  • Modified nonionic surfactant formulations for enhanced oil recovery
    Patent number: 10414971
    Abstract: Embodiments of the present disclosure include modified nonionic surfactant formulations having a nonionic surfactant and a pour point depressant, where the modified nonionic surfactant formulations have a pour point of ?54° C. to ?75° C. In one or more embodiments, the modified nonionic surfactant formulations can be introduced into a flow of carbon dioxide, where the flow of carbon dioxide and the modified nonionic surfactant formulation are injected into an oil containing reservoir. In one or more embodiments, an emulsion of the carbon dioxide and the nonionic surfactant form in the oil containing reservoir, where the use of the pour point depressant provides minimal interference in forming the emulsion.
