A property characterising agility of the fluid -phase under pressure gradient with account of reservoir permeability and dynamic fluid viscosity:
\frac{k_\alpha}{\mu_\alpha} = k_{air} \cdot \frac{k_{r \alpha}}{\mu_\alpha} |
where
absolute permeability to air | |
relative phase mobility |
In most practical case of a 3-phase fluid model this will be:
oil mobility | |
gas mobility | |
water mobility |
