Webb1 nov. 2024 · Complex seismic trace analysis is a fundamental tool for seismic attributes analysis (Barnes, 2006). Originally, it was discussed in electrical engineering and signal analysis literature (Gabor, 1946; Bracewell, 1986; Cramér and Leadbetter, 1967; Oppenheim and Schafer, 1975). WebbComplex seismic trace attributes were introduced around 1970 as useful displays to help interpret seismic data in a qualitative way. Balch of Marathon published the first article in the 1971 issue of Geophysics under the title of “Color Sonograms”.
