Conclusions

In this chapter I applied the tomography methodology described in Chapters  and to 2 - D dataset. I 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. I hypothesize that much of the remaining moveout is due to 3-D effects, not resolvable by 2-D tomography.
