Implementing the Smith/Fatti equation
There are two ways in which we can implement the Smith/Fatti equation:
- Perform a weighted stack of the pre-stack data to extract the three reflectivity terms. These terms can then be inverted independently.
- Simultaneously invert for P-impedance, S-impedance and density by extending our model-based approach.
The mathematics of simultaneous inversion is given in an appendix to this talk.
The next slide describes the method qualitatively.
