Advantages of Shear Wave Seismic in Morrow Sandstone Detection
Figure 22
(a) P-wave impedance map and (b) S1-wave impedance map (right) are shown with well pattern overlaid on them (green dots represent producer wells; red dots represent injector wells). For P-waves, the impedance map is obtained by computing rms amplitude in a 0.009 s window centered on Morrow A sandstone. For S1-waves, the impedance map is obtained by computing rms amplitude in a 0.01 s window centered on Morrow A sandstone [35]. The S1-wave impedance shows better match with the well pattern. The high impedance in the west part of the study area (shown by black oval) ties with the presence of A1 sandstone (Figure 20(b)).
