What is Permeability Ratio Kc/Kf

[anihita]

I would like to know about the Permeability Ratio (Kc/Kf) , which is used in Perform application.

How is this calculated and what is the average range for this permeability ratio.


Thanks

Its been many years, but from memory it is the ratio of crushed permeability to formation permeability, and it relates to the damage around perforation tunnels. Cant remember suitable ranges, but suggest that you do some simple darcy calcs with a range of reasonable skins and see what Kc/Kf you need to put in there to replicate similar inflow characteristics.

Finally, I found the text material on crushed zone permeability and well completion.
