Fluid Discrimination Based on Frequency-Dependent AVO Inversion with the Elastic Parameter Sensitivity Analysis

Figure 7

The results of FAVO inversion. indicates the dispersion term. (a) is the section of dispersion term of Lamé parameter, (b) is the section of dispersion term of bulk modulus, (c) is the section of dispersion term of Russell fluid factor, and (d) is the section of dispersion term of P-wave velocity. The red circle highlights the location of the gas reservoir. The dispersion terms are normalized.
