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
