This report presents results of a basic study of coalescence phenomena, emulsion formation and stability, and dynamic interfacial properties when crude oils and pure hydrocarbons are contacted with aqueous solutions of surfactant/polymer and alkaline agents. These measurements are correlated with each other and with observations on oil bank formation and displacement and recovery efficiency by chemical flooding in microwave monitored laboratory core flooding experiments. The scope of this work includes three interrelated tasks: I - Caustic Flooding of Heavy Crude, II - Surfactant/Polymer Flooding, and III - Thin Liquid Films: drainage and stability of foam and emulsion films. Results obtained in each of these three tasks are summarized: Crude oils from Huntington Beach, Wilmington Field, Salem and El Dorado and the hydrocarbon, decane were used. The chemical agents employed were: n-hexanol, Dow Pusher 700, sodium lauryl sulfate, lauryl alcohol, petroleum sulfonate, TRS 10-80, TRS 10-410, iBuOH, NaCl brine, sodium orthosilicate, sodium hydroxide, Petrostep 465, and C/sub 3/ to C/sub 5/ alcohols.
