... The petrophysical properties of intergranular porosity are related to particle size, sorting, and intergranular porosity. Vuggy porosity systems that are interconnected (touching vugs) cannot be directly related to porosity but are related to fracture pore space geometry, large vugs, and collapse...

... and porosity using the Carman-Kozeny equation to create a core scale map of permeability ( Krausea at al., 2009 ). Many coreflood fluids-rock studies performed to assess the changes in permeability when CO 2 saturated brine is in contact with carbonate rocks have been reported in the literature ( Ott et...
