INTRODUCTION It is generally accepted that a surfactant system for enhanced tertiary oil recovery must create low hydrocarbon-water interfacial tension@ be compatible with reservoir brine@ exhibit low adsorbtion of surfactant onto formation rock@ and be economical.1 Although considerable differences are foreseen in the application of surfactants to the recovery of gasoline spilled to ground water@ these criteria are applicable@ and@ the necessity to satisfy health@ safety@ and environmental standards must be included. In this report the results of a solicitation of manufacturers of commercially available surfactants for technical literature and samples are presented in tabular form. The tables present physical@ chemical@ and biological characterizations of the samples received that may be useful in selecting a surfactant for this application. Also presented is a statement or comment about each surfactant indicating a typical application and a list of prices obtained during the period of this study. A brief discussion of the similarities and dissimilarities between applying surfactant to the recovery of spilled gasoline and to secondary oil recovery is presented. Some of these correspondences prove advantageous to our application; others do not. The intent of this discussion is to identify those aspects of secondary oil technology which can be applied to the design of a system for enhanced recovery of spilled gasoline. Thirdly@ a basis for selection of commercially available surfactants for effectiveness screening will be proposed. Additional needed characterization@ not available from manufacturers@ will be discussed@ and samples of surfactants held by TRI will be discussed in this light.
