Zusammenfassung:	STEAM ENHANCED OIL RECOVERY METHOD USING BRANCHED ALKYL AROMATIC SULFONATES A method of enhanced oil recovery using foam to improve the effectiveness of steam to mobilize viscous crude, either for steam stimulation in a single well or for steam drive between wells. A new surfactant composition having branched alkyl aromatic sulfonates as the effective agent for the steam foamer is used because of its ability to foam in the presence of substantial pore volumes of residual oil and thereby mobilize significant amounts of producible oil by diverting steam to less-permeable zones.
