About Nanodarcy
The nanodarcy (nD) equals 10⁻⁹ D ≈ 9.869 × 10⁻²² m², the standard permeability unit for ultra-tight unconventional reservoirs. Barnett, Marcellus, and Eagle Ford shale matrix: 1-1 000 nD; crystalline basement rocks and caprocks: below 1 nD. Measured by pulse-decay or GRI crushed-rock methods. 1 nD = 10⁻³ µD = 10⁻⁶ mD.
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.
