Content<\/strong><\/p>\n The aim of the INRIGeoTeam project is to achieve a scientific breakthrough in understanding the processes of reinjecting thermally used groundwater to heterogeneous and anisotropic intergranular aquifers of the Pannonian Basin and to assess the regional hydraulic and thermal impact of this process. The fundamental scientific starting point of the INRIGeoTeam research is that the expected decrease in injectability during reinjection into the Upper Pannonian intergranular geothermal aquifer in the Pannonian Basin is the result of a combination of several processes. These are related to in-situ geological factors at the regional, local and\/or micro level, the ignorance and disregard of which in the dimensioning phase of the reinjection well and the surface use system and also during the dynamics of the doublet operation can cause undesirable physical, chemical or biological processes between the bedrock and the cooled and partly chemically altered thermal water, which lead to a noticeable decrease in injectability and “inefficiency” of the reinjection well. Our basic hypothesis is that reinjection into Upper Pannonian stratified, heterogeneous and anisotropic poorly lithified sandstone with dominant intergranular porosity is effective if the petrophysical and physico-chemical characteristics of this geological medium are taken into account and the prevailing risks for physical, chemical or biological processes that may reduce injectability are previously identified.<\/p>\n The 3rd International Geothermal Summer School took place in Ljubljana (June 30\u2013July 5, 2025) \u2013 Collection of abstracts from the student conference<\/a>.<\/p>\n Project phases and realization\u00a0<\/strong><\/p>\n<\/li>\n<\/ul>\n There are four activities (DP) planned with several results (R):<\/p>\n DP1\u00a0<\/strong>\u00a0Data digitization and creation of digital twins<\/strong><\/p>\n R1.1.1\u00a0Data organization proposal and tool selection \u2013 Achieved\u00a0<\/p>\n R1.2.1\u00a0GeoZS digital geothermal database \u2013 In progress<\/p>\n R1.3.1 3D geological model of pilot area \u2013 In progress<\/p>\n R1.4.1 3D numerical hydraulic and geothermal model of pilot area \u2013 In progress<\/p>\n DP2\u00a0<\/strong>\u00a0Determination of limiting factors in thermal water reinjection\u00a0<\/strong><\/p>\n R2.1.1 Determination of mineralogical\u2026 and geothermal properties of cores \u2013 Achieved<\/p>\n R2.2.1\u00a0Interpretation of hydraulic and thermal processes during reinjection at laboratory level \u2013 In progress<\/p>\n R2.3.1\u00a0Introduction to modern laboratory methods in Europe \u2013 In progress<\/p>\n R2.3.2\u00a0Development plan for a geothermal laboratory at GeoZS \u2013 In progress<\/p>\n DP3\u00a0<\/strong>\u00a0Establishment of a research scheme for successful\u00a0 operation of reinjection<\/strong><\/p>\n R3.1.1 Identification of key factors for successful reinjection\u00a0\u2013 Achieved<\/p>\n R3.1.2\u00a0 Proposal of a methodology for determining the impact radius of a doublet \u2013 In progress<\/p>\n R3.2.1\u00a0 Introduction of developed approach into existing guidelines\u00a0\u2013 In progress<\/p>\n DP4\u00a0<\/strong>\u00a0Dissemination of project results<\/strong><\/p>\n R4.1.1\u00a0 Four original scientific articles\u00a0\u2013 In progress<\/p>\n R4.1.2:\u00a0 Four conference papers\u00a0\u2013 Achieved<\/p>\n R4.2.1\u00a0 Inclusion in the geothermal summer school\u00a0\u2013 Achieved<\/p>\n<\/p>\n Bibliography<\/strong><\/p>\n<\/li>\n<\/ul>\n RMAN, Nina, LAPANJE, Andrej, GER\u010cAR, David, RAJVER, Du\u0161an, ATANACKOV, Jure, BORKO, Karlo.
