Gurley porosity vs sheffield porosity
WebJun 2, 2024 · If a rock has a lot of gaps between grains it is said to have good porosity and a lot of water can fit between the grains. A rock with good porosity can hold a lot of groundwater. Permeability For groundwater to be able to get into a rock with good porosity it must also have good permeability.
