This report summarizes results of a basic study of coalescence phenomena, emulsion formation and stability, and dynamic interfacial properties when crude oils are contacted with aqueous solutions of surfactant/polymer and alkaline agents. These measurements are correlated with each other and with oil displacement efficiency by chemical flooding in laboratory experiments. Crude oils from Salem, Loudon, Huntington Beach and Wilmington fields, and two pure hydrocarbons, namely n-octane and n-dodecane, were used in the present study. The six chemical recovery agents employed were Petrostep 420, TRS 10-80, TRS 10-410, orthoxylene sulfonate, sodium hydroxide and sodium orthosilicate. 45 figures, 6 tables.
