Abstract
Ether amine additives are used in oil recovery such as steam-assisted gravity drainage and cyclic steam stimulation, as well as surface mining of bitumen. Methods of oil recovery using the ether amine additives are described. The ether amine additives are injected with steam into a subterranean oil reservoir such as oil tar sands to improve recovery of oils such as bitumen and/or heavy oil, or used to wash surface-mined rock to assist in oil extraction therefrom. The ether amine additives may be added to steam in steam-assisted oil recovery methods such as cyclic steam stimulation and steam-assisted gravity drainage. Condensates of the additives in steam exhibit very low advancing and receding contact angles and low interfacial tensions at low concentrations of the additives.
