摘要：
The present disclosure includes a nonionic surfactant and a method of providing the nonionic surfactant, where the nonionic surfactant is soluble in carbon dioxide and is used as part of a dispersion for enhanced crude oil recovery. The nonionic surfactant can be part of an emulsion that includes carbon dioxide and a diluent.
