Bruist, E H

In a method of recovering oil from a steeply dipping reservoir, a downdip opening into the interval is provided by completing at least one well so that one path of fluid communication extends through the thickness of the interval along a horizontal line substantially normal to the bedding planes. An updip opening is then provided into the same interval by completing at least one well at a depth above that of the downdip opening into the interval substantially normal to the bedding planes. Communication between the 2 wells is provided by a layer or fracture within the interval more or less parallel to the bedding planes. The hydrocarbons within or near the permeable layer are heated. A combustion-supporting fluid is injected through the updip opening into the interval so as to initiate a reverse combustion of the heated hydrocarbons within the permeable layer or adjacent to the fracture.
