Abstract
3 signal event is far more aligned after deconvolution has been applied demonstrating that the phase spectrum of the surface consistent distortions have been correctly estimated. msec Figure(1a) CDP gather displaying surface consistent phase rotations and time shifts with added noise Figure(1b) synthetic CDP gather from figure (1a) after surface consistent deconvolution The second example shows the effectiveness of the algorithm when applied to a real land vibroseis data set. Prior to deconvolution inverse Q-filtering deterministic zero phasing refraction statics surface consistent residual statics NMO and a sliding gate amplitude equalization had been applied to the data. The deterministic zero
