Full-waveform inversion for full-wavefield imaging: Decades in the making

The Leading Edge Journal | Rongxin Huang, Zhigang Zhang, Zedong Wu, Zhiyuan Wei, Jiawei Mei, and Ping Wang © 2021 SEG

Seismic imaging using full-wavefield data that includes primary reflections, transmitted waves, and their multiples, has been the holy grail for generations of geophysicists. To be able to use the full-wavefield data effectively requires a forward modeling process to generate full-wavefield data, an inversion scheme ...
