Abstract
Methods are disclosed for synthesizing ionic liquid formulations using non-stoichiometric hydrophobic or hydrotropic ionic liquids, including aprotic or protic ionic liquids, to create emulsions, microemulsions, or nanoemulsions. Additionally, the provided ionic liquid formulations may be used to make surfactant-free or detergentless microemulsions or nanoemulsions that may be used as additives for aqueous or oil-based solutions. Methods for introducing an ionic liquid in an injection fluid into a reservoir via an introduction well area also provided. The injection fluid intermingles with reservoir fluid and the intermingled injection fluid and reservoir fluid is retrieved via a production well. Methods for introducing an ionic liquid in an injection fluid may be used for CO2 sequestration within a reservoir. The CO2 may be introduced concurrently or by alternating injections of CO2.
