1. A method for assisting with the identifying hydrocarbon deposits comprising: performing a structural interpretation of a three-dimensional seismic volume; transforming the three-dimensional seismic volume into a stratal-slice volume; performing a stratigraphic interpretation of the stratal-slice volume which includes the extracting of bounding surfaces and faults; transforming the stratal-slice volume into the spatial domain; and transforming the bounding surfaces into the spatial domain.
