An automatic seismic pattern recognition method is characterised in that it includes determining a given number of seismic patterns to be recognised; providing a set of seismic trace portions for said region; defining a patter n recognition parameter common to all the trace portions, and determining the value of said parameter for each of the trace portions of the set; selecting trace portions among said set; selecting a one-dimensional neural network containing as many cells as there are patterns to be recognised, each cell being assigned a value of the recognition parameter; submitting the neural network to a learning process with the selected trace portions, so that at t he end of said process, each cell matches a pattern to be recognised, and that said patterns are progressively ordered; presenting each trace portion of sa id set to be processed to the classified and ordered neural network; and attributing to each trace portion presented to the network the number of the cell closest to it. The invention is particularly useful for recognising seismic patterns between two horizons defined by plotting a seismic section.
