Overview
Porosity measures the empty spaces in a material (storage), while permeability measures the ability of a material to transmit fluids (flow). These are key properties in geology and petroleum engineering.
💡
Pro Tips
Porosity is usually expressed as a percentage.
Permeability is measured in Darcys (D) or milliDarcys (mD).
High porosity doesn't always mean high permeability (e.g., clay).

Fun Facts
"The Darcy is named after Henry Darcy, who studied water flow through sand filters in 1856."
"Shale rocks can have very low permeability, requiring hydraulic fracturing to extract gas."
"Most oil reservoirs have porosities between 10% and 30%."
