📌 Standard Benchmark Reference Values
Standard petroleum engineering benchmark for porous rock reservoir permeability (~0.9869 μm²).
ApproximateAbout 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.
About 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.
❓ Frequently Asked Questions
How many Darcies are in 1 Square Meter (Permeability)?
There are exactly 1.01325e+12 Darcies in 1 Square Meter (Permeability) (1 m² = 1.01325e+12 D).
What is the formula to convert Square Meter (Permeability) to Darcy?
The formula is: Darcy = Square Meter (Permeability) × 1.01325e+12. Since 1 Square Meter (Permeability) = 1.01325e+12 Darcies, multiply the value in Square Meters (Permeability) by 1.01325e+12.
How do I convert 1 m² to D manually?
To convert 1 m² to D: apply the formula Darcy = Square Meter (Permeability) × 1.01325e+12. Substituting gives: 1 × 1.01325e+12 = 1.0132e+12 D.
