What is Seismic Attributes? Seismic attributes are all the information

obtained from seismic data, either by direct measurements or logic or by experienced-based reasoning.

Why do we generate Seismic Attributes ?

To Enhance structural and stratigraphic featuresfor the interpreter on seismic sections.

Locate misinterpretation . Get information on lithology, facies or

fluid content. Reservoir characterisation
