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