Layering Anisotropy<br />
This will be present in all sedimentary<br />
basins. Anisotropy results from the<br />
contrasting layers, from the intrinsic<br />
anisotropy within layers, from<br />
superimposed fractures, and from stress<br />
differences.<br />
Intrinsic fabric anisotropy<br />
(e.g.shale) tends to dominate<br />
over the layering effect.<br />
The Backus Average is our<br />
primary rock physics tool for<br />
layered systems<br />
