D020 Reservoir Fault Properties Estimated Using Seismic Shale Gouge Ratio A.D. Irving* (Total E&P UK Ltd) P. Breton (Total SA) & S. Guillon (Total SA) SUMMARY Fault properties estimated using lithoseismic Vclay are compared to those derived from a classical geomodelling approach with reservoir NTG. Throw and Shale Gouge Ratio (SGR) calculation at the seismic scale can provide a significant improvement in resolution and accuracy over the geomodelling approach. Fault properties included in numerical reservoir simulations give a qualitative match to observed production and time-lapse seismic effects in an offshore turbidite field. Errors introduced during upscaling of seismic properties into
