Converted-Shear and Compressional Images Using Projection Imaging

F-31 CONVERTED-SHEAR AND COMPRESSIONAL IMAGES USING PROJECTION IMAGING Abstract I demonstrate how a simple wavefield projection operator inside the kernel of the migration process enables the generation of separate compressional and shear waves images from the same dataset without the need for any additional wavefield separation processing. For compressional imaging this operator projects the multicomponent data on to the ray connecting the receiver to the image point and for shear imaging the operator projects perpendicular to this in the vertical plane for vertical shear and in the horizontal plane for horizontal shear. The method is applied to a two-component synthetic
