    The aim of the study was to make geological 3D modelling of the Early Cretaceous deposits in the southern part of the Miechów Trough. This paper contains description of the geological setting of deposits in the southern part of the Miechów Through. Methodology of structural – parametrics modelling in Schlumberger Petrel 2011 software is also described. Based on laboratory data, well logging curves and structural mapping, author created 3D models showing the spatial distribution of shale volume, porosity and permeability in the Early Cretaceous rocks.

    As a result of hydrocarbon exploration in the Palaeozoic formations of the Upper Silesian and Małopolska blocks covered by the Miocene deposits of the Carpathian Foredeep, commercial hydrocarbon accumulations have been discovered in Devonian rocks (Lachowice, Stryszawa, Zalesie, and Niwiska) and in Carboniferous rocks (Nosówka near Rzeszów, Marklowice). In the Miechów Trough, hydrocarbon shows in the Palaeozoic section are scarce, probably due to lacking Miocene seal. The paper presents results of spatial variability modelling of the lithofacies and reservoir parameters in the Devonian and Carboniferous deposits and in their direct cover, i.e. Triassic and Jurassic rocks. The 3D computer model for the area Proszowice - Busko - Pińczów (1200 km$^2$) was constructed on the basis of seismic and laboratory data and results of geophysical well logging. The obtained results indicate that the Devonian and Carboniferous carbonate deposits which predominate in the basement of the southern Miechów Trough represent poor reservoir rocks. However, it is the lack of good-quality regional seal that has essentially interfered with formation of »Palaeozoic« accumulations.
