SECURE has access to a wide variety of anionic and nonionic surfactants to reduce the residual oil saturation when required.  Surfactant selection is  tailored to each project to ensure the residual oil saturation reduction is achieved without any reservoir or surface facility risks while achieving the highest NPV possible. Surfactant studies are not limited to IFT reduction, but also includes compatibility with reservoir conditions, adsorption, phase behavior, compatibility with polymers and porous media studies (sand packs and cores).

Both anionic and nonionic surfactants are available to reduce the residual oil saturation
