Hallo everione.....

I am working on MBAL and I need to calculate Relative permeabilities for each tank/wells for three different models of an abandoned field.Now the problem lies that if I use Corey correlation parameters to input values. then I would be needing J-Functions for which further the contact angle and Surface tension values are unknown and capillary pressure is know only for one tank of one model.It is very important that I need to have a perfect Fw curve match once I come to predictions.
and using assumptions I will increase the Uncertainity of my input data. Can anyone please help me and suggest another alternate for calculating Rel.Perms.and It would be a grace if I am answered in a bit detail....

THanks and waiting for reply....
