[OpendTect_Users] Information regarding some frequency attribute

[Paul de Groot]

Hello Shantanu,

Thanks for your question.

Absorption Quality Factor returns the area beyond the dominant frequency
weighted by frequency. The attribute shows how fast high frequencies are
absorbed. The attribute is especially useful in detecting hydrocarbon
anomalies (anomalous behavior shows up below the hydrocarbon-bearing zone).
Normalization is used to enable comparison of absorption effects
independent of seismic energy levels.

Please note that all open source attributes are described in Appendix A of
the OpendTect v4.6 user documentation. For dip-steered attributes
(curvature, dip-steered similarity etc), please see the dGB plugins user
doc. To see what is written about Absorption Quality Factor (described
under Frequency attributes), please see:
http://opendtect.org/rel/doc/User/base/appendix_frequency.htm.

Also, I would like mention the OpendTect Attribute Matrix here as a good
source for attributes and their applications:
https://opendtect.org/opendtect_attributes_matrix/ .

I hope this helps.

Best regards,

Paul.
