Abstract
The paper shows thermal tests results (thermal conductivity, specific heat) carried out during the research project to recognize the potential of hot dry rocks for heat and electricity production in Poland. Analysis of such parameters of the rock medium has fundamental significance in search of structures for location of enhanced geothermal systems (EGS). Analyses of thermal conductivity as well as specific heat determine the possibility of effective extraction of heat from hot rock formations and its efficient transfer to the land surface. Reservoir rock should be characterized by the lowest possible porosity and permeability, and the highest possible thermal conductivity. In order to recognize reservoir parameters of rocks that form potential reservoirs for EGS, 300 samples of sedimentary rocks were taken from 11 wells located in central Poland. For samples, sizes of which enabled measurement of thermal parameters, tests of thermal conductivity and specific heat were carried out. Independently, measurements of porosity were made. The porosity magnitude determines values of measured thermal parameters. Measurements of thermal conductivity of rocks were made for 24 samples collected from Triassic, Permian and Carboniferous deposits in six wells. Measurements of specific heat on rock samples were made for 20 rock samples. Among sedimentary rocks, principally sandstones and limestones with reservoir parameters favourable for this type of systems are considered to be petrogeothermal reservoirs and are often characterized by favourable thermal parameters for EGS.
