| Abstract | Modelling with TOUGH 2 numerical simulator focused on a low temperature sedimentary basin geothermal system identified at Moravske Toplice in northeast Slovenia. Here, the main aquifer is situated in the Pliocene sand but water from the Miocene sandstone is also produced. After the natural state model with continuous heat inflow was established, sensitivity analysis of various input parameters was performed. Rock density, porosity, permeability and thermal conductivity were changed in order to observe their influence on temperature and pressure distribution in the model. Afterwards, the production model with 6 operating wells was set and sensitivity analysis of parameters of the most important aquifer layers was performed. In this case permeability and porosity effects on temperature and pressure distribution were interpreted. |
