Abstract: A method of producing hydrocarbons from a well. The method begins by injecting steam into a well. The bitumen in the formation is then heated with the injected steam, followed by ceasing the injection of steam into the well and then by soaking the bitumen with the injected steam and collecting the heated oil. Steam that has condensed is revaporized by directing RF/MW radiation to the steam allowing for more bitumen to be produced without injecting more steam. In addition, some of the steam could become superheated, wherein the temperature of the superheated steam is greater than the temperature of the steam. The bitumen is heated by the revaporized steam and the superheated steam, followed by soaking the bitumen with the revaporized steam and the superheated steam. Hydrocarbons are then produced from the well.
