1. 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)

2. 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.

5. Darcy
   A `darcy` (or `darcy unit`) and `millidarcies` (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: Permeability measures the...
