[[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). [[:file:predicting-reservoir-system-quality-and-performance_fig9-9.png|Figure 1]] shows typical 3-D pore system geometries found in intergranular, intercrystalline, vuggy, or fractured rocks.
