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.

Additive for enhanced oil recovery

Embodiments of the present disclosure are directed towards methods of enhanced oil recovery from a subterranean reservoir, the method includes co-injecting a gas and a foam formulation into the subterranean reservoir, wherein the gas comprises steam and the foam formulation comprises a sulfonate composition, a glycol compound, and water.

Enhanced oil recovery methods and compositions

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&#xb0; 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.

Additives for enhanced extraction of bitumen

Embodiments 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.

Alkanolamine and glycol ether composition for enhanced extraction of bitumen

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.

Foam-forming composition for steam assisted oil recovery

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.

Composition for steam extraction of bitumen

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&#x2014;(CHCH(CH)O)(CHO)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.

Enhanced steam extraction of bitumen from oil sands

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.
