This study begins with a bibliographicrevision to set up the constraints and the assumptions for the different chemical models. Numerical modeling isused to evaluate the efficiency of the applied injection processes. As most of the parameters are in general poorlyknown at reservoir scale, several hypotheses is tested in order to analyze their impacts over the final results. Finally,the most viable and profitable method in terms of final recovery is identified after evaluating different chemicalsystems as polymer, surfactant, alkaline-surfactant (AS), surfactant-polymer (SP) and alkaline-surfactant-polymer(ASP). A summary of the geology and the reservoir characteristics is introduced. The main part of this report dealswith simulations of the different chemical treatments. Finally, by the comparison of the evaluated systems, the bestenhanced oil recovery is obtained by an injection of a mobility control agent (Polymer), with a final recovery of 30%OOIP. %G English %2 https://ifp.hal.science/hal-01779611/document %2 https://ifp.hal.science/hal-01779611/file/Report%20ZarateRada_VF.pdf %L hal-01779611 %U https://ifp.hal.science/hal-01779611 %~ IFP %~ LARA
