Abstract

Procédé de localisation et d'identification des anomalies d'un milieu. Il est caractérisé en ce qu'il consiste à: utiliser un bloc sismique donné (1) composé de traces sismiques repérées par leurs coordonnées spatiales; délimiter dans ledit bloc sismique au moins un intervalle temporel entre un niveau supérieur (2) et un niveau inférieur (3); sélectionner un modèle temporel (5) d'une anomalie; corréler ledit modèle (5) avec chacune desdites traces (4) comprises dans ledit intervalle temporel; déterminer, pour chaque trace, la corrélation maximum ( GAMMA M) et le temps (ti) correspondant de ladite corrélation maximum; réaliser une carte (7) des corrélations maximales égale aux dimensions spatiales du bloc sismique (1) et une carte (8) desdits temps correspondant aux maxima de corrélation; ladite carte des temps étant de mêmes dimensions et repérée dans le même système d'axes (x, y) que ladite carte des maxima de corrélation.
