Figure 11

Fig. 11. Ray-trace "illumination" models of N-S vs. E-W acquisition, with corresponding amplitude maps from the corresponding velocity corrected migrations shown beneath. Light areas indicate good illumination, darker areas represent areas where few raypaths (or none) can image the horizon. While the 1989 data show attenuation trending only NW to SE, the 1995 data also shows a pronounced NE-SW line of attenuation over the SE flank of the reservoir.
