Abstract
A method of developing a petroleum reservoir from a flow model constrained by production data and seismic data is disclosed. It is used to define a development scheme and to start or continue the reservoir development. Production data and seismic data associated with a fine grid are acquired during the development of the reservoir. Production data, as well as pressure and saturation values, are simulated in each cell of the flow model. A pressure value and a saturation value are assigned to each cell of the fine grid. A pressure equation is therefore solved locally on the fine grid and the saturations are calculated by writing the continuity of the phase flows between neighboring lithofacies, the conservation of the pore volume and the conservation of the phase volume. The maps obtained are then used to simulate seismic data.
