	The porosity and permeability of rocks is important in determining ~~what~~ rocks will make good [[oil and gas reservoir\|reservoir]] ~~rocks~~. A rock that is both porous and permeable would make a good reservoir rock as it allows [[oil]] and [[natural gas\|gas]] to move up through the pores in the rock closer to the surface where it can be extracted. The greater the permeability, the easier it is to extract oil from the rock.<ref name="geo"/> Rocks such as sandstone have a very high porosity and permeability and make a productive oil or [[gas well]]. Looking at the permeability of rocks is one way that geologists can determine where a good location for an [[oil well]] is.<ref name="RE1"/>		The porosity and permeability of rocks is important in determining which rocks will make a good [[oil and gas reservoir\|reservoir]].

	Understanding the permeability of different building materials is vital ~~in ensuring~~ that there is no water or vapour intrusion into the [[building envelope]], which could promote rotting of materials or mould growth. In general, permeability is an important consideration for interior wall finishes. In hot and humid climates the permeability of the interior finish of a wall should be much higher than that of the exterior finish of the same wall. This difference in permeability will allow moisture that enters the wall to migrate to the inside of the building where the moisture will be removed by the [[air conditioner\|air conditioning]] system. The reverse is true for cold climates; the exterior finish should have a higher permeability than the interior finish.<ref>CertainTeed. (May 20, 2015).
