Hierarchical geological realism for reliable reservoir prediction

This paper shows the value of geological realism of facies modeling on the reservoir predictions by introducing it as three hierarchical levels. We aim to maintain geological realism through a model update process. Metric space approach allows us to include interpretational uncertainty for more realistic predictions. We apply different classification techniques to achieve geologically realistic differentiation between multiple possible geological scenarios. Finally, we aim to introduce the hierarchical approach into automated history matching to validate the choice of geological concept on a West Coast of Africa turbidite example.
