ABSTRACT:
A method for simulating flows in reservoirs, such as hydrocarbons, by means of chimera type grid which fluid generates a chimera grid made up of a set of elementary grids for accounting for characteristics of the flows and of the geometry (e.g., radial grid in the well zone and CPG grid for the reservoir) so that their union covers the entire simulation domain and that there is a minimum overlap between two neighboring elementary grids. Interpolation parameters allowing connection of the flows calculated on the grid to the flows calculated on the neighboring grids are then determined on the border of each elementary grid. Finally, flows are simulated within the reservoir and the well, and the variables describing the flow on the border of the overlap zones are interpolated using the interpolation parameters.
