ABSTRACT

I review optimized implicit finite-difference migration for tilted TI media. The implicit finite-difference scheme is designed by fitting the dispersion relation with rational functions using least-squares optimization. I apply the method to a synthetic dataset. The result shows that the algorithm can handle laterally varying tilted TI media.
