What is it about?
Full elastic wave-equation based, target-oriented AVO inversion, for reservoir characterisation.

Why is it important?
The fact that the inversion is full elastic wave-equation based means that the inversion can handle internal multiple scattering and mode-conversions over the target interval. It also honours the real travel times in the data, rather than travel times calculated in the smooth background. It also means that the parameters that are inverted for are the compliances that define the wave-equation, rather than acoustic and elastic impedances that are obtained from the reflection coefficient based model.
Perspectives
I feel that this article describes the first real breakthrough in AVO inversion techniques since AVO was invented in the early eighties of the previous century.
