f Wavelet Estimation and Multiple Modeling in Full-Waveform Inversion

Full-waveform inversion (FWI) has the potential to extract information not only from primary reflections, but also from multiples. We show that accurate modeling of multiples provides strong constraints on the amplitude, frequency spectrum and phase of the seismic wavelet. Thus the method presented here leads to a very robust estimation of the wavelet without relying upon well control. As a consequence, it is applicable to and could be particularly beneficial to the early stages of exploration.
