The concept of relative permeability implies that different phases sweep through the same rock and under the same pressure gradient at different pace even if their viscosities are the same.

It is closely related to Wettability.

Mathematical models of are summarized in the following table:

The relative permeability depends on the current rock saturation:

k_{r\alpha} = k_{r\alpha}(s = \{s_\alpha\})

For 3-phase Oil + Gas + Water fluid model this is going to be:

k_{rw} = k_{rw}(s_w, s_g)

k_{ro} = k_{ro}(s_w, s_g)

k_{rg} = k_{rg}(s_w, s_g)

Mathematical models of relative permeability are often abbreviated RPM.
