[[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.

==Critical elements of pore-system geometry==
The pores of a rock occur between grains or crystals, in fractures, or in vugs. A rock's storage capacity is controlled by the size and number of pores. A rock's [[permeability]] (flow capacity) is controlled by the size, shape, and number of the pore throats (connections) per pore. Four critical elements of the geometry of a rock's pore system are
* Pore system shapes
* Pore and pore throat sizes
* Pore connectivity
* Ratio of pore throats to pores
==See also==
* [[Classifying pore systems]]
* [[Pore system shapes]]
* [[Pore and pore throat sizes]]
* [[Connectivity and pore throat size]]
* [[Classifying pore systems]]
* [[Determining pore throat size from Pc curves]]
