Perhaps at this point we can insert a few further comments about nature and nurture. Seismology is concerned with the physics of wave propagation through the earth. The actual recorded seismic waves, before any processing, contain the greatest amount of information about this physical phenomenon. A petroleum geologist, however, is interested in a picture of a cross section of the earth. The painting of a good picture requires a significant element of art. The whole purpose of data processing is to discard the strictly physical picture of wave propagation and replace it by a more artistic rendition of the geology. If the artwork is done properly, interpreters can look at this picture and see the geology with their own eyes. The ultimate goal of digital processing is to relieve the geologist from having to worry about wave propagation effects; these effects should be corrected as much as possible to produce a clearer picture of the subsurface. Nature gives us the recorded seismic traces, but nurture, in the form of deconvolution, stacking, wavelet processing, and migration, provides the final geologic picture. The discipline known as seismic stratigraphy attests to the efficacy of seismic-processing methods that are designed to satisfy these criteria.
