Three-dimensional frequency-domain full waveform inversion (FWI) of fixed-spread data can be efficiently performed in the visco-acoustic approximation when seismic modeling is based on a sparse direct solver. We present a parallel algebraic Block Low

International audience; For efficient frequency-domain full wave inversion (FWI), frequency-domain solutions of the wave-equation are required. The wave equation can be solved by direct or iterative solvers in the frequency domain or, alternatively,
