About Micrometre squared

The micrometre squared (µm²) equals 10⁻¹² m², the SI-consistent permeability unit used in European reservoir standards and ISO documents. 1 µm² ≈ 1.0133 D - numerically close to but distinct from the darcy. Clean gravel: 1-10 µm²; clean sandstone: 10⁻³-0.1 µm². 1 µm² = 10⁶ nm² = 10⁻⁶ mm².

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.
