[[Pore systems|Pore type]], [[Pore system shapes|pore geometry]], and [[Petroleum reservoir fluid properties|fluid properties]] are critical factors affecting [[permeability]]. Sandstone texture directly affects pore type and geometry. Knowing what textures and fluids to expect, as well as what [[authigenic clay]]s might be present, can help us predict permeability.
