Opis:
The article presents an overview of developing unconventional geothermal systems, such as Hot Dry Rock Systems (HDR), where is used the heat of dry rock and enhanced system with smali water tributary called Enhanced Geothermal Systems (EGS). These systems provide utilization of geothermal energy in reservoirs (i.a. granites) where conventional methods are not possible to use. Operation HDR/EGS involves the use rock heating through warming medium, which flowing between the production and injection boreholes. In most cases medium introduced artifically by hydraulic fracturing. Currently, most of the projects HDR/EGS is in the implementation phase. Based on gathered materials an analysis of the construction and exploitation geothermal systems. Take into account geological and drilling aspects.

Opis:
Petrophysical investigations are fundamental to natural resource exploration. In order to recognise the geothermal potential of sedimentary rocks in central Poland, 259 samples were collected from prospective deep-lying geothermal reservoirs. Parameters measured include bulk density, skeletal density, effective porosity, permeability, average pore diameter and specific surface. Results indicate that at great depths (mostly > 3,000 m below surface) sedimentary rocks show low values of porosity (mainly less than 5%) and permeability (only sporadically in excess of 1 md). These values call for a petrothermal use of reservoirs, for which an Enhanced Geothermal System (EGS) was developed. Reservoirs suited for the EGS are Carboniferous and Lower Triassic sandstones in the central part of Poland (Mogilno-Łódź Trough region and a small part of the Kujawy Swell and Fore-Sudetic regions). In addition, Carboniferous limestones in this area are potentially prospective.

Opis:
The fast-growing discipline in the field of geothermal research is the prospecting for geological structures useful for HDR (Hot Dry Rock) or EGS (Enhanced Geothermal Systems) technologies. In Poland, an interesting area for such research is the Sudetes, particularly the Karkonosze Mts. pluton and Fore-Sudetic Block. The article presents issues of scientific projects prepared in the Division of Renewable Energy of Mineral and Energy Economy Research, Institute of the Polish Academy of Sciences in Kraków, related to the recognition of geothermal conditions of the Sudetic region. On the background of global research, these projects demonstrate an innovative character mainly by targeting research on the analysis of tectonics and volcanism of the Sudetes as important factors of the presence of local positive thermal anomalies. Implementation of the afore-mentioned projects would create the possibility of extending still modest knowledge of the deep geological structure of the Sudetic area.

Opis:
In the years 2010–2013, analysis of rocks that build the sedimentary covers in Poland was carried out from the point of view of utilization of energy accumulated in closed geothermal systems – so-called Enhanced Geothermal Systems (EGS). Preliminary assessment of available digital cartographic data in terms of variability in the structural setting, thickness, and geothermal and reservoir parameters allowed selecting, for detailed studies, an area situated in central Poland in the Kujawy segment of the Mid-Polish Anticlinorium, in the Mogilno-£ódŸ Trough and in the northern margin of the Fore-Sudetic Monocline. A complex structural- parametric model was constructed for this area, which comprised the interval from the base of the Carboniferous up to the base of the Cenozoic. The model was a basis for further modelling (e.g. others, modelling of the electric and thermal energy production potential). The study results indicate that the most favourable conditions for the development of EGS occur in the Lower and Middle Buntsandstein deposits to the NE of the K³odawa salt diapir (in the Krooeniewice–Kutno vicinity). They are buried to depths greater than 5000 m b.s.l., their thicknesses exceed 1000 m and they are characterised by porosity about 2.5%, permeability about 0.1 mD and mean density approximately 2.7 g/cm3.
