Abstract
Summary
Over the years Shenzi field in deep-water Gulf of Mexico became a test bed for evaluation of new seismic acquisition and processing technologies. These include 3D narrow azimuth streamer data, 3D-rich azimuth streamer data, and recently 3D OBN data (Mifflin et al, 2021). On the processing side, many types of processing techniques were used to image the various data types recorded over Shenzi field, from 3D ray-based Kirchhoff summation PSDM to Acoustic RTM PSDM and Acoustic FWI imaging. In the work presented here we demonstrate the advantages of Full Elastic imaging using the OBN dataset acquired by Woodside Energy in 2019 to better image the sub-salt field.
