Permeability Anisotropy �� Assume Assume that that permeability permeability in in the the direction direction of of fractures fractures is is maximum maximum permeability permeability and and the the one one perpendicular perpendicular to to that that is is the the minimum minimum permeability. permeability. Minimum Minimum value value is is the the base base value. value. �� The The enhanced enhanced permeability permeability is is calculated calculated as: as: �� Based Based on on tensor tensor relationship relationship
Dynamic Ranking �� Use the information from all the realizations �� Use different methods to rank realizations – Permeability connectivity – Streamline simulation – Finite difference – simplified simulation – Use observed parameter of interest �� Select three to five realizations for history matching
