Abstract
The purpose of the study was to determine the petrophysical characteristics of the Zechstein Main Dolomite (Ca2) carbonates in the S-1 borehole section. The S-1 well is located in the northern part of the Fore-Sudetic Monocline (western Poland), where numerous oil and gas fields have been discovered within the Polish Zechstein Basin. Mercury intrusion capillary pressure, high-resolution X-ray computed microtomography and gas permeability measurements were conducted on 26 samples from the depth interval of 3171 3220 meters. The method used enabled detailed characterization of the pore space geometry and estimation of the most important reservoir parameters effective porosity and permeability. The rock samples reveal the porous, mainly unimodal type of the reservoir space with predominant proportion of mesopores (0.5 2.5 um) in the pore space. It determines relatively high values of effective porosity (up to 27%) and low values of permeability (below few millidarcy). The results derived from applied methods reveal satisfactory degree of correlation. Appropriate identification of these two petrophysical parameters of the formation is a key element for the optimization of the reservoir development.
