Paper Summary
Creating images from high-resolution FWI models by taking some form of the spatial derivative of the velocity has quickly become a popular way to generate reflectivity images, typically called FWI Imaging. FWI imaging offers the possibility of high-quality and high-resolution in a more simplified workflow compared to the conventional processing, model building and imaging workflow. Such images are being increasingly used as alternatives or even replacements of the conventional, or least-squares, Kirchhoff and RTM products.
Using data examples of FWI imaging we demonstrate its benefits; after drawing conclusions we
consider some of the challenges of working with FWI imaging that have formed the basis of ongoing or recently completed work.
