Application of Geophysical Methods for the Recognition of Geothermal Reservoirs Parameters in Poland

Abstract

Geothermal energy in Poland is connected with low - temperature resources accumulated in four geothermal provinces: Polish Lowlands, Carpathians, Carpathians Foredeep and Sudetes Region. Each of these provinces is characterized by different geological conditions and various geothermal water parameters, the determination of which can be supported by geophysical methods widely applied to recognition of the geological structure of the Earth and to petroleum exploration. Seismic and magnetotelluric methods are most frequently used under Polish conditions predominant by low - temperature geothermal resources associated with sedimentary complexes and partly with crystalline rocks. The paper presents the examples of hydrogeothermal investigation supported by geophysical investigation in sedimentary complexes of Polish Lowlands and crystalline rocks of Sudetes area. The results of the research shows that geophysical methods can effectively support the selection of areas optimal for future geothermal investments. Simultaneously, such methods can be important for determination of hydrogeothermal parameters of particular aquifer.
