Extraction of heavy oil often involves the production of steam for injection into the formation (steam flooding, cyclic steam, SAGD). In order to minimize or eliminate the consumption of fresh water to feed steam generators, produced water (the water which comes to the surface along with the oil) is often treated and conditioned to a quality suitable for feed to a steam generator.
Once-through-steam-generators (OTSG) can generally be fed produced water which has been filtered and softened. In some cases, initial treatment for silica is also employed.
