About Microdarcy (μD)
One millionth of a darcy, equal to approximately 9.869233 × 10⁻¹⁹ m² (~0.9869233 nm²).
History: Adopted extensively with the commercial advent of unconventional shale oil, shale gas, and tight caprock geological storage appraisal.
Common Uses: Unconventional shale formations (e.g. Marcellus, Barnett shales: 1–100 μD), carbon capture and storage (CCS) caprock seal integrity appraisal.
About Square Meter (Permeability) (m²)
The SI coherent derived unit of intrinsic permeability of a porous medium, having dimensions of area (L²). It quantifies the ease with which a fluid flows through porous rock or soil under a pressure gradient independently of fluid viscosity (k in Darcy’s law: q = -(k/μ) ∇P).
History: Derived directly from dimensional analysis of Darcy’s law (1856) formulated by French engineer Henry Darcy during his Dijon public fountain sand filtration experiments.
Common Uses: Geotechnical groundwater seepage analysis, subsurface porous media reservoir simulation, ceramic membrane filter media design.
❓ Frequently Asked Questions
How many Square Meters (Permeability) are in 1 Microdarcy?
There are exactly 9.869233e-19 Square Meters (Permeability) in 1 Microdarcy (1 μD = 9.869233e-19 m²).
What is the formula to convert Microdarcy to Square Meter (Permeability)?
The formula is: Square Meter (Permeability) = Microdarcy / 1.01325e+18. Since 1 Square Meter (Permeability) = 1.01325e+18 Microdarcies, divide the value in Microdarcies by 1.01325e+18.
How do I convert 1 μD to m² manually?
To convert 1 μD to m²: apply the formula Square Meter (Permeability) = Microdarcy / 1.01325e+18. Substituting gives: 1 / 1.01325e+18 = 9.8692e-19 m².
