Video Summary
The presence of natural fractures and in situ stress induces anisotropic seismic response that is neglected in many cases of interest for petroleum geophysics, due to its complexity and subtlety. As a result, isotropic prestack inversion has become a more widely applied methodology than its anisotropic counterpart.

Nevertheless, most natural sediments, through their deposition and stress, will exhibit some degree of anisotropy, and ignoring its effects while estimating rock physics properties may lead to biased results.

You may either want to estimate the anisotropy itself or make sure your seismic and inversion attributes are not biased by the anisotropic character of the earth.

In this video, industry-expert Peter Mesdag, covers seismic forward modeling and inversion using isotropic formulas in anisotropic media. We extend the conversation of a published CGG GeoSoftware article from the November issue of The Leading Edge's Special Topic on Reservoir Characterization titled: "Quantitative Inversion of Azimuthal Anisotropy Parameters from Isotropic Techniques
