Full waveform inversion has shown its huge potentials in recovering a high‐resolution
subsurface model. However, conventional full waveform inversion usually suffers from cycle …

The main difficulty with iterative waveform inversion is that it tends to get stuck in local
minima associated with the waveform misfit function. To mitigate this problem and avoid the …

Full-waveform inversion requires the accurate simulation of the dynamics and kinematics of
wave propagation. This is difficult in practice because the amplitudes cannot be precisely …

By taking advantage of the information carried by the entire seismic wavefield, Full
Waveform Inversion (FWI) is able to yield higher resolution subsurface velocity models than …

Extracting true amplitude versus angle common image gathers is one of the key objectives
in seismic processing and imaging. This is achievable to different degrees using different …

While traditional ray-based techniques are inadequate for building salt geometry and sub-
salt velocity models, wave equation based methods, such as Wave Equation based …

Résumé L'imagerie sismique est l'une des méthodes les plus effectives pour estimer les
paramètres physiques de la Terre à partir de données sismiques. Sous l'approximation …

Seismic imaging is one of the most effective methods for estimating the Earth's physical
parameters from seismic data. Based on the assumption of scale separation, several …
