Incorporating seismic interferometry and full waveform inversion

Jinji Li, Kristopher A. Innanen

Seismic interferometry, through the cross-correlation of data recorded by receiver pairs, can extract Green's function, enabling the potential redatuming of signals using passive datasets. This capability holds promise for integration with full waveform inversion (FWI) to continuously update subsurface property estimates in real time. This report presents a preliminary investigation into the feasibility of combining seismic interferometry and FWI by introducing a novel objective function aimed at mitigating interference patterns in seismic waveforms. A straightforward numerical example demonstrates that, under conventional surface acquisition constraints, seismic interferometry can enhance the estimation of P-wave velocity. However, further comprehensive research is needed to assess the algorithm's performance across diverse scenarios, including elastic applications.
