There is probably no single seismic attribute that will always tell us all that we need to know about fracture zones. Therefore, our approach in this project has been to integrate the principles of Rock Physics into a quantitative processing and interpretation scheme that exploits, where possible, the broader spectrum of fracture zone signatures: (1) anomalous compressional and shear wave velocity; (2) Q and velocity dispersion; (3) increased velocity anisotropy; (4) amplitude vs. offset (AVO) response, and (5) variations in frequency content. As part of this we have attempted to refine some of the theoretical rock physics tools that should be applied in any field study to link the observed seismic signatures to the physical/geologic description of the fractured rock. Furthermore, while we have used standard shear wave techniques to process and analyze our field data, our goal in this project has been to explore also non-shear wave methods. The project had 3 key elements: (1) Rock Physics studies of the anisotropic viscoelastic signatures of fractured rocks, (2) Acquisition and processing of seismic reflection field data, and (3) Interpretation of Seismic and well log data.
