摘要： A method of enhanced oil recovery that includes injecting a composition including an hyperbranched polyglycerol into an injection well in a subterranean oil-bearing reservoir, the hyperbranched polyglycerol being a primary alcohol that is a reaction product of a C2 to C25 carbon alcohol and a plurality of glycidols; and displacing oil in the subterranean oil-bearing reservoir using the composition.

摘要： The present invention relates to a 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 composition comprising an alkanolamine and an ethylene oxide capped glycol ether and/or propylene oxide capped glycol ether.

摘要： 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.

摘要： The present invention includes a foam-forming composition for use in enhanced heavy oil recovery, and a method of using said foam-forming composition for recovering heavy oil and/or bitumen. The foam-forming composition of the present invention comprises a mixture of (di)alkyl diphenyloxide (di)sulfonate compounds and the process of heavy oil recovery is performed at elevated temperatures using steam.

摘要： 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.
