  • Method of gas-cap air injection for thermal oil recovery
    Patent number: 8176980
    Abstract: A method for producing bitumen or heavy oil from a subsurface oil sands reservoir, the subsurface oil sands reservoir and an overlying gas zone in fluid communication, the method includes providing an in situ combustion process in the overlying gas zone, to create or expand a combustion front within the overlying gas zone, providing a thermal recovery process in the oil sands reservoir, to create or expand a rising hot zone within the oil sands reservoir, and selectively operating the thermal recovery process or the in situ combustion process or both such that the rising hot zone does not intersect the overlying gas zone until the combustion front has moved beyond that portion of the overlying gas zone at the intersection.
