From well data to a complete description of a reservoir using geostatistical methods

The use of new coneepts in sedimentological interpretation (stratigraphic sequences, carefully done deseription of the cores...) combined with new tools in geostatistics (variograms, proportion curves...) allows to characterize the size and the frequency of sedimentary bodies and of their internal heterogeneities. The geological interpretations and constraints appear to be crucial prerequisites for the consistency of the method.
