<p>MICELLAR DISPERSIONS VIA SULFONATING WHOLE OR TOPPED CRUDE Micellar dispersions useful for displacing crude oil from reservoirs are obtained by first producing crude oil from the reservoir (optionally adding sulfonation agents to the crude oil), then sulfonating the mixture with SO3 (optionally diluted in a diluent), thereafter neutralizing mixture with a monovalent base (optionally removing the unreacted oil therefrom) (optionally adding liquid, e.g., cosurfactant to obtain the desired viscosity) and thereafter injecting the resulting micellar dispersion into an injection well and displacing it toward a production well to recover crude oil therethrough.</p> |
