Least‐squares inversion of seismic reflection waveform data can reconstruct remarkably
detailed models of subsurface structure and take into account essentially any physics of …

Full waveform inversion (FWI) is a powerful method for reconstructing subsurface
parameters from local measurements of the seismic wavefield. This method consists in …

We present a finite-difference frequency-domain method for 3D visco-acoustic wave
propagation modeling. In the frequency domain, the underlying numerical problem is the …

Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by
solving an inverse problem based on seismic measurements. There are at least three …

Elastic full-waveform inversion is an ill-posed data-fitting procedure that is sensitive to noise,
inaccuracies of the starting model, definition of multiparameter classes, and inaccurate …

Classical algorithms used for traveltime tomography are not necessarily well suited for
handling very large seismic data sets or for taking advantage of current supercomputers …
