    Abstract: (Branched alkyl)-polyethoxyalkyl sulfonates, and similar compounds wherein the alkyl sulfonate moiety is replaced by a sulfate moiety, having an aromatic group on one of the branches of the branched alkyl group are provided. These compounds are surfactants which are particularly useful for chemical waterflooding, especially in high brine environments.
