Webb2. Complex Trace Analysis . Conventional seismic trace can be viewed as the real component a complex trace which of can uniquely be defined under usual conditions. The technique allows the separations of envelop amplitude and phase information, and the computation of instantaneous frequency [1]. Trace analysis treats a seismic trace, 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”.

WebbThis is done through a process called binning, by dividing the 2D line range or the 3D survey area into a number of equal-sized CMP bins and, for each bin, collecting those traces whose midpoints fall within the bin as the CMP gather of this bin. The number of traces, or midpoints, within each CMP bin is called the fold. As an important seismic
