About Microdarcy
The microdarcy (µD) equals 10⁻⁶ D ≈ 9.869 × 10⁻¹⁹ m², used for tight gas sands, coalbed methane matrix, and low-permeability carbonates. North Sea tight sandstones: 0.01-1 µD; coalbed methane matrix: 1-100 µD; mudrock caprocks: 0.001-1 µD. 1 µD = 10⁻³ mD = 10³ nD.
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.
