Summary:This invention relates to enhanced oil recovery methods to improve hydrocarbon reservoir production. An enhanced oil recovery screening model has been developed which consists of a set of correlations to estimate the oil recovery from miscible and immiscible gas/solvent injection (CO2, N2, and hydrocarbons), polymer flood, surfactant polymer flood, alkaline-polymer flood and alkaline surfactant- polymer flood. La présente invention concerne des procédés améliorés d'extraction du pétrole ayant pour effet l'augmentation de la production d'un gisement d'hydrocarbures. Un modèle de criblage utilisable en vue de l'amélioration de l'extraction du pétrole a été mis au point. Il consiste en un ensemble de corrélations permettant d'estimer la quantité de pétrole extraite suite à l'injection de gaz/solvant miscible et non miscible (CO2, N2 et hydrocarbures), à l'injection de polymères, à l'injection de polymères tensioactifs, à l'injection de polymères alcalins et à l'injection de polymères tensioactifs alcalins.
