Abstract
A method and a device for determining geological facies in subsoil for oil and gas exploration. The method determines a combined proportion cube from a first meshed proportion cube and a second meshed proportion cube. The invention combines some facies models giving vertical probabilities and some facies models giving horizontal probabilities. This determination is particularly efficient in the presence of a zero probability in one of these models and is capable of respecting the mathematical constraint according to which the sum of each row and each column in the final proportion model must be equal to a predetermined maximum value.
