About Metre squared
The square metre (m²) is the SI coherent unit of permeability (dimension [L²]) and the reference for all other permeability units. Most geological materials have k far below 1 m²; clean coarse gravel: ≈10⁻⁸ m²; shale: 10⁻²²-10⁻¹⁵ m². 1 m² = 10¹² µm² ≈ 1.013 × 10¹² D.
About Microdarcy
The microdarcy (µD) equals 10⁻⁶ D ≈ 9.869 × 10⁻¹⁹ m², used for tight gas sands, coalbed methane matrix, and low-permeability carbonates. North Sea tight sandstones: 0.01-1 µD; coalbed methane matrix: 1-100 µD; mudrock caprocks: 0.001-1 µD. 1 µD = 10⁻³ mD = 10³ nD.
