[[Porosity]] consists of relatively large voids, or pores, distributed among smaller passages called pore throats. A pore system is an aggregate of pores and pore throats that shares a similar morphology. These elements play a role in determining reservoir and seal petrophysics (the characteristic way that oil, gas, and water move through rocks). The figure below shows typical 3-D pore system geometries found in intergranular, intercrystalline, vuggy, or fractured rocks.
