3D Migration of a Simulated Wide-Azimuth Towed Streamer Survey

A 3D synthetic wide-azimuth towed-streamer (WATS) dataset is migrated with different migration techniques. These migration techniques are suited for imaging complex overburden. First, a wave-equation method based on a oneway propagator is used. Second, a two-way method that utilizes one-way propagators for the wavefield extrapolation downward and upward is tested. Finally, a method based on the solution of the two-way acoustic wave equation, also known as Reverse Time Migration (RTM) is selected.
