Abstract
A method for forming an image of a subterranean region of interest, using an observed seismic dataset, a seismic velocity model and a simulated seismic dataset based in part, on the seismic velocity model is provided. This method includes forming trace pairs from the simulated and observed seismic dataset, wherein each of the trace pairs comprises of an observed trace and a simulated trace. An objective function is formed based on a penalty function and a phase cross-correlation between the observed and simulated seismic trace of each of the trace pairs. This method further includes determining an extremum of the objective function and a seismic velocity increment based on the extremum. The seismic velocity model is updated by combining the seismic velocity increment and the seismic velocity model and the image of the subterranean region of interest is formed based in part, on the seismic velocity model.
