Challenge of modelling the Tilje Fm., Njord Thin intercalations of mudstone and sandstone layers will have a strong influence on the flow properties!
Why use SBED? Core plug data: Tilje 3A Formation Question: Can we derive petrophysical properties from these data (core plugs) that are representative at the grid-cell scale of a reservoir model ? Problems: Kv and Kh are NOT well characterized by core plugs or wireline data. Permeability data measured from core plugs that have a sample volume below the REV will be unrepresentative. Therefore we see extreme variability of plug permeabilities (Kv, Kh) even inside small vertical intervals. Answer: No! But using SBED to model the heterogeneity at a more suitable volume (REV) and using flowbased upscaling to determine properties could be a more realistic solution… Thin intercalations of mudstone and sandstone layers will have a strong influence on the flow properties!
