Heating is essential in in situ production of heavy-oil or bitumen. Steam-based thermal recovery techniques, such as steam assisted gravity drainage (SAGD), cyclic steam stimulation (CSS) and their modifications, are the most common ones. Despite its technical success, it is an energy intensive process due to the cost of steam generation.
