AB  - We demonstrate that accurate amplitude-vs-angle parameters can be extracted from raw unprocessed seismic data using purely acoustic full-waveform inversion. The resultant parameters incorporate the full elastic response of the observed data, and it is not necessary to use elastic FWI in order to determine AVA. This approach naturally corrects for a multitude of other amplitude effects including reflector geometry and transmission losses, and it deals correctly with near-critical and post-critical reflections. FWI-based workflows are consequently simpler than conventional workflows, and AVA parameters can normally be generated by FWI within days of raw field data first becoming available.
