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 a glycol ether amine described by the following structure: R—(OC2H4)x—NH2 or R—(OCH2CH(CH3))y— NH2 wherein R is a C1 to C6 alkyl group or a phenyl group and x and y independently are 1 to 3.

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: 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. A bitumen recovery process may be used to extract bitumen from oil sands. Specifically, the bitumen recover process involves a step of treating oil sands with a propylene oxide capped glycol ether described by the structure: RO—(C2H4O)n—CH2CH(CH3)OH wherein R is a linear, branched, or cyclic alkyl, phenyl, alkyl phenyl group and n is 1 to 10.
