A method of geophysical exploration in a seismic survey includes acquiring a set of seismic traces based on seismic data obtained by a seismic receiver, responsive to seismic energy reflected from a subsurface geology. Additional steps include performing reverse time migration on the seismic traces using a velocity model that represents velocity of the seismic energy propagating through the seismic medium. The migrated gathers have an amplitude based at least in part on the migration, which can be corrected by computing synthetic seismograms to provide compensated gathers. Amplitude versus offset and/or amplitude versus angle analysis can be performed on the compensated gathers, in order to generate a seismic image of subsurface structures in the survey area.
