Vertical Seismic-Profile Data Local Full-Waveform Inversion Based on Marchenko Redatuming

Local full-waveform inversion (FWI) methods use redatumed seismic responses of virtual receivers within the subsurface to build local objective function based on convolution-type representation theorem. The Marchenko method is widely used obtain data. only requires a smoothed velocity model with correct kinematic characteristics for redatuming single-sided reflection However, standard insensitive lateral propagation wavefield. By injecting wavefield along boundary target, modeling produces errors, which affects accuracy FWI. In this paper, more accurate Green’s functions proposed by incorporating vertical profile data (VSP) into calculation process source-receiver redatuming. This allows one laterally propagating waveform, resulting in significant improvement resolution. applied benchmark dataset and compared FWI
