Abstract: A process for producing petroleum from a subterranean reservoir is provided whereby a solvent equal in density or more dense than water is circulated between upper and lower perforations in a first well in order to dissolve petroleum in an ever-widening volume around the well bore until communication is established to a second well. At this point the production side of the first well is shut in, injection of solvent is ceased, an aqueous fluid is injected into the first well and production is taken from the second well.

Abstract: A method of recovering hydrocarbons from a subterranean hydrocarbon-bearing formation wherein a mixture of steam and a minor amount of an interfacial tension reducer, such as quinoline, etc. is introduced into the formation and oil displaced through the formation is recovered through a production well. Preferably, the formation is heated prior to the introduction of the steam-interfacial tension reducer mixture.
