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.

Abstract: Surfactants constructed from three synthetic building blocks that contain multiple hydrocarbon chains, ethyleneamine, and alkyl sulfonate salt groups, were shown to possess good thermal stability, and foamability, and high foam profiles. The materials are targeted for high temperature foaming applications, such as foam flooding enhanced oil recovery to improve conformance control and other oil and gas downhole foaming applications.

Abstract: The present invention relates to an in situ staged steam extraction method for removing petroleum products from a heavy oil or bitumen reservoir from subterranean locations. Specifically, each injection stage comprises a different steam composition. A steam composition may consist essentially of steam or may comprise one or more enhanced oil recovery agent.

Abstract: The present invention 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 invention involves the step of treating oil sands with an ethylene oxide capped glycol ether described by the structure: RO—(CH2CH(CH3)O)m(C2H4O)n, H wherein R is a linear, branched, cyclic alkyl, phenyl, or alkyl phenyl group of greater than 5 carbons and m and n are independently 1 to 3.
