Transenergy - Transboundary Geothermal Energy Resources of Slovenia, Austria, Hungary and Slovakia
Authors G. Goetzl, A. Rotary-Szalkai, G. Toth, A. Nador, G. Maros and L. Maros and G. SchubertApart from enhanced geothermal systems and ground source heat-pumps future geothermal energy supply will still strongly depend on natural hydrogeothermal utilization. In this context the Pannonian Basin covering areas of Hungary, Slovakia, Austria and Slo

Coupled Thermal-hydraulic-chemical Numerical Simulations of CO2 Injection into a Carbonate-hosted Saline Aquife
Authors P. Alt-Epping and L.W. DiamondPredictive numerical models are required to assess the processes during and after the injection of CO2 over spatial- and time-scales that are inaccessible to direct observation. We present results from numerical simulations that examine the effect of perm

Investigation of Large-scale Pressure Monitoring of CO2 Injection on a Real Site Model
Authors K. Benisch and B. Graupner and S. BauerThis paper presents a study on monitoring and assessment of the large-scale pressure behaviour during and after CO2 injection on a real site-scale model in the North German Basin. The study is focused on the conditions, under which significant pressure si

Faults, Facies, and Karst - Intergrated Seismic Interpretation of a Hydro-geothermal Reservoir
Authors H. von Hartmann, H. Buness, R. Thomas and C.M. Krawczyk and R. SchulzTaking into account the heterogeneity of a hydro-geothermal reservoir, sedimentological and diagenetic information must be combined for a sound estimation of hydraulic parameters. Based on a newly processed 3D dataset from the Bavarian Molasse, we evaluat

Matrix Pore Water in Crystalline Rocks
Authors F. Eichinger and H.N. Waber and J.A.T. SmellieMatrix pore water in the connected inter-and intragranular pore space of low-permeable crystalline bedrock interacts with flowing fracture groundwater predominately by diffusion. The amount of pore water in the rock matrix and the volume of gas dissolved

Pre-drill Performance Assessment of Geothermal Aquifers
Authors R.A. Kronimus, H. Mijnlieff, P. van Hooff and A. Obdam and J.D. van WeesExploration for geothermal sites and performance evaluation for the operation of geothermal doublets by reservoir simulators is cost intense. Therefore, a publicly available tool called Doublet Calculator has been developed, allowing the probabilistic mod

Modelling Coulomb Stress Changes due to Fluid Injection and Withdrawal - A Step to Understand Induced Seismicity
Authors A. Troiano, M.G. Di Giuseppe and Z. Petrillo and C. TroiseFluid injection and withdrawal in deep wells is a basic procedure in a series of mining and deep resources exploitation, i.e. oil and gas extraction, geothermal exploitation and EGS permeability enhancement. All these activities have the potential to indu

Geothermal Atlas of Catalonia V.0
Authors I. Marzan, M. Fernandez, C. Puig and X. Berastegui and L. SerraIn 2007 a working group to evaluate the geothermal potential in Catalonia (NE-Spain) was created including five institutions: IDAE, IGME, ICAEN, IGC and ICTJA-CSIC. The primary task was to collect and update all geothermal and related data already existin

Dynamic Permeability due to Physical Coupling of Reactive CO2-flow and Deformation
Authors N.S.C. Simon and Y.Y. Podladchikov and H. JohansenLow permeability reservoirs often show variations of permeability over time, which are conventionally explained by the reactivation or opening of existing fractures or the formation of a new network of (hydro-)fractures due to high fluid pressures.
