darcy

n:a unit of measure of permeability. A porous medium has a permeability of 1 darcy when differential pressure of 1 atmosphere across a sample 1 centimetre long and 1 square centimeter in cross section will force a liquid of 1 centipoise of viscosity through the sample at the rate of 1 cubic centimetre per second. The permeability of reservoir rocks is usually so low that it is measured in millidarcys....

Darcy

Measurement of rock permeability, i.e. the extent to which it will allow a fluid to flow through it. The permeability of most oil and gas reservoir rocks is measured in millidarcies, (thousandths of a Darcy)

darcy

(from the article `permeability`) The standard unit of permeability is the darcy, equivalent to the passage of one cubic centimetre of fluid (having a viscosity of one centipoise) per ... ...and size distribution of constituent rock grains, and degree of cementation of the rock. Permeabilities of rocks vary greatly. Unconsolidated ... ...

Darcy

[unit] A darcy (or darcy unit) and millidarcy (mD) are units of permeability, named after Henry Darcy. They are not SI units, but they are widely used in petroleum engineering and geology. Like other measures of permeability, a darcy has the same units as area. ==Definition== where: The darcy is referenced to a mixture of unit systems. A me...
