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