Advantages of Shear Wave Seismic in Morrow Sandstone Detection

Figure 15

P-wave gathers (left), S-wave gathers (center) and PS-wave gathers (right) generated using Models 3a, with changing A sandstone thickness from 0 to 32.5 m. The synthetic gathers show that it is difficult to detect less than 13 m sandstone thickness using P-waves, since the peak doublet is absent. In PS-wave gather, the separate peak response is not present for 13 m of A sandstone thickness. The S-wave gather shows a distinct peak response even for 6.5 m of A sandstone thickness.
