f The generalised primary and its wavelet transform

All seismic processing techniques are based on the starting point that seismic waves inherit information of certain material properties of the earth's subsurface. From both well and seismic measurements it is evident that the earth's subsurface can be subdivided into a few main stratigraphic sections. The trend in and throughout these intervals gives information on the compaction proporties of the subsurface. The remaining detail displays an irregular behaviour and gives information on the local proporties of the subsurface (within the resolution of the measurements) .
