and power generation. Within the framework of the HotLime and GeoTwinn projects, funded by the Horizon2020 program, the pilot area of Zagreb (Croatia) was chosen for detailed geological and thermal reconstructions of the thermal reservoir hosted in up to 400 m thick Miocene and Triassic carbonate rocks at a depth of approximately 1 km. Despite promising temperatures (up to 82 °C) and a significant number of wells drilled during the 1980s (27 wells in a 54 km2 area), geothermal exploration of this area did not continue in the following decades. Notwithstanding the number of wells, some of which are fully equipped for production and reinjection, and the location of the wells in the national capital with numerous potential users, only one doublet system is in operation. Stratigraphic logs of the wells, borehole logging data and 30 seismic sections were collected, and works are proceeding on their digitalization and arrangement into a database including chemical analyses of the waters, porosity and permeability measurements and bottom hole temperatures. These data will allow obtaining a comprehensive picture of the geological, hydro-geochemical and thermal settings of the reservoir. Seismic and borehole data will be used to perform a 3D geological reconstruction of the subsurface and highlighting the principal fault systems. Contemporary approach to the research of the geothermal resource based on existing data will serve to demonstrate the resource potential to the decision-makers and decrease the risks for future development.
