ICP=33 Parker 3-phase function, alternative 2

ICP = 33 as ICP = 31, except that the capillary pressures are modified for small gas saturations to reduce the derivative.

If $S_l$ + $S_n$ > 0.99,

${P_{cgn}}\quad = \quad {P_{cgn}}\frac{{1 - {S_l} - {S_n}}}{{0.01}}$

If $S_l$ > 0.99,

${P_{cnl}}\quad = \quad {P_{cnl}}\frac{{1 - {S_l}}}{{0.01}}$
