Methods relate to a steam-gas-solvent (SGS) process for recovery of heavy crude oil and bitumen. The methods include injecting a steam-gas-solvent mixture to mobilize hydrocarbons in a formation and producing from the formation the hydrocarbons that are mobilized. The steam-gas-solvent mixture includes steam, a gas non-condensable under reservoir operating conditions and a solvent condensable under reservoir operating conditions.
