摘要： The present invention provides a novel method and system for generating steam in the oil and gas industry, in particular, in the heavy oil industry. The process comprises feeding boiler feed water (BFW) of sufficient quality through one or more primary wet steam generators to generate primary wet steam therefrom; separating the primary wet steam into primary dry steam and a primary liquid phase; and feeding the primary liquid phase into one or more secondary steam generators to generate secondary steam therefrom. The secondary steam generators may or may not be wet steam generators. This unique serial configuration results in increased steam production per unit of inlet BFW, as well as an overall reduction of liquid waste or boiler blowdown, when compared to the conventional SAGD wet steam generation configuration. A system for carrying out the process is also provided.
