1. A method, comprising:
automatically selecting a first plurality of seismic attributes corresponding to seismic data as first selected seismic attributes;
combining the first selected seismic attributes into a first realization of attributes;
automatically selecting a second plurality of seismic attributes corresponding to the seismic data as second selected seismic attributes;
combining the second selected seismic attributes into a second realization of attributes;
performing a first cluster analysis on the first realization of attributes to generate a first clustered volume;
performing a second cluster analysis on the second realization of attributes to generate a second clustered volume;
selecting a region of interest (ROI) in the seismic data;
projecting the ROI onto the first clustered volume to generate a first signature;
projecting the ROI onto the second clustered volume to generate a second signature;
determining a first level of correlation between the ROI and the first signature;
determining a second level of correlation between the ROI and the second signature;
determining whether the first level of correlation between the ROI and the first signature exceeds a predetermined threshold and outputting a first correlation volume corresponding to the first signature when the first level of correlation between the ROI and the first signature exceeds the predetermined threshold; and
determining whether the second level of correlation between the ROI and the second signature exceeds the predetermined threshold and outputting a second correlation volume corresponding to the second signature when the second level of correlation between the ROI and the second signature exceeds the predetermined threshold.
