  • Patent number: 11834607
    Abstract: A method for recovering bitumen that includes contacting the bitumen with steam and/or water and an organic amine having a boiling point at one atmosphere of greater than 145° C. and recovering the bitumen. The bitumen can be in oil sands, where the step of contacting includes contacting the oil sands having bitumen with the steam and/or water and the organic amine. Contacting the bitumen with the steam and/or water and the organic amine and recovering the bitumen can be done in-situ in a subterranean formation.
