  • HYDROCARBON RECOVERY WITH STEAM AND SOLVENT STAGES
    Publication number: 20220315828
    Abstract: A steam-assisted gravity drainage method is described that includes a two stage solvent injection scheme, wherein steam plus solvent injection is followed by steam plus heavier-solvent injection. The two solvent injections improve recoveries of both the heavy oil and the injected solvent while limiting steam requirements, thus improving the economics of the method.
    Type: Application
