Abstract

Summary

This talk presents a numerical approach for including attenuation in forward seismic viscoacoustic simulators in the time domain using a generalized Maxwell body (GMB). We discuss how to select the proper number of relaxation mechanisms and the values of the parameters of the GMB. We also present a few synthetic case studies determining the feasibility of performing full-wavefield inversion of viscoacoustic media, and the aperture requirements. Finally, field examples are shown where attenuation needs to be accounted for in order to perform a successful inversion.
