A property characterising agility of the fluid -phase under pressure gradient with account of reservoir permeability and dynamic fluid viscosity:
\left<\frac{k_\alpha}{\mu_\alpha} \right> = k_{air} \left<\frac{k_{r \alpha}}{\mu_\alpha} \right> |
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 |
