In the case of a complex subsurface single-arrival Kirchhoff migration results can be inadequate. In this work we address the issue of implementing true amplitude multi-arrival Kirchhoff migration with equalization in the angles domain starting from a single arrival algorithm. We develop a method to implement multi-arrival Kirchhoff migration with equalization in the angle domain. We solve wavefront separation by applying a continuity condition and we show that the hit-count panel used for equalization in the multiarrival case is the summation of the single-arrival hit-count. Results on synthetic data prove that multi-arrival migration improves imaging in the case of complex velocity model.

Abstract

In the case of a complex subsurface single-arrival Kirchhoff migration results can be inadequate. In this work we address the issue of implementing true amplitude multi-arrival Kirchhoff migration with equalization in the angles domain starting from a single arrival algorithm. We develop a method to implement multi-arrival Kirchhoff migration with equalization in the angle domain. We solve wavefront separation by applying a continuity condition and we show that the hit-count panel used for equalization in the multiarrival case is the summation of the single-arrival hit-count. Results on synthetic data prove that multi-arrival migration improves imaging in the case of complex velocity model.
