Seismic interpretation of stratigraphy and sedimentology is frequency and scale dependent. Frequency dependency offers a new dimension of seismic data that has not been fully utilized in the study of seismic facies and seismic sedimentology/geomorphology. Zero-offset seismic events are a function of a wavelet and an acoustic impedance profile. Seismic interferences, controlled mainly by thickness- and frequency-tuning effects, exert significant influence on the occurrence of seismic events and types of seismic facies. By analyzing an amplitude-versus-frequency plot or panel-filtering seismic data, we can intentionally modify seismic events and seismic facies to a certain degree to better integrate well and seismic interpretation.
