<p>Method of assisted recovery of hydrocarbons in a reservoir rock, comprises: preparing an aqueous solution comprising at least one associative polymer and surfactant; determining, by testing, particularly in porous media, the nature, characteristics and the respective concentrations of the surfactant and polymer; inhibiting the polymer hydrophobic links by molecules of surfactant at the vicinity of the surrounding of injection well in the reservoir rock, by flowing in depth in the reservoir rock, strengthening the hydrophobic links; and increasing a value of viscosity of the solution. Method of assisted recovery of hydrocarbons in a reservoir rock, comprises: preparing an aqueous solution comprising at least one associative polymer and surfactant; determining, by testing, particularly in porous media, the nature, characteristics and the respective concentrations of the surfactant and polymer; inhibiting the polymer hydrophobic links by molecules of surfactant to obtain a good injectivity of the solution at the vicinity of the surrounding of injection well in the reservoir rock, by flowing in depth in the reservoir rock, strengthening the hydrophobic links by the adsorption of molecules of the surfactant; and increasing a value of viscosity of the solution.</p> |
