The disclosed invention is a method of injecting steam foaming agents in conjunction with steam and usually, a non-condensable gas into production wells producing a substantially high water to oil ratio. The most preferred production wells for foaming agent injection are corner production wells of flooding patterns such as inverted 5- and 9-spots, especially when the flooding pattern contains infill wells between the central injection well and the corner production wells.

Although the method of injecting foaming agent, steam and usually, a non-condensable gas is effective with any foaming agent, the method works particularly well with foaming agents of the general formula:
