Abstract
Summary
FWI run to full bandwidth can remove multiples and ghosts from raw field data. Differentiation of the resultant high-resolution velocity model then allows the generation of a full-bandwidth PSDM reflectivity image without conventional processing or migration. We have run FWI to 100 Hz on raw field data from a marine towed-streamer dataset. We show that the results are similar to, and are broader bandwidth than, conventionally processed PSDM images. When run on the public cloud, this approach allows the production of final full-bandwidth PSDM volumes within in a few days of completion of data acquisition.
