2D Specular Beam Migration - Enhancing Structural Images in Frontier Areas

The specular beam migration method has been applied successfully in 3D (Cockshott, 2007). In this paper, the method is shown to also work well in 2D. The speed advantage over the Kirchhoff method is not so great in 2D as in 3D; in 2D, it is the signal enhancement ability of the method which is its strength. Here, the specular beam method is applied to real data examples from the North European margin and the results are compared with those of conventional Kirchhoff migration.
