Abstract
This study reports the findings of a regional investigation of fault seal prediction and production behaviour including several fields in the Halten Terrace area, on the Norwegian Continental Shelf. The Upper Jurassic quartz rich, shallow marine deposits of the Garn Fm are investigated. Faults where Garn Fm. is self-juxtaposed are considered and in short; the study compares production data (fault properties from dynamic flow history matching), 4D and initial pressure data) with fault permeability predictions from a combination of SGR calculations and petrophysical measurement of cored faults. One field also give a calibration point for smearing potential of the shale below the Garn Fm as the faults in this field only provide very limited communication across the shale even if Garn Fm is juxtaposed against deeper stratigraphy.
