International audience; We assess 3D frequency-domain acoustic full-waveform inversion data as a tool to develop high-resolution velocity models from low-frequency global-offset data. The inverse problem is based on a classic gradient method. Inversi

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 resolution of a large sparse system of linear equations whose right-hand side ter
