Time-frequency analysis of seismic sequences.
Proceedings of the 65th SEG Meeting, 1995.
Abstract: Reflection patterns play an important role in seismic sequence
stratigraphy, therefore making their quantitative description
essential for the construction and validation of sequence
stratigraphic models from seismic data. The characteristics of a
seismic reflection pattern can be elicited from the data by
representing the data as a joint function of time and frequency.
Developments in the field of time-frequency analysis have led
to t-f representations with better resolution than can be
obtained with classical methods for local frequency analysis.
This justifies a study of the application of these new
representations to the analysis of seismic data. Some examples
of the t-f representation of the seismic response of layered
sequences are given. They clearly show the contribution of the
stratigraphic sequence to the spectral content of the data.
The construction of a sequence stratigraphic model from a
t-f representation is demonstrated with a field data
example where we match a pattern that was observed in the
data to a sequence model.
