3D and 4D Seismic AVO Inversion for Updating the Schiehallion Reservoir Model and Prediction of Production Effects

A030 3D and 4D Seismic AVO Inversion for Updating the Schiehallion Reservoir Model and Prediction of Production Effects A.C. Evans* (Shell UK Ltd) H. Dankbaar (Shell UK Ltd) & J. Stammeijer (Shell UK Ltd) SUMMARY Located West of Shetland on the UKCS the Schiehallion Field oil reservoir lies in a Palaeocene deep marine turbidite complex characterized on seismic data by direct hydrocarbon indicators. Amplitude attributes strongly influence the distribution of sand in the full field model built as a reservoir management tool. Recently a test of this existing model involving a comparison of synthetic and real data from a new
