Full-Bandwidth FWI: A Paradigm Change in the Imaging and Interpretation of Seismic Data

Computational and workflow limitations restricted the scope of FWI applications, with the method only using very low frequencies and transmitted arrivals. We have now overcome these limitations and can invert the full bandwidth of the data and include the reflected wavefield. The new, full-bandwidth, high-resolution FWI products have broad utility, beyond merely being used as migration velocity models. In particular: (1) subsurface scales not visible in traditional seismic can now be seen in FWI models; (2)the models are used for improved reservoir characterization and 4D seismic interpretation; (3) the method offers an effective approach for handling novel,non-conventional acquisition geometries and reduce cycle time. At the presentation we will show examples demonstrating the methods and benefits of Full-Bandwidth FWI.
