YOu suggest me to take a dynamic model from one Data file and PVT data from another file? DO you mean this??If I do this,,,Is it necessary to change any other properties like Initial pressure,,to avoid extrapoliation in PVT properties??
Yes, that is exactly what I mean.

Now you are correct, you will need to check what initial pressure , FWL, PVT pressure ranges (depth dependent parameters), well positions etc. These will belong to some specific Static Geologic Model that will be with THAT DATA set example.

If this DATA Static Model (geologic model) is not good for you THEN from one of the OTHER DATA examples take the GRID/Properties etc data. You can use ECLIPSE keywords to shift the depth of that model to be more or less the same depth as the one from where you took your PVT data (I assume an E300 example).

There are at least 25 E300 examples to chose from and more from E100, so to ----- together ONE data set should not be a problem.

Then whatever you proposed IS YOUR RESPONSIBILITY. Did you promise too much?
