Abstract
The present work involves a comprehensive experimental determination of porosity and pore size distribution in rocks from oil fields formations by deuterium (2H) Nuclear Magnetic Resonance (NMR) and Positronium Annihilation Lifetime Spectroscopy (PALS). Both techniques yield complementary results, the PALS measures the average pore size providing bulk information from which the most abundant pore size can be obtained, the NMR allows the determination of the relative pore size distribution accurately. Both techniques give complementary information to obtain an absolute pore size distribution.
