Capillary pressure curves illustrating the effect of intragranular microporosity on capillary properties. Note the bimodal character of the samples with both intergranular and intragranular microporosity pore types. The plot on the left represents ooid grainstone with intergranular porosity compared with ooid grainstone with both intergranular and intragranular microporosity pore types - from the Cretaceous Rodessa limestone in east Texas. The plot on the right compares dolograinstone with intergranular porosity to dolograinstone with both intergranular porosity and intragranular microporosity pore types - from the Permian San Andres dolomite in west Texas.
