We are currently working on a way to generate angle-domain CIGs with Kirchhoff migration and multiple arrival traveltimes. The angle domain's ability to prevent multipathing should allow cleaner results in areas with complex subsurfaces.
We also intend to explore the use of angle-domain CIGs in shadow zones. Theoretically, reflection angle gathers have a more equalized amplitude versus angle panel than offset gathers have for their amplitude versus offset panels. Therefore, studying areas of low illumination in the angle domain should yield more continuous reflectors.
