Abstract
The method uses the image obtained by accumulating continuity curves representative of seismic horizons so as to determine the geological strata constituting the seismic section, such as they were deposited and not such as they are observed today. To do this, the method defines a transformation of the vertical scale of the seismic section, scale measured in seismic times, into a geological vertical scale measured in geological times. This transformation is based on an equalization of histograms. Starting from equalized histograms, the method makes it possible to determine equalized seismic sections which are used to determine the rates of sedimentation which governed the depositions of geological strata. In particular, it highlights geological hiatuses, that is to say erosions and gaps.
