Imaging the Morrow A Sandstone Using Shear Wave VSP Data, Postle Field, Oklahoma

Figure 15

Zero-offset compressional (a) and (c) and shear (b) and (d) wave data before and after deconvolution. The green arrows show the Morrow A sandstone level, and the red arrows point to the Atoka limestone. Qualitatively, both datasets have similar temporal resolution, but the Morrow A event is more distinctive in the shear wave data than in the compressional wave data.
