“…The simulation experimentation results show that the thermal conductivity is the most influencing parameter regarding the production temperature because of its direct relationship with permeability, as confirmed by experimental studies; as the permeability increases, the thermal conductivity rises [36]. The simulation also indicates that porosity has the least effect concerning the reservoir's productivity, compared to the other parameters.…”

a b s t r a c tThis study aims to guide reservoir engineers/managers in the selection of a combination of parameters from amongst various possible alternatives in developing deep geothermal reservoirs which can meet the desired temperature at the production wellhead for sustainable energy production. The work presents an approach for predicting the long-term performance of a deep geothermal reservoir using multiple combinations of various reservoir parameters. The finite element method and factorial experimental design are applied to forecast which of the parameters has the most influence on long-term reservoir productivity. The solver employed is validated using known analytical solution and experimental measurements with good agreement. After the validation, an investigation is then performed based on the Soultz lower geothermal reservoir. The results showed that fluid injection temperature is the parameter that influences the experiment the most during exploitation involving production temperature, whereas injection pressure rate happens to have a more significant impact on reservoir cooling.

“…Numerical modelling was conducted using TOUGH2 code (Bujakowski et al, 2015). The modelled net power of an EGS plant operating in the Kutno area ranged from 1.3 to 1.6 MW depending on the permeability and volume of the fractured zone used for the circulation (Bujakowski et al, 2015). In the Konin area net power of an EGS plant was estimated to range from 1.9 to 2.2 MW, while in in the Pleszów area EGS plant net power was assessed at 2.2-2.5 MW (Wójcicki et al, 2013).…”

Abstract. The current utilization of geothermal energy in Poland consists in development of geothermal waters for needs of heating systems and balneotherapeutic and recreational centres. In Poland, possibility of using the energy accumulated not in waters but in rocks deep-lying below the earth surface represents a new problem. The paper presents results of estimating the petrogeothermal energy resources accumulated in sedimentary rocks of central Poland. This region was distinguished as the most prospective in Poland for the possibility of locating systems that utilize petrogeothermal energy accumulated in sedimentary rocks, with regard to criteria of temperature and depth of occurrence of reservoir rocks.The carried out assessment of petrogeothermal energy resources accumulated in sedimentary rocks has shown a significant potential for using the heat from sedimentary rocks and has enabled indication of the best prospective locations for Enhanced Geothermal Systems. The most abundant resources occur in three locations of central Poland: Kutno area (the Lower Triassic reservoir), Pleszów (the Lower Carboniferous reservoir) and Konin area (the Upper Rotliegend reservoir). In these areas the potential for builiding system based on petrogeothermal energy was identified.

“…Geothermal energy resources in Poland are related to the underground waters of different stratigraphic layers occurring at different depths, within geological units in the Polish Lowland, the Sudetes and the Carpathians. The information about their size is widely known thorough results of numerous research projects [12][13][14][15][16][17][18][19]. The recognition of geological structures for direct or indirect applications of the geothermal energy is an important direction of carried geological research.…”

Abstract. Geothermal energy is considered as a strategic and sustainable source of renewable energy that can be effectively managed in several economic sectors. In Poland, despite the abundant potential of such resources, its share in the energy mix of renewable energy sources remains insubstantial. The utilisation of geothermal resources in Poland is related to the hydrogeothermal resources, however, numerous researches related to petrogeothermal energy resources are being performed. The utilisation of each type of energy, including geothermal, has an impact on the natural environment. In case of the effective development of geothermal energy resources, many environmental benefits are pointed out. The primary one is the extraction of clean, green energy that is characterised by the zeroemission rate of pollutants into the atmosphere, what considering the current environmental pollution in many Polish cities remains the extremely important issue. On the other hand, the utilisation of geothermal energy might influence the natural environment negatively. Beginning from the phase of drilling, which strongly interferes with the local landscape or acoustic climate, to the stage of energy exploitation. It should be noted that the efficient and sustainable use of geothermal energy resources is closely linked with the current law regulations at national and European level.
