A method is disclosed for forming a carbon dioxide-containing mixture which is miscible with crude oil. The method comprises maintaining a mixture of crude oil and carbon dioxide in an extraction zone at a temperature and pressure such that multiple phase equilibrium is achieved therebetween. A carbon dioxide-rich phase that includes a mixture of carbon dioxide and hydrocarbons is withdrawn and is miscible with the reservoir crude oil when injected into the reservoir from which the crude oil was produced.
