Abstract. The present work involves a comprehensive experimental determination of porosity and pore size distribution in rocks from oil fields formations by Nuclear Magnetic Resonance (NMR) and Differential Thermal Calorimetry (DTC). Both techniques yield complementary results, the DTC measures the amount of heat involved in a phase transition of the sample under study providing bulk information from which the most abundant pore size can be obtained, the NMR allows the determination of the relative pore size distribution very accurately. Both techniques give complementary information to obtain an absolute pore size distribution.
