ABSTRACT:
Petroleum may be recovered from viscous petroleum containing formations including tar sand deposits by first creating a fluid communication path in the formation, followed by injecting via an injection well a fluid comprising superheated steam and air into the formation via the fluid communication path whereby in situ combustion occurs providing heat and pressure for driving the petroleum in the formation toward the production well. Recovery of the displaced petroleum is accomplished via the production well.
