Abstract

Summary

The increasing interest in unconventional resources guides the need to characterize the pore networks of source rocks. Unlike conventional reservoir rocks, basin mudrocks rich in organic matter are more complicated to characterize due to its very fine allochemicals grain size (silty to clayish grain sized), causing a very small pore size and very low permeabilities. Petrographic descriptions, scanning electron microscope images, X-ray diffraction analysis, TOC determination and mercury injection porosimetry were performed on core samples and the results were compared as a function of depth. The results show that there is a direct relationship between mineralogical composition, TOC, porosity values and pore size.
