Shales are porous but have a lower permeability because the finer grain size creates smaller pore spaces. Igneous rocks …Porosity in sandstones generally takes the form of intergranular pores: the pore space between the grains of quartz and other detrital minerals. In some cases there may be intercrystalline porosity caused most commonly by calcite or quartz cement introduced by diagenesis in the lithification of the sandstone. Porosity inVelocity versus porosity (after Wyllie et al., 1958). The limestone values (plotted as crosses on both Figures 5.4a and 5.4b) are slightly high and the sandstone values (plotted as circles) are reasonable. The line in Figure 5.4b is the time-average equation.In porous sandstone, a lot of our current understanding of both brittle and ductile behaviors is based on acoustic monitoring.
