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

Figure 14

A synthetic zero-offset VSP shot gather was generated to compare the results after wavefield separation using median filter and dual median filter. (a) shows the synthetic upgoing wavefield, and (b) represents the synthetic zero-offset VSP shot gather after stacking with the downgoing wavefield. (c) and (d) depict the calculated residual amplitude (original upgoing wavefield-separated upgoing wavefield) after wavefield separation using median filter and dual median filter, respectively.
