1. A method for recovering hydrocarbons from a hydrocarbon-containing formation, the method comprising:
determining a pressure of the hydrocarbon-containing formation from one or both of field measurements and reservoir characterization;
determining a temperature of the hydrocarbon-containing formation from one or both of field measurements and reservoir characterization;
determining one or more properties of the formation, where the properties are selected from a group consisting of total acid number of the hydrocarbons, total base number of the hydrocarbons, rock type, and brine ionic composition;
determining a desired amount of wettability alteration of the formation;
modeling the formation using a surface complexation model based on the determined pressure, temperature, and one or more properties to output an estimated wellbore fluid composition, wherein the estimated wellbore fluid composition provides the desired amount of wettability alteration of the formation;
preparing an aqueous wellbore fluid based on the estimated wellbore fluid composition; and
injecting the aqueous wellbore fluid into a formation.
