Claim:
1. A method for generating an image of a subsurface formation, the method comprising: receiving first seismic data associated with a base seismic survey of the subsurface formation; acquiring second seismic data during a monitor seismic survey of the subsurface formation, wherein the monitor seismic survey is performed later in time and with different shot-receiver locations than the base seismic survey; estimating subsurface reflection-points and incidence angles for traces in the first seismic data and in the second seismic data; binning the first seismic data and the second seismic data so as to gather the traces of the first seismic data and of the second seismic data, in 4-dimensional (4D) bins determined based on the estimated reflection-points and incidence angles; and processing the 4D bins to generate the image of the subsurface formation.
