SUMMARY:

This dissertation presents the preliminary results of a comparative analysis of different petrophysical characterization methods, with emphasis on basic techniques (gas porosimetry and water saturation porosity), computational methods (X-ray micro-computed tomography – μCT, and synchrotron radiation computed tomography – SR-CT), and advanced approaches (nuclear magnetic resonance – NMR). Using a dataset of 108 carbonate rock samples from the Potiguar Basin, located in the state of Rio Grande do Norte, Brazil, the study aims to evaluate the performance, resolution, and accuracy of each technique in determining key properties such as porosity. The results reveal significant discrepancies in porosity quantification depending on the nature of the method employed, while also highlighting the complementarity among the approaches. Statistical and morphometric analyses of the data provided a deeper understanding of the heterogeneity of the pore systems in the samples analyzed, thereby contributing to the optimization of methodological choices in studies focused on carbonate reservoir exploration
