Abstract
The present invention is directed to a method and system for minimizing artifacts in a seismic image of a subsurface region of interest, wherein the image is determined a data beam set derived from recorded seismic data and a modeled beam set derived at least in part from a velocity model related to a subsurface region. The artifacts, which may result from cycle skipping and coherent noise, result in misalignment of the modeled and data beam sets. The present invention utilizes a Monte Carlo inversion technique to update the velocity model and thus minimize the artifact in the seismic image.
