ABSTRACT

Podhale (S Poland) is one of the most promising regions in the country in terms of its geothermal resource potential. The use of geothermal waters for heating purposes commenced there in the beginning of the 1990s. The Podhale region provides excellent conditions for the use of geothermal energy, such as a well-developed infrastructure for the heating industry, recreation, balneotherapy and other applications. The assessment of the geothermal potential should always take an accurate identification of the geological conditions into account. This article presents the results of detailed mineralogical, petrographic and petrophysical studies of the best hydrogeothermal structure within the Podhale geothermal system with a single well capacity of up to 550 m3/h. Rock samples collected from the Biały Dunajec PAN-1 borehole can be petrographically classified as crystalline limestones. They consist of two irregularly intersecting zones differing in terms of calcite crystal size. The measured porosity of the structures under consideration, based on microscopic analysis, is below 1%.

Keywords: geothermal resources, rock properties, mineralogy, petrography, Podhale geothermal system.
