Corey's exponent for generating relative permeability curves,nw and no

Corey's exponent for generating relative permeability curves,nw and no

(OP)
Hi all,
Finally I got this forum to ask this and hope someone helps:).
I'm matching experimental data and the best match I could get is if I use higher corey exponents.However, I'm not sure how reasonably high I can go. I saw a couple of papers/articles doing simulation with different values of nw and no for water wet and oil wet respectively.I reduced the end points in order to delay production but still the simulated is faster than the experimental data (everything else is great though).However, if I use higher corey's exponent ,for example nw=no=4, it is perfect.The question is whether it is justifiable to use that in the case of strongly water-wet and oil-wet core(carbonate).
Any suggestion please appreciated
Thanks in advance
