ABSTRACT:
The invention relates to the creation of a numerical deterministic model of the diffusive type allowing 2D or 3D simulation of the filling of sedimentary basins by siliciclastic and carbonate sediments. A read only memory known data relative to the architecture of a basin and measuring data, well logs, seismic surveys, etc, a set of input data relative to the accomodation created by subsidence and eustasy, the deposit and the production of fluvial or marine sediments, and physical transport parameters such as diffusion coefficients of the various lithologies are created. This set of data is applied to a numerical model. The results that can be deduced therefrom concerning the geometry and the lithologies of the sedimentary units are compared with the measuring data, and the input data are processed stepwise by inversion. The model thus created allows the reconstruction of, for example, the volumetric partitioning, the distortion of the genetic units or the sedimentary geometries observed. The method can be applied for oil reservoir prospecting.
