1. A computer-implemented method of searching and analyzing a seismic data volume acquired in a seismic survey to determine potential for hydrocarbon accumulations in an associated subsurface region, comprising: obtaining surfaces describing the seismic data volume; enumerating the surfaces; selecting at least one enumerated surface; augmenting, by a computer processor, the at least one selected surface when the selected surface does not substantially cover an area associated with the seismic data volume, said augmenting being performed until all selected surfaces substantially cover the area, wherein substantially is judged against a pre-selected criterion; and displaying the at least one selected surface, with geologic or geophysical data associated therewith, for visual inspection or interpretation, or saving digital representations thereof to computer memory or data storage.
