The current trend in reservoir simulation is to generate a large number of models (sometimes many thousands) in order to investigate the effects of uncertainty in model parameters. For speed often only coarse-scale models are created. However these may over-look the effects of finer-scale structure. On the other hand generating fine-scale models presents problems because it is time-consuming and the models have to be upscaled to reduce the number of
