Abstract
The invention is a method applicable to a geologic structure, such as an oil bearing reservoir, defined from available data acquired either through measurements or through analyses and interpretations of seismic data or loggings performed in wells. The invention comprises previous modeling of the boundaries (zone edges, discontinuities or faults for example) by of triangulated surfaces enveloping as far as possible these boundaries and splitting up of the zone studied into blocks having at most six faces, whose faces correspond to discontinuities or main faults of the zone previously triangulated. Each block is thereafter subdivided into a set of elementary cells necessary for modeling the zone by finite elements or differences, by performing a gridding of each of the faces of the block by interpolation from the edges thereof so as to obtain a grid, followed by populating each block with nodes in the thickness thereof, by interpolation from the nodes of the various grids formed on the various faces, these operations being accompanied by particular homogenization procedures in order to readjust the size of the cells within each block according to predetermined rules. The gridded blocks are thereafter reassembled.
