oa Target-oriented elastic full-waveform inversion through acoustic extended migration redatuming

Elastic full-waveform inversion (FWI) has the potential of simultaneously invert all the scales of the elastic subsurface model while accounting for the elastic effects present in the recorded data. However, its application on production field datasets is limited by its high computational cost. In fact, the computational time of the elastic Green’s functions involved during any data inversion is much higher compared to the cost of the acoustic ones.
