A property characterising agility of the oil under pressure gradient with account of reservoir permeability and dynamic fluid viscosity:
| (1) | M_o = \frac{k_o}{\mu_o} = k_{air}\cdot \frac{k_{ro}}{\mu_o} |
where
k_o | |
|---|---|
\mu_o | |
k_{air} | absolute permeability to air |
k_{ro} | relative formation permeability to oil |
\displaystyle M_{ro} = \frac{k_{ro}}{\mu_o} | relative oil mobility |
