Geothermal reservoir characteristics of Meso- and Cenozoic sedimentary rocks of Budapest (Hungary)

Abstract

The characterisation of deep geothermal reservoirs of sedimentary basins is supported by outcrop analogue studies since reservoir characteristics are strongly related to the sedimentary facies and thus influence the basic direction of geothermal field development and applied technology. Permeability and thermal conductivity are key parameters in geothermal reservoir characterisation and the data gained from outcrop samples serve to understand the reservoir system. New thermophysical data from the Meso- and Cenozoic sedimentary rocks of Budapest include carbonates and siliciclastics of Triassic, Eocene, Oligocene and Miocene age as well as Pleistocene travertine, exposed on the western side of the river Danube in the Buda Hills. Field and laboratory analyses revealed distinct horizons of different geothermal potential and thus enable to identify and interpret corresponding exploration target horizons in geothermal prone depths in the Budapest region as well as in sub-basins of the Pannonian Basins System exhibiting geothermal anomalies.
