ABSTRACT A method for steam stimulating a heavy oil reservoir which realizes significant energy savings is disclosed. Steam is injected into the reser- voir via one well, permitted to soak and then produced back directly into the reservoir via a second well. This flowback steam production is termi- nated when wellhead pressures equalize, or when more than trace amounts of hydrocarbons are produced. Additional steam is injected into the reservoir via the second well, permitted to soak, and heated heavy oil is produced via both wells.
