Abstract
The present invention is a method for exploiting a sedimentary basin using an updated stratigraphic model based on updating a stratigraphic model according to measurements performed in a basin. The method comprises steps of i) determining at least a first spatial distribution of the values of an attribute representative of the basin stratigraphy, and applying a classification method for converting this first spatial distribution to a first classified image; ii) performing a stratigraphic simulation with first parameter values of the simulation, deducing therefrom a second spatial distribution of the values of the attribute and applying the same classification method identically to determine a second classified image; iii) determining a distribution of local dissimilarities between the first and second classified images, and modifying the values of at least one of the stratigraphic simulation parameters to minimize an objective function formed from at least the local dissimilarity distribution; and iv) updating the stratigraphic model by performing at least one stratigraphic simulation with the modified simulation parameter values.
