Professor Helbig (1980) has dealt with the inversion of seismic reflection data to give a representation of the disposition of reflectors within the earth which give rise to the observed data. The data to which he referred belong to a subset of the total observed data, namely those “horizons” or “events” which the interpreter chooses to “pick”, having sufficiently distinctive and continuous visual properties on the seismic sections to allow him to follow them. This may be both time-consuming and difficult particularly where horizons appear to intersect, or there may be a break in continuity. Synclinal features giving rise to “Bow-tie” patterns are often difficult to follow. Figure 1 shows the seismic response of such a feature. What the interpreter needs is a migration process which can treat all the observations in the seismic section. So today we have a plethora of signal processing methods which purport to invert all the recorded signals, be they reflections or diffractions, and to show their origins in their true positions and strengths.
