The rock fabric elements important to petrophysical properties are particle [[Grain sizes|size]], [[interparticle porosity]], [[separate vugs|separate vug]] porosity, and the presence or absence of [[touching vugs]]. These elements can be identified and quantified by microscopic examination of [[Overview of routine core analysis|core]] material and related to petrophysical properties measured on the same material. | The rock fabric elements important to petrophysical properties are particle [[Grain sizes|size]], [[interparticle porosity]], [[separate vugs|separate vug]] porosity, and the presence or absence of [[touching vugs]].
