oa The Khuff Impact on Unayzah Seismic Response: Umm-Jurf Field

The combined effects of variations in thickness and impedance in the Khuff Formation are significant and are sources of noise in the seismic image of the Unayzah Formation in the Umm Jurf Field. They obscure important reservoir signals and degrade the accuracy of the depth and thickness maps. The influence of these variations is readily seen on seismic time and horizon slices.
