Abstract
A method for recovering hydrocarbons from a hydrocarbon-containing formation. The method may include determining the hydrocarbon-containing formation pressure, temperature, and other properties such as the total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include determining a desired amount of wettability alteration of the formation and modeling the formation. Modeling the formation may be based on the determined pressure, temperature, total acid number and total base number of the hydrocarbons, rock type, and brine ionic composition. The method may also include preparing an aqueous wellbore fluid based on the estimated wellbore fluid composition and injecting the aqueous wellbore fluid into the hydrocarbon-containing formation.
