A technique for use in towed-array, marine seismic surveys includes a method and an apparatus. The method includes accessing a set of multicomponent seismic data acquired in a wide tow, marine seismic survey; and interpolating a set of seismic data from the acquired seismic data in the crossline direction such that the combined acquired and interpolated seismic data meet the discrete spatial sampling theory requirements for array detection of broadside seismic signal and the discrimination and suppression of broadside linear noise. In some aspects, the technique includes programmed storage media and/or programmed computers for use in executing such a method. The apparatus is a wide tow array, including a plurality of streamers spaced apart by a cable separation exceeding the maximum cable spacing for array detection of broadside seismic signal and the discrimination and suppression of broadside linear noise as determined by discrete spatial sampling theory.

Wide tow enabled by multicomponent marine seismic cable

A method includes: interpolating a set of crossline seismic data from a set of acquired multicomponent seismic data; predicting a multiple in the interpolated and acquired seismic data from the combined interpolated and acquired multicomponent seismic data; and suppressing the predicted multiple. Other aspects include a program storage medium encoded with instructions that, when executed by a computing device, perform such a method and a computing apparatus programmed to perform such a method.
