Estimating Permeability in Carbonates Using the Rock-Fabric

Although grain-dominated packstone fabrics plot at an intermediate location between grainstones and mud-dominated limestones, they show more variability because of the large grain size difference. Grain size of grain-dominated packstone ranges from 400 microns for
