The study area in geological sense is located on the Grotów peninsula within Gorzów Block in north-western part of Poland, on the border of Fore-Sudetic monocline and Szczecińska Through. In that area two generalized sedimentary zones were recognized: carbonate platform (barrier and platform plain) and slope of the carbonate platform (edge of the slope with bay plain). The aim of this study is the analysis of the relationships between petrophysical parameters of the carbonate reservoir rocks. This research was conducted on the base of mercury porosimetry for 318 rock samples. The analysis showed that not all pore space is available for the accumulation of hydrocarbons. Availability of pore space for accumulation strongly depends on the average capillary, and the amount of pores with diameter higher than 1 μm. In general, slope of the carbonate platform has better conditions for accumulation of hydrocarbons.
