Direct Probabilistic Inversion: Adding back Geology into Geophysics through Probabilistic Inversion extended to accommodate Anisotropy in Quantitative Interpretation
The subsurface information obtained from standard AVO inversion is highly ambiguous as different lithologies and fluid configurations result in similar elastic responses. This is an intrinsic characteristic of the ill-posed non-uniqueness of the inversion problem that can be mitigated by integrating relevant and non-redundant information into the inversion process.
