f Seismic imaging in anisotropic media

Seismic velocity anisotropy in exploration geophysics has been widely observed and multicomponent data associated with it cannot be explained by isotropic models. The presence of anisotropy is commonly neglected in the imaging of seismic data and only few attempts have been made to incorporate the effects of anisotropy. In order to image the subsurface properly, when a significant degree of anisotropy is present, the imaging procedures must handle the anisotropy correctly. We develop an algorithm to perform Kirchhoff migration in anisotropic media. The scheme is applied to the case of azimuthal isotropy. Analytical expressions for the ray amplitudes and traveltimes are used to generate a suitable Green's tensor for migration .
