Conclusions

In this paper we applied our tomography methodology to a 2-D dataset. We showed how to construct a complex steering filter operator based on reflector geometry and a priori knowledge of the acoustic properties of the layers. The final migration result was significantly improved over the initial migration showing flatter angle gathers and overall crisper image. We hypothesize that much of the remaining moveout is due to 3-D effects, not resolvable by a 2-D algorithm.
