Figure 7. Seismic character transition and zones of deformation style including decollement surface slumping and canyonization. (A) A two-dimensional (2-D) aerial view of a top reservoir seismic extraction surface showing the location of low-amplitude anomalous zones and their relationship to the interpreted fault network. (B) A close-up 2-D aerial view of the top reservoir (decollement because reservoir is not present) extraction surface showing interpreted extensional faults within a low-amplitude feature. (C) A seismic section through the feature shown in (B), showing the location of small extensional faults that allow deformation of the decollement surface. (D) A seismic section showing four zones of deformation style across the reservoir and decollement surface area. The insert shows the four zones in schematic style. (E) A top reservoir two-way time (TWT)–structural surface showing slope canyonization on the eastern flank of the Melville Bay ridge. Topographically controlled shed reservoir sediment is depicted deposited within the canyons as a filtered root-mean-square (RMS) amplitude surface. The locations as seen in (A) and (E) are shown in Figure 5.
