(electromagnetism)
The ratio of the permeability of a substance to the permeability of a vacuum at the same magnetic field strength.
(geology)
Specific permeability of a porous rock formation to a particular phase (oil, water, gas) at a particular saturation and a particular saturation distribution; for example, ratio of effective permeability to a specified phase to the rock's absolute permeability.

The sand fluidity [I.sub.2] actually reflected the change of the sand phase permeability during the sand migration process.
In track 9, the Sspw is the saturation corresponding to the wetting and nonwetting phase permeability equal points, and SW RESULTS is the standardized wetting phase water saturation.
In this study, results suggest, however, that phase permeability can be reduced as layer thickness becomes smaller due to increased crystallinity.
