Advantages of Shear Wave Seismic in Morrow Sandstone Detection
Figure 12
(a) P-wave gather for Model 1a shows a Class II AVO anomaly at the top of Morrow A sandstone where a small peak changes into trough with offset. (b) The P-wave gather for Model 3a shows that the peak at the top of Morrow A sandstone is interfered with the side lobe of Morrow shale and bottom limestone layer. This gives a peak doublet at near offsets which changes to a single peak at far offsets.
