Negative Correlation between Porosity and Permeability Problem

[alali]

Dear All
Is it possible to change Negative Correlation between Porosity and Permeability to positive?
I am not sure but may averaging or weighting be helpful in such a case
but I am not sure
please help me (and other who have the same problem) to find best way
Thanks a lot

Suggest that you likely have different facies, and need to look at their poro perm relationships separately.
