Heavy oil may exist as unconsolidated deposits in thin zones, sometimes underlain by bottom water, which deposits flow under solution-gas drive primary recovery mechanisms, resulting in rapid reduction in reservoir pressure and recovery of quantities of sand with oil. A gravity-drainage assisted steam flooding process for recovery from thin viscous reservoirs uses a single horizontal wellbore. Steam is injected through tubing penetrating the reservoir to condition and heat the wellbore producing oil and reservoir fluids. After a period of steam circulation, production is constrained and steam injection is continued to initiate an active steam chamber. Fluid withdrawal is resumed while pressure is maintained. Steam injection is continued to cause the expansion and propagation of the active steam heated volume. As steam flows into the reservoir under gravitational counter current flow and pressure drive, heated oil, steam condensate and reservoir fluids drain and are pumped to the surface.
