Abstract
Methods and systems are disclosed for forming an image of a subterranean region of interest. The method includes receiving an observed seismic dataset and a seismic velocity model for the subterranean region of interest, and generating a simulated seismic dataset based on the seismic velocity model and the geometry of the observed seismic dataset. The method further includes determining a transformed observed seismic dataset by applying a nonlinear amplitude transform to the observed seismic dataset and determining a transformed simulated seismic dataset by applying the same transform to the simulated seismic dataset. The method still further includes forming an objective function based on the transformed observed seismic dataset and the transformed simulated seismic dataset, and determining an updated seismic velocity model based upon finding an extremum of the objective function.
