Abstract: A method is described for seismic imaging that receives a field seismic dataset and a synthetic seismic dataset wherein the synthetic seismic dataset is generated with no or known attribute variation with angle or other spatial coordinates; applies seismic processing to the field seismic dataset and the synthetic seismic dataset to generate a processed field seismic dataset and a processed synthetic seismic dataset wherein the processed field seismic dataset and the processed synthetic seismic dataset each contain attribute distortion due to the seismic processing; and corrects the attribute distortion in the field seismic dataset based on the distortion assessed from the processed synthetic seismic dataset to generate a corrected processed field dataset. The method may be executed by a computer system.
