Abstract
The study concerns mercury injection capillary pressure, X-ray diffraction analysis and gas permeability measurements on the autochthonous Miocene rocks. The core samples were taken from the J-28 and R-6 wells from depth intervals of 1484 3075 and 1685 3406 meters, respectively. The wells are located in the Miocene Carpathian Foredeep Basin in the south-east Poland, nearby the Carpathian frontal overthrust. From the commercial point of view, the Carpathian Foredeep is distinctly prospective for the occurrence of hydrocarbon resources, since more than 120 gas fields in this area were discovered during the last 50 years. Results of the applied laboratory methods enabled the rock classification, detailed analysis of the pore space and estimation of the crucial petrophysical parameters porosity, permeability and brittleness. The analyzed rock samples reveal porous type of reservoir space, characterized by the high proportion of nanopores (<0,1 gm), moderate values of effective porosity (7-8% on average) and extremely low values of permeability (typically lower than 100 RD). The mineralogical composition allows to classify the examined rocks as mixed argillaceous, mixed siliceous or argillaceous/siliceous mudstones. The calculated brittleness indexes allow to infer that examined rock interval exhibit relatively high potential for the hydraulic fracturing performing. The results show that the analyzed Miocene deposits reveal features typical for heterolithic reservoirs with poor capacity and permeability properties, what may suggest the presence of the unconventional gas accumulations.
