In petroleum geology, pore space and grain geometry are important physical properties of sandstone reservoir rocks, due to their influences on oil and gas reservoir quality. Besides, grain surface roughness has impacts on the permeability, due to the declining flow diameter and on wetting behaviour, adhesion properties of fluids to pore walls in sandstone reservoir rocks. Recent analytical developments applied in geosciences are used to characterize the morphology of mineral grain surfaces, the fine surface structures of diagenetic minerals and to investigate their pore geometry in...
