Publisher New Age International,p. They are not SI unitsbut they are widely used in petroleum engineering and geology. From Wikipedia, the free encyclopedia. Rocks which have small grain size have small permeability, for example, crystalline limestone, clay and metamorphic rocks. Permeability measures the ability of fluids to flow through rock or other porous media. Permeability can also be computed, or approximated, by characterization of the pores within the material as a series of equivalent tubes.

• Darcy (unit) Revolvy

• A darcy (or darcy unit) and millidarcy (md or mD) are units of permeability, named after Henry Converted to SI units, 1 darcy is equivalent to ×10−13 m² or of 20°C.

In this specific setup, 1 darcy is equivalent to m/day. TABLE Conversion Table for Permeability Units Unit Darcy Millidarcy ft/day Darcy 1 × 10–4 × 10–13 Millidarcy 10–3 1 × 10–​7 SP, American Concrete Institute, Farmington Hills, MI,pp.

Darcy's law gives the flow rate in terms of a pressure difference, fluid viscosity, length and area.

## Darcy (unit) Revolvy

The odd combination of units comes from Darcy's original studies of water flow through columns of sand. The darcy is defined using Darcy's lawwhich can be written as:. Soni: Elements of Water Resources Engineering. Water has a viscosity of 1.

Permeability depends on density, viscosity of the fluid and also on the properties of the medium.

An important application is in the study of the flow characteristics of hydrocarbons in gas and petroleum reservoirs.

The darcy is referenced to a mixture of unit systems. In this specific setup, 1 darcy is equivalent to 0.
