The application of steam-assisted gravity drainage to produce superviscous oil requires the preparation and utilization of a large amount of water. The use of waterwith impurities of superviscous oil for holding the formation pressure at deposits developed by traditional methods has technological and economical limitationssince the need in injection is absent, while its pumping-over to remote territories is very costly. In order to decrease the effect on the surrounding mediumand economize considerably volumes of sweet water of terrestrial water sources with impurities of superviscous oil after the corresponding purification and preparation,it is proposed to use it repeatedly for steam production. Purification problems of water with a high content of hydrogen sulfide and superviscous oil productsfor its further use in a boiler house are considered. The results of pilot tests for verification of technological solutions on removal oil products, hydrogen sulfide,hardness, and alkalinity are shown.
