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 Nanodarcy
The nanodarcy (nD) equals 10⁻⁹ D ≈ 9.869 × 10⁻²² m², the standard permeability unit for ultra-tight unconventional reservoirs. Barnett, Marcellus, and Eagle Ford shale matrix: 1-1 000 nD; crystalline basement rocks and caprocks: below 1 nD. Measured by pulse-decay or GRI crushed-rock methods. 1 nD = 10⁻³ µD = 10⁻⁶ mD.
