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.
