Corey's curves (1954)
krl=S^4k_{rl}\quad=\quad{\hat{S}}^4 krl=S^4
krg=(1 − S^)2 (1 − S^2)k_{rg}\quad=\quad\left(1\;-\;\hat{S}\right)^2\;\left(1\;-\;{\hat{S}}^2\right)krg=(1−S^)2(1−S^2)
where S^=(Sl − Slr)(1 − Slr − Sgr)\hat{S}\quad=\quad\frac{\left(S_l\;-\; S_{lr}\right)}{\left(1\;-\; S_{lr}\;-\; S_{gr}\right)}S^=(1−Slr−Sgr)(Sl−Slr)
SlrS_{lr}Slr = RP(1); SgrS_{gr}Sgr = RP(2)
Restrictions: RP(1) + RP(2) < 1
