Inversion for Geofluid Discrimination Based on Poroelasticity and AVO Inversion

Figure 7

The comparison between the inverted fluid modulus with our method and the method of Zong et al. [26] from the noise-free angle gather. The left subplot (a) displays the variation of porosity with time, the middle subplot (b) shows the inverted fluid modulus with our method (red dashed line) and the true fluid modulus (blue solid line), and the right subplot (c) shows the inverted fluid modulus with the method of Zong et al. [26] (red dashed line) and the true fluid modulus (blue solid line).
