The rock fabric elements important to petrophysical properties are particle size, interparticle porosity, 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 size, interparticle porosity, separate vug porosity, and the presence or absence of touching vugs.
