    Abstract: A process for the enhanced recovery of oil in a deposit introduces into the deposit an alkaline aqueous solution of a water-soluble polymer containing a surfactant. The aqueous solution of water-soluble polymer introduced is prepared with an aqueous solution initially containing Ca2+ and Mg2+ ions treated with an alkaline agent and a dispersant, so as, prior to the introduction of the polymer and the surfactant into the aqueous solution, to precipitate, under the action of the alkaline agent and of CO2 optionally dissolved in the aqueous solution, the Ca2+ and Mg2+ ions. The precipitates are especially in the form of precipitates of calcium carbonate and of magnesium hydroxide and are dispersed owing to the dispersant, which is chosen in order to limit the size of the calcium carbonate and magnesium hydroxide precipitates.
