About Picometre squared
The picometre squared (pm²) equals 10⁻²⁴ m², used in molecular simulation and crystallography for the intrinsic permeability of dense crystalline solids. Halite and anhydrite crystal lattices have calculated matrix permeabilities below 1 pm²; theoretical studies of gas diffusion through graphene oxide membranes work at this scale. 1 pm² = 10⁻⁶ nm² = 10⁻²⁴ m².
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.
