Figure 2. The same data exhibited on Figure 1 after cross-equalization operators determined at station 153 are applied along the complete air-gun source profile to create equivalent basic wavelets in both the air-gun and shot-hole data. The wavelet character at junction point 165 is now almost seamless. When this type of cross-equalization operator is applied to extensive grids of intersecting seismic profiles acquired with different sources, the consistent imaging wavelets produced in the overlapping data allow a better interpretation of subsurface geology to be done across a prospect area.
