In the same survey area, there exist great differences in phase, power and frequency because of different surface conditions and irregular shooting of controllable vibratory seismic and exploding sources. The authors applied such processing methods as surface consistency, wavelet matching filter and residual static correction to eliminate these differences, with a good seismic profile achieved.
