Subsalt imaging by common-azimuth migration

ABSTRACT

The comparison of subsalt images obtained by common-azimuth migration and single-arrival Kirchhoff migration demonstrates the potential of wave-equation migration when the velocity model causes complex multipathing. Subsalt reflectors are better imaged and the typical Kirchhoff artifacts caused by severe multipathing disappear. A detailed analysis of common-azimuth images indicates that the results of common-azimuth imaging could be improved. It points to opportunities to improve the numerical implementation as well as the downward continuation method.
