Abstract
The process for analyzing a two-dimensional seismic cross-section image, including traces of a seismic cross-section, including processing the two-dimensional seismic cross-section with a binary function, a first value being assigned if a slope of the amplitude of the trace is positive, and a second value being assigned with a slope of the amplitude of the trace is negative, applying edge following techniques to the binarized image in order to determine contours of areas to be associated based on the first and second values, breaking down each of the contours into a series of chains, limited by turning points situated on each of the contours at a location where a direction changes from left to right or from right to left, when the contour is described in a given direction of rotation, breaking down each chain into contiguous curved segments such that a greatest distance between one point of each contiguous curved segment and a straight line segment joining the two ends the contiguous curved segement does not exceed a predetermined value, allocating to the contiguous curve segments at least one range, characterizing all the values of a parameter associated with the contiguous curved…
