Figure 11. The final result is a property model that can be used directly in a flow simulation. One great advantage of constructing a model using this method is that the outcrops can be seen juxtaposed with the data. This illustrates very well the problems involved with upscaling and the typical loss of geologic detail. Here, the lower channel surface can be seen on the photorealistic outcrop model to the right with a slice through the 3D porosity model.
