Relative permeability to oil percolation while sweeping by gas and no presence of free reservoir water:
| (1) | k_{rog}(s_w)=\frac{k_o(s_g)}{k_a} |
where
k_g(s) | oil permeability in 2-phase Oil + Gas reservoir |
k_a | absolute permeability |
\{ s_o, \, s_g \} | oil and gas reservoir saturation: s_o +s_g = 1 |
