ICP=34 Parker 3-phase function, alternative 3

ICP = 34 as ICP = 31, except that the capillary pressures are smoothened out for small gas saturations.

If $S_l$ + $S_n$ > 0.99,

${P_{cgn}}\quad = \quad {P_{cgn}}[ - {10^6}{({S_l} + {S_n} - 0.99)^3} + 1]$

If $S_l$> 0.99,

${P_{cnl}}\quad = \quad {P_{cnl}}[ - {10^6}{({S_l} - 0.99)^3} + 1]$
