A STEAM-GAS-SOLVENT (SGS) PROCESS FOR RECOVERY OF HEAVY CRUDE OIL AND BITUMEN

摘要

Methods relate to a steam-gas-solvent (SGS) process for recovery of heavycrudeoil and bitumen. The methods include injecting a steam-gas-solvent mixture tomobilizehydrocarbons in a formation and producing from the formation the hydrocarbonsthat aremobilized. The steam-gas-solvent mixture includes steam, a gas non-condensableunderreservoir operating conditions and a solvent condensable under reservoiroperatingconditions.
