About Kilodarcy
The kilodarcy (kD) equals 10³ D ≈ 9.869 × 10⁻¹⁰ m², used for very high-permeability porous structures. Gravel packs in oil wells: 1-100 kD; vuggy dissolved carbonates: 1-10 kD; loose sand-gravel mixtures: 10-1 000 kD. 1 kD = 10³ D = 10⁶ mD.
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.
