Seismic Attributes

1. Seismic Attributes by\ Asmaa Mohamed Abdallah Supervision Prof . Dr. Ahmed Sayed Abu El-Ata

2. 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 features f or the interpreter on seismic sections . Locate misinterpretation . Get information on lithology , facies or fluid content. R eservoir characterisation

3. The Historical Prespective Of Seismic Attributes A time line of seismic attribute development

4. Classification of Seismic Attributes Physical Attributes attributes Pre -stack Post-stack attributes Geometric Attributes Dip Like, Azimuth Coherence Curvature Ant Tracking

5. Instantaneous Frequency Instantaneous Phase

6. Seismic time slice Coherence time slice

7. Ant track Seismic

8. Case Study A segment of a seismic section

9. stratal slices

10. A 3D view of the stratal cube extracted from the energy attribute .
