Porosity–permeability relationship for measured core samples. To improve correlation, the data set was subdivided according to stratigraphic units (a), different lithologies (b), distinct petrographic rock fabrics (c), and secondary characteristics (d). Note logarithmic scale for permeability—colored lines represent power lines for each class
