摘要： A process for the recovery of hydrocarbon such as bitumen/EHO from a hydrocarbon bearing formation in which are situated an upper injection well and a lower production well, the method comprising the steps: preheating an area around and between the wells by circulating hot solvent through the completed interval of each of the wells until sufficient hydraulic communication between both wells is achieved; injecting one or more hydrocarbon solvents into the upper injection well at or above critical temperature of the solvent or solvent mixture, thereby causing a mixture of hydrocarbon and solvent to flow by gravity drainage to the lower production well; and producing the hydrocarbon to the surface through the lower production well. A non-condensable gas may be injected into the solvent chamber created by the hydrocarbon solvent.

摘要： A new class of surfactants exhibits properties, which make the surfactants suitable for use in surfactant flooding for enhanced oil recovery. The surfactants have the formulaXA.sub.r ORSO.sub.3.sup.- M.sup.+ (I)where R is a hydrocarbon or hydroxyl-substituted hydrocarbon group with 2-6 carbon atoms; A is an oxyalkylene group having 2-4 carbon atoms; r is a number from 0-10, preferably 0-5 and most preferably 1-4; X is an hydroxyl group or hydroxyl and ether group containing hydrophobic group, which comprises 2-6, preferably 2-4 end groups containing 3-22 carbon atoms; and M is a cation, preferably a monovalent cation; or a C.sub.1-4 -alkyl ether thereof. A method for the manufacture of the surfactants are also enclosed.
