Imaging the Morrow A Sandstone Using Shear Wave VSP Data, Postle Field, Oklahoma
Figure 17
(a) S11 RMS amplitude map from the surface seismic data around well HMU 13-2. (b) S11 RMS amplitude map from the VSP data around well HMU 13-2. On both maps, there are two high-amplitude anomalies (white and blue circles). The white circle is on the edge of the VSP map where data are noisy and not reliable. But the blue circle highlights a coherent high amplitude area on both maps. The red circle shows high amplitude on the VSP data, but it is recognizable on the surface seismic data. Most likely, this high amplitude area (red circle) in the VSP data does not correspond to a geologic feature.
