Window based amplitude slice attribute from amplitude volume or impedance slice from inverted volume may be help full , provided desired facies thickness is more or equal to the limit of seismic resolution.

You can use AVO attributes, energy, soectral decomposition, seismic inversion. They can help.

It seems important to me to say, that if it is a question of seismic attributes oriented to stratigraphic analysis, (“stratigraphic traps are hydrocarbon accumulations independent of structural or fault closure”) in the first place the seismic interpretation itself must be taken into account, that is, an attribute that is derived from the seismic will be influenced by the seismic interpretation. You must guide in your user-defined window, all attribute prediction should be based on a geological seismic interpretation and should be validated by well-logs control. The current access to high-quality 3D seismic has enabled the stratigraphy concepts coin in 1970-80 by a brilliant generation of Geologist and Geophysicist, such as Exxon and Shell´s colleagues. You cannot leave the whole thing in the hands of the software, there must be a stratigraphic concept that accompanies the extraction of the seismic attributes.

Let me stress the concept: It is remarkable how nowadays the new generations of seismic interpreters use the seismic attributes tools, but sometimes without a concept such as a sequential seismic analysis in the classical concept of the term (Mitchum, 1977). Although the methodology of the attribute extraction is relatively easier today, even with or without well control, it does not take into account this crucial aspect for the understanding of its results, in many authors words: “… various post-stack seismic attributes were used, from complex trace and spectral decomposition, for the detection of stratigraphic characteristics of the area of ​​interest ... ”

On the other hand: You must try to make a QC control of your input data: Errors in geometry, statics, wavelet shaping, and velocities all reduce the bandwidth and SNR, acquisition footprint, processing workflow focus in migration, and your own responsibility as Interpreter: abuse of the auto-tracking techniques in the presence of low SNR data degrades the geometry of stratigraphic features, it is an “Interpreter-footprint” that you must understand earlier.

The methods for locating prospective stratigraphic traps by seismic attributes are not a simple methodology. It means I stress the need to use sequence stratigraphy as the framework for data integration.

I recommend, in principle is that an effective stratigraphic trap exploration consists of the following steps:

1. Calibrate key-well-logs and seismic if you have, even trying to understand the rocks and fluids contribution.

2. Apply sequence-stratigraphy analysis in the classical concept in your seismic interpretation, using landmark book: AAPG Memoir 26 “Seismic Stratigraphy: Applications to Hydrocarbon Exploration” edited by Charles E. Payton and originally presented as a research symposium at the 1975 AAPG Annual Conference and Exhibition (ACE) at New Orleans, USA.

3. Analyze seal, reservoir, and show to find and evaluate traps.

4. Apply the seismic attributes in the windows of interest using the guide of the book “Seismic Attributes for Prospect Identification and Reservoir Characterization” by Chopra and Marfurt (SEG Geophysical Developments Series No. 11, Stephen J. Hill, editor, 2007, Society of Exploration Geophysicists).

You can enhance your recognition of stratigraphic features by using seismic data attributes, such as reflection strength, coherence, and instantaneous phase. These attributes are well suited to stratigraphic interpretation and are an effective interpretive tool when displayed in map view, but today there is a proliferation of seismic attributes such as pattern recognition analysis, texture attributes, spectral decomposition, seismic inversion, AVO.

Also, I attached a simple Chart of Petrel seismic data attributes and their use in seismic facies analysis.

If you have any other questions, please, let me know.

Mario Emilio Sigismondi ! you have explained entire process in very details so nicely, probably it will help users alot. Without well calibrated, attribute derivation is always misleading to users even in simplest geological area of target exploration. Geologically complex area will give entirely different results even in very closed proximity to well.
