ABSTRACT:
A process for producing bitumen employing a borehole that has been drilled into a subterranean hydrocarbon-bearing reservoir having a hydrocarbon. A void space is created at the bottom of the borehole. A bundle of spring-loaded guide tubes is inserted through the borehole and into the void space. Each guide tube is enclosed with a smaller diameter flexible tube that is connected to a source of an emulsifying composition comprising an aqueous phase and an emulsifying agent. The emulsifying agent comprises first and a second ethoxylated alkylphenol compounds wherein at least 1% by weight include more than 100 ethoxy groups. The emulsifying composition is released through the flexible tubes to form an oil-in-aqueous phase emulsion in the reservoir. The oil-in-aqueous emulsion is removed from the reservoir.
