Inversion for Geofluid Discrimination Based on Poroelasticity and AVO Inversion

Figure 16

The comparison between the low-pass filtered parameters and the inverted parameters of (a) , (b) , (c) , and (d) density. The blue lines represent the inverted model and the red lines denote the low-pass filtered well log data with a high-cut frequency of 70-80 Hz. The correlation coefficient between the inverted model and the well log data is 0.8924, 0.8567, 0.8824, and 0.8648.
