About Darcy
The darcy (D) ≈ 9.869 × 10⁻¹³ m², the oilfield-standard permeability unit defined by Darcy's law: 1 D passes 1 cm³/s of 1 cP fluid through 1 cm² cross-section under a 1 atm/cm gradient. Highly permeable consolidated sandstone: 1-5 D; unconsolidated sand: 5-20 D. 1 D = 1 000 mD ≈ 0.9869 µm².
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.
