| Abstract | The Vienna Basin, located at the trans-boundary region of Austria and Slovakia also including the capital city of Austria, Vienna, is well developed for hydrocarbon production. However, hydrogeothermal utilization has not been applied yet except for several minor scale balneological uses. As the Vienna Basin offers great opportunities for future geothermal use, resource assessment based on 3D numerical modelling and 2D Raster analyses have been performed in the framework of the project Transenergy. Following a multiplet calculation scheme proposed by Gringarten (1978) so called total “Inferred Resources” (Deibert, 2010) in the range of 350GWth have been assessed for 5 hydrogeothermal structures in the Vienna Basin. In contrast at least 230MWth have already been proved at water inflow at hydrocarbon exploration wells located at the identified hydrogeothermal plays (“Measured Resources”). In a next processing step the “Probable Reserves” will be estimated for the Vienna Basin. This term represents the fraction of hydrogeothermal resources, which can presently be recovered in an economical feasible way. The achieved results represent a first bilaterally harmonized step towards a possible future transnational management of near- and trans-boundary hydrogeothermal reservoirs. |
