Not only can arbitrarily oriented cross-sections be extracted from 3-D seismic volumes, horizontal and parallel to horizon slices can also be gnerated. This is a time-slice, a horizontal seismic sectioni, at a travel-time of 2050 ms. The hydrocarbon-water interface at the base of a hydrocarbon reservoir is flat, as it is controlled by gravity. The large black area in the center of this time-slice is a possible flat spot. Workstations are the only way this type display can be made.
