Advantages of Shear Wave Seismic in Morrow Sandstone Detection

Figure 17

(a) P-wave gather shows a peak doublet at the top of Morrow A sandstone (1.07 s) which changes to single peak at far offsets. (b) S1-wave gather shows a peak response at the top of Morrow A sandstone (2.08 s) changing to trough with offset. The AVO response in real data P- and S1-wave gathers matches with the synthetic gather AVO response shown in Figures 12(b) and 13(b).
