CARBON DIOXIDE FLOODING WITH A PREMIXED TRANSITION ZONE OF CARBON DIOXIDE AND CRUDE OIL COMPONENTS (D#76,439 -F) ABSTRACT The disclosed invention is a method of recovering hydrocarbons by determining the critical concentrations of various crude oil components to carbon dioxide to achieve first contact miscibility of a mixture of said crude oil components and carbon dioxide with the underground hydrocarbons at formation temperature and a selected pressure substantially lower than first contact miscibility pressure of carbon dioxide with the hydrocarbons; injecting into the formation a premixed transition zone slug comprising carbon dioxide and said crude oil components at said critical concentrations, formation temperature and said selected pressure; and injecting a drive fluid into the formation after the premixed transition zone slug.
