Because least-squares wave-equation migration/inversion accounts for illumination mismatches--caused by differences in acquisition geometries--and for band-limited wave-propagation effects, it provides images with improved resolution and better definition of seismic amplitude changes.
Using subsets of the Valhall LoFS data, we showed that this method can be used to attenuate artifacts caused by obstructions in the acquisition geometries.
