Abstract: Overbased branched chain aliphatic sulfonates are prepared by adding an excess of a base component such as an alkali metal hydroxide, ammonium hydroxide, or an alkali metal carbonate to a sulfonate derived by sulfonating a branched chain alkene such as a propylene tetramer and neutralizing the sulfonic acid thus formed with the base component. The overbased sulfonate is injected into a petroliferous formation to improve a water flood operation. In one embodiment overbasing base component is injected as a slug subsequent to injection of the sulfonate.

Abstract: An improved anionic waterflood additive is prepared by sulfonating a crude oil having an API gravity of at least 25 and an aromatic hydrocarbon content of at least 15 percent by weight; neutralizing the sulfonated crude oil with a base component such as an alkali metal hydroxide, ammonium hydroxide, or an alkali metal carbonate; and overbasing the sulfonate by admixing with an excess of base component such that the ratio: ''''weight of excess base component/weight of sulfonate'''' is about 0.03 to about 3.0. The anionic waterflood additive is injected into a petroliferous formation, the formation is waterflooded and oil is recovered.

Abstract: An improved anionic waterflood additive is prepared by chlorinating a normal alkane having about 10 to about 18 carbon atoms to about 15 to about 45 weight percent chlorine content; employing the chlorinated alkane to alkylate an aromatic hydrocarbon such as benzene; sulfonating the thus formed alkylate to form a sulfonic acid; converting the sulfonic acid to a sulfonate by reacting with a base component such as an alkali metal hydroxide, ammonium hydroxide, or an akali metal carbonate; and overbasing the sulfonate by admixing with an excess of base component such that the ratio: ''''weight of excess base component/weight of sulfonate'''' is about 0.03 to about 2.0. The anionic waterflood additive is injected into a petroliferous formation, the formation is waterflooded, and oil is recovered.

Abstract: An overbased anionic waterflood additive comprising a watersoluble low molecular weight alkali metal hydrocarbon sulfonate having an equivalent weight of about 200 to about 400 plus a water-insoluble high molecular weight alkali metal hydrocarbon sulfonate having an equivalent weight of about 400 to about 600 plus an overbasing amount of base component such as an alkali metal hydroxide is prepared and is injected into a petroliferous formation to improve a waterflood process. Sufficient overbasing base component is employed that the ratio ''''weight of excess base component/weight of sulfonate'''' is about 0.03 to about 2.0.
