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

Figure 12

Display of various parameters at the well location. (a) is the poststack seismic trace; (b) is the P-wave velocity, the red curve is the real well log after smoothing, and the blue curve is the inverted result; (c) is the dispersion term of Lamé parameter (); (d) is the dispersion term of bulk modulus (); (e) is the dispersion term of Russell fluid factor () (); (f) is the dispersion term of P-wave velocity (); (g) is the PDDF of Lamé parameter (); (h) is the PDDF of bulk modulus (); (i) is the PDDF of Russell fluid factor () (); (j) is the PDDF of P-wave velocity (). The yellow dotted rectangle highlights the location of the gas reservoir.
