FWI for elastic media: macrovelocity reconstruction

Proceedings, 2017
Currently the common approach to perform FWI is nonlinear least square minimization of the standard data misfit functional which characterizes L2 residual between observed data and synthetized one for a current velocity model. As was aforementioned this approach has been developed and studied in a great number of publications.

The evolution of FWI and its perceived benefits

The APPEA Journal, 2019
Despite the mathematics behind full waveform inversion (FWI) being published in the early 1980s, it was 30 years before the method could be efficiently implemented on the scale of conventional 3D marine seismic volumes. FWI has evolved from using only transmitted waves and being constrained because towed streamer data lacked the very long offsets and ...
