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 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.
