    In order to characterize the influence of petrophysical parameters on permeability of rocks, statistical analysis was performed on core data which includes porosity, permeability, density and the percentage of calcium carbonate content. Characteristics of porosity, permeability and the Flow Zone Indicator (FZI) have been presented. There were discovered differences in FZI between the hydrocarbon-bearing sections and the unproductive beds of the well Nowosielec-3, and between reservoir rocks and vaste rocks of the wells Jata-1 and Kończyce-1. A division of data set due to the FZI has been realized and statistical relations between permeability and porosity in homogeneous flow units have been established. Relations describing a mobility of media in pore space for FZI units appeared to be stronger than for the total data set. In order to estimate the effectiveness of Zawisza’s formula for the calculation of permeability in the profile of a well, a comparison has been made between the permeability, estimated through the usage of Zawisza’s formula in the process of the comprehensive interpretation of logs, and between the permeability from cores.
