Abstract:
A method for using one or more seismic trace volumes to identify a real trends of multiple seismic attributes along a subsurface horizon, said method comprising:a) selecting a representative subset of traces from said seismic trace volume, wherein said subset of traces intersects said horizon;b) comparing the full waveform of each trace in each said subset of each trace volume to every other trace in said subset over predefined zones above and below said subsurface horizon to determine a similarity factor for each trace with every other trace in said subset of traces,c) separating traces in said subset into a number of waveform classes based on variance of said similarity factor for traces in said subset; andd) grouping traces in said subset according to said waveform classes, wherein display of traces according to said waveform classes reveals a real trends of multiple seismic attributes.
