SOLVENT ADDITION TO IMPROVE EFFICIENCY OF HYDROCARBON PRODUCTION

Solvent is co-injected with steam during the start-up phase of a steam assisted gravity drainage ("SAGD") operation. As well solvent is co-injected with steam during the production phase of a SAGD operation. Both processes improve efficiencies for recovering bitumen from oil sands. Cette i...

Summary:Solvent is co-injected with steam during the start-up phase of a steam assisted gravity drainage ("SAGD") operation. As well solvent is co-injected with steam during the production phase of a SAGD operation. Both processes improve efficiencies for recovering bitumen from oil sands. Cette invention concerne un procédé consistant à co-injecter du solvant et de la vapeur d'eau pendant la phase d'initiation d'une opération de drainage par gravité au moyen de vapeur (DGMV). L'invention concerne en outre un procédé consistant à co-injecter du solvant avec de la vapeur d'eau pendant la phase de production d'une opération de DGMV. Les deux procédés permettent d'améliorer l'efficacité de la récupération de bitume à partir de sables bitumineux.
