ABSTRACT:
The optimal salinity of an emulsifier system comprising an alcohol and a neutralized oxidized solvent extracted oil can be controlled to match the salinity of the brine used in the tertiary oil recovery process by controlling the acid number of the solvent extracted oil during the oxidation procedure, controlling the extent of the neutralization during neutralization of the oxidized solvent extracted oil, or both.
