Post subject:  Modelling Permeability 
Simple question, but I'm getting two different answers from Petrel users in my office: I've generated a nonlinear POREPERM function to use to distribute permeability. The equation provided is as follows: log(y) = 3.82401 + 44.0022 * pow(x,1)  87.2269 * pow(x,2) where y = permeability x = porosity Can I simply use the equation as shown directly to calculate Ppermeability or do I need to solve the equation for y? i.e. solve log(y) where y is PERM. If the answer is yes, can someone please help me! Thankyou!

Just an update from my post yesterday  I decided to take the data out of Petrel and generate a nonlinear regression function directly for y (PERM) in Excel, which has worked nicely. Sometimes it is better to go back to basics!
