The underlying optimization problem requires dedicated techniques : derivatives are often not available, the associated forward problems are CPU time consuming and some constraints may be introduced to handle a priori information. In this paper, we propose a derivative free optimization method based on trust region approach coupled with local quadratic interpolating models of the cost function and of non linear constraints. Results obtained with this method on a synthetic reservoir application with the joint inversion of production data and 4D seismic data are presented. Its performances are compared with a classical sequential quadratic programming method in terms of numbers of simulation of the forward problem. %G English %2 https://ifp.hal.science/hal-02284341/document %2 https://ifp.hal.science/hal-02284341/file/2010EAGE_Barcelone_HL.pdf %L hal-02284341 %U https://ifp.hal.science/hal-02284341 %~ IFP
