1. A method for seismic imaging, the method comprising:
obtaining a combined seismic dataset including shallow profile seismic data and deep profile seismic data, the shallow profile seismic data being acquired using acquisition equipment during a traverse of a survey area, the deep profile seismic data being acquired simultaneously with the shallow profile seismic data during the traverse of the survey area, the acquisition equipment including a plurality of seismic sources having a plurality of positions relative to the survey area, the plurality of positions of the plurality of seismic sources being non-uniform and non-random; and
generating a two-dimensional (2D) deep seismic dataset and a 2D shallow seismic dataset by de-blending the combined seismic dataset.
