Paper Number: SEG-2009-3705
... migrated traces are processed independently using complex trace analysis in order to facilitate this procedure. The instantaneous phase is of central importance since it describes the lateral continuity of events and defines instantaneous dips corresponding to instantaneous apparent phase velocity and...

... through Fourier transform. Complex trace analysis is a transform technique which separates the physical characteristics of the waveform that may have significant information about the local geology. It effects a natural separation of amplitude and phase information. The amplitude attribute is called...

Method Complex seismic trace analysis represents seismic data as the product of two attribute functions, amplitude and phase (Taner et al., 1979). Amplitude and phase are the fundamental attributes from which all others are derived. Derived attributes...
