The gravity-flow sandstone reservoirs within the field were transported from the north, southward into the East Breaks 160-161 minibasin (Figure 4-40), where the mapped pattern of the ''Glob alt'' sandstones show elongate and lobate north-to-south geometries (Figure 4-49). These north-to-south depositional geometries are draped over the east–west down-to-the-north rollover anticline, resulting in a seismic reflection amplitude pattern that shows north-to-south flank structural downdip termination (Figure 4-57C). East-to-west reflection amplitude termination is stratigraphically controlled by sand distribution. This petroleum-associated reflection amplitude pattern is in contrast to that for sheet sands that would drape over the entire structure and show four-way downdip structural termination of seismic reflection (Figure 4-57D).
