About Millidarcy
The millidarcy (mD) equals 10⁻³ D ≈ 9.869 × 10⁻¹⁶ m², the everyday unit in petroleum reservoir engineering worldwide. Conventional sandstone reservoirs: 1-1 000 mD; carbonate reservoirs: 0.1-100 mD; economic gas recovery typically requires k ≥ 0.1 mD. Permeameter and well-test reports give results in mD. 1 mD = 10⁻³ D = 10³ µD.
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.
