Surfactant for improved oil recovery (IOR) has been for many years, particularly in the 1970’ and 1980’ when the technology was put on a sound scientific basis. Unfortunately, the economic reality of the process performance in field trials has precluded widespread deployment of this technology. Many surfactants have been evaluated for their ability to recover incremental oil and this study is focus on Polysorbate 20 as candidate for this IOR application. This laboratory study determined the characteristics of Polysorbate 20 surfactant formulations, in particular for their capability to create low interfacial tensions (IFT) with n-alkane hydrocarbons. Formulations explored included a wide range of sorbitan-based surfactants as co-surfactants with this Polysorbate 20 surfactant. Some combination of Polysorbate 20 with co-surfactant did exhibit low interfacial tension (IFT) values of 0.01 dyne/m or less versus n-octane. Laboratory testing did confirm the useful properties that the IFT for these Polysoarbate 20 formulations can be largely independent of both salinity and temperature. Preliminary studies also suggest Polysorbate 20 will have only modest adsorption onto kaolinite clay and crushed sandstone.
