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

Figure 6

Inversion results based on the exact Zoeppritz’s equation. (a) is the section of P-wave velocity, (b) is the section of S-wave velocity, and (c) is the section of density. The real well logs are inserted at CDP 330. The red circle highlights the location of the gas reservoir.
