Matching MICP data

[malmajid]

I have a sandstone sample that I obtained MICP data and I am trying to match the data with a pore network model so that I can predict relative permeability on that constructed model. The problem is that the MICP algorithm always gives me a sharp increase in saturation, unlike the experimental data. Do you guys have any advice as to how to play around with the distribution to try to have a better match?
