Fluid Discrimination Based on Frequency-Dependent AVO Inversion with the Elastic Parameter Sensitivity Analysis
Figure 11
The P-wave difference dispersion factors of different dispersion terms. PDDF indicates the P-wave difference dispersion factor; (a) is the section of PDDF related to Lamé parameter, (b) is the section of PDDF related to bulk modulus, (c) is the section of PDDF related to Russell fluid factor (), and (d) is the section of PDDF related to P-wave velocity. The red circle highlights the location of the gas reservoir. The PDDFs are normalized.
