1. A method for stratigraphic analysis of seismic data, comprising: (a) selecting a seismic data volume comprising a plurality of samples; (b) selecting a number of horizons within the seismic data volume; (c) selecting a scale of interest within the seismic data volume, which ranges from at least 500 meters up to the size of the entire seismic data volume; (d) applying an attribute function to at least one of the selected number of horizons at the selected scale of interest; and (e) displaying a stratigraphic attribute which represents a geologic feature as a result of applying the attribute function at the selected scale.
