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.
