Sealing effects of multiple shale smears are poorly described by traditional algorithms (e.g. SGR, SSF etc). The newer PSSF algorithm contains a more representative fault rock model, and is directly applicable to some types of fault seal problem at some scales. However, it is an averaging algorithm and explicit object-based models of shale smears are sometimes required. Both the applicability of the different approaches, and the overall effects of shale smears on across-fault connectivity, are strongly scale-dependent.
