The signal-to-noise ratio (S/N) of seismic reflection data in many areas is rather poor and, in addition, a conventional 2D survey has its own artifacts. Due to great advances in ac-quisition of 2D marine data, some of those artifacts can be overcome. However, not all problems can be solved by acquisition methods. Fortu-nately, some can be overcome with further enhancement of the data in the processing center.
