📌 Standard Benchmark Reference Values
Standard petroleum engineering benchmark for porous rock reservoir permeability (~0.9869 μm²).
ApproximateAbout Darcy (D)
The standard petroleum engineering and hydrology unit of intrinsic permeability, defined as the permeability of a porous medium that allows a flow of 1 cm³/s of fluid with 1 cP viscosity through a 1 cm² cross-section under a pressure gradient of 1 atm/cm (exact definition: 9.869233 × 10⁻¹³ m²).
History: Named in honor of French hydraulic engineer Henry Darcy (1803–1858) following his pioneering 1856 study "Les Fontaines Publiques de la Ville de Dijon".
Common Uses: Petroleum reservoir rock permeability ratings (prolific sandstone reservoirs exhibit ~1 D permeability), groundwater aquifer characterization.
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 Darcy?
There are exactly 9.869233e-13 Square Meters (Permeability) in 1 Darcy (1 D = 9.869233e-13 m²).
What is the formula to convert Darcy to Square Meter (Permeability)?
The formula is: Square Meter (Permeability) = Darcy / 1.01325e+12. Since 1 Square Meter (Permeability) = 1.01325e+12 Darcies, divide the value in Darcies by 1.01325e+12.
How do I convert 1 D to m² manually?
To convert 1 D to m²: apply the formula Square Meter (Permeability) = Darcy / 1.01325e+12. Substituting gives: 1 / 1.01325e+12 = 9.8692e-13 m².
