Les images sismiques tridimensionnelles constituent la principale source d'information dans la géomodélisation des réservoirs pétroliers. Nous proposons ici plusieurs algorithmes, implémentés dans le géomodeleur gOcad, pour automatiser leur interprétation, longue et difficile. Une approche continue du signal sismique nous permet tout d'abord de disposer d'une bibliothèque d'attributs sismiques. Deux méthodes de combinaison de ces attributs sont ensuite étudiés: l'une basée sur l'A.C.P. et les nuées dynamiques, pour obtenir des faciès sismiques; l'autre, entièrement nouvelle, basée sur des cartes d'interpolation, pour le calcul des méta-attributs. Enfin, deux nouvelles techniques d'extraction automatique des horizons sismiques sont proposées...
