Method of constraining by dynamic production data a fine model representative of the distribution in the reservoir of a physical quantity characteristic of the subsoil structure

摘要

Method intended for direct updating, by dynamic production data, of a fine geologic model representative of the distribution, in a reservoir, of a physical quantity characteristic of the subsoil structure. ;The method is based on the coupling of inversion and upscaling techniques allowing to optimize petrophysical parameters of a rougher simulation model resulting from the fine geologic model. It comprises direct parameterization of the fine geologic model, upscaling being only a means of obtaining rapidly an approximation of the simulation results and of their derivatives in relation to the parameterization of the fine geologic model. ;Applications: determination of a development scheme optimizing the production of a hydrocarbon reservoir for example.
