Imaging complex structures with semirecursive Kirchhoff migration
1997
Geophysics
I present a semirecursive Kirchhoff migration algorithm that is capable of obtaining accurate images of complex structures by combining wave-equation datuming and Kirchhoff migration. The method is successful because breaking up the complex velocity structure into small depth regions allows traveltimes to be calculated in regions where the computation is well-behaved and where the computation corresponds to energetic arrivals. The traveltimes computed in such a region are used first for imaging
