A B S T R A C T METHOD FOR PROCESSING MARINE SEISMIC DATA Methods are provided for processing seismic data acquired during marine seismic operations when the seismic streamer cables or sources deviate from their desired acquisition track. The method initially processes the data using conventional normal moveout techniques, then applies conventional dip moveout techniques, followed by regularization of the cross-line data, and then 3-D migrating the regularized data. Regularization involves determining the signals at preselected cross-line positions based upon the signals detected and recorded at the measured cross-line CMP positions.
