Mitigating the gradient artefacts of Migration Velocity Analysis by Gauss-Newton update
Mitigating the gradient artefacts of Migration Velocity Analysis by Gauss-Newton update
Full waveform inversion (FWI) is a method of velocity estimation which minimizes the misfit between recorded and modeled data, the parameters of the minimization being the velocity model. If the velocity model is smooth, then only the refracted waves are modeled and used, if ...
