Imaging the Morrow A Sandstone Using Shear Wave VSP Data, Postle Field, Oklahoma
Figure 4
Synthetic gathers made for different thicknesses of the Morrow A sandstone in Postle Field. Compressional wave gathers (a) and (c), nonconverted shear wave gathers (b) and (d) for 13 m (a) and (b) and 6.5 m (c) and (d) thicknesses of the Morrow A sandstone. The synthetic gathers show that it is difficult to detect less than 13 m sandstone thickness using P-waves, because the peak doublet is absent. The nonconverted shear gather shows a distinct peak response even for 6.5 m of the Morrow A sandstone thickness [10].
