The Zechstein Main Dolomite (Ca2) is one of the largest petroleum bearing formations in Poland. Numerous hydrocarbon deposits occur within Ca2 in the carbonate platform sediments of the Polish part of the Southern Permian Basin. Application of modern methods allows evaluation of porosity and pore size distribution and enhances the proper characterization of reservoir rocks in non-invasive way. The study concerns lowfield Nuclear Magnetic Resonance (NMR) measurements conducted on Ca2 carbonate rocks from P-1 well l...

Both complicated dissolution processes and different patterns of fossils? distribution may be expected in carbonate hydrocarbon reservoirs. Therefore, this paper aims to precisely locate such places using few independent analytical tools. Five carbonate samples from the Permian Bro?sko Reef (Western Poland) were studied in a form of both thin sections and cylindrical core samples. The latter were subjected to Computed Microtomography (?CT) and Nuclear Magnetic Resonance (NMR) experiments. While the ?CT helped to p...
