Formation permeability to a given fluid
\alpha-phase normalised to the reference value, usually to air permeability
k_{air}:
Units = dimensionless
(1)
k_{r\alpha} = \frac{k_\alpha}{k_{air}}
The concept of relative permeability is closely related to Wettability.
Mathematical models of are summarized in the following table:
