A method is described for enhancing the rate of oil production from an oil-bearing reservoir within a dipping subterranean formation, comprising the steps of: (a) penetrating the dipping formation with production wells, (b) injecting steam into the dipping formation above the upper-most one of the production wells to heat the oilbearing reservoir within the formation, and (c) co-injecting steam into the dipping formation below the lower-most one of the production wells, the injection of steam above the upper-most production well exhibiting a gas cap effect on the oil-bearing reservoir and the injection of steam below the lower-most production well exhibiting a fluid drive with an override effect on the oilbearing reservoir, thereby increasing the growth rate of steam surrounding the reservoir and accelerating the rate of heat communication to the reservoir.
