Please, I have five (5) reservoir simulation results from five (5) different compositional gradient models. History matching using either of the model will give that model a comparative advantage. How do I know the model that produced the most realistic simulation result? Thank you.
Ikechi,
What are the parameters that you are trying to match? Do you have observed data for history matching, such as rates and pressure?
Ikechi,
in my opinion, you have to focus on what parameters you try to match (flow rates, pressure, GOR, etc) instead of your parameter constrain.
beside that, you have to consider as well to the realization models (if you made it). Sometimes you have good matches in every parameter but the geological distribution pattern properties such as porosity and permeability, or maybe facies or rock types are not make sense.
First of all, check the pressure drop as the most important factor to be matched with real field values. Then, compare Oil and water production rates. Finally, check the gas flow rate but don't freak if it was not matched since most of the times it is not accurately measured .
