  • Publication number: 20210301194
    Abstract: The present disclosure provides a method for recovering bitumen that includes contacting 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 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.

  • Publication number: 20210261852
    Abstract: The present disclosure relates to an improved bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in-situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present disclosure involves the step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(CH2CH2O)m(CH2CH(CH3)O)nH wherein R is a linear, branched, cyclic alkyl, phenyl, or alkyl phenyl group of at least 4 carbons, and m and n are independently 1 to 3.
