Abstract: A method for generating a digital stochastic model representing the spatial distribution of at least one petrophysical feature consists of the following stages: - setting out the heterogeneous medium in space with the aid of a flexible grid; - generating a regular cartesian grid with a mesh size in a given direction at least as big as the greatest side of the flexible mesh cells in that direction; - simulating, with the aid of a geostatic simulator, at least one form of the petrophysical feature on the cartesian grid from at least one random number; - re-sampling the form on a scale no greater than the smallest cells of the flexible grid; - constructing a geostatistical realisation of an oil deposit model on the flexible grid by attribution of the values of the re-sampled model that are closest to the centre at the centre of the flexible grid cells. The procedure uses a geostatic simulator based on the FFT-MA (Moving Average) method.
