Abstract
The method processes input including, for each of a plurality of shots at respective source locations, seismic traces recorded at a plurality of receiver locations. Offset-modulated data are also computed by multiplying the seismic data in each seismic trace by a horizontal offset between the source and receiver locations for said seismic trace. A depth migration process is applied to the seismic data to obtain a first set of migrated data, and to the offset-modulated data to obtain a second set of migrated data. For each shot, offset values are estimated and associated with respective subsurface positions, by a division process applied to the first and second sets of migrated data.
