Reef rocks typically have complex porosity, which requires advanced imaging techniques to be analyezed. This study investigates the pore network of a carbonate rock sample from the Zechstein Limestone (Ca1) Wielichowo Reef located on the Wolsztyn Ridge (Western Poland). The paperfocuses on factors constraining permeability. Using X-ray microtomography, two 3D pore diameter models were obtained based on the skeletonized connected pore mask. All skeleton points had diameters computed as twice the values derived from MATLAB ’s bwdist function, while the remaining voxel values were determined using Nearest Neighbor and Scat-tered Interpolant algorithms. It was shown that the rock has an irregular pore structure with a significant proportion of small pores of sizes around 0.2 mm. The bulk nitrogen gas permeability is low due to advanced calcite cementation and high level of fragmentation of bryozoan anceps which could not be continuously dissolved to ensure better pore space connectivity. Wherever larger bioclasts had been dissolved, greater pore diameters approaching 1 mm occurred. These findings highlight the utility of digital image analysis in reef rock research, with particular emphasis on its potential applications in CO₂ storage or hydrocarbon exploitation-related risk assessment.
