Identification and Geological Validation of AVO-driven Opportunities in Infrastructure-led Settings: Examples from NW Europe

Recently processed or reprocessed 3D data in infrastructure-rich settings in the North Sea and on the Atlantic Margin, has been subjected to relative extended elastic impedance (rEEI) inversion to screen for AVO anomalies and to identify and derisk remaining undrilled opportunities. Since the process uses only information present within the seismic data, comparison with the results of extensive drilling provides a true blind test of the effectiveness of the method. Results are presented from the North Sea and Atlantic Margin which demonstrate the effectiveness of the method and highlight some remaining undrilled opportunities.
