The waters of oil fields are characterized by low concentrations of iodine. It is required to create new technologies for the extraction of iodine from groundwater, which will reduce the iodine deficiency in Russia. It is necessary to organize the production of iodine from oil waters, in order not to depend on imports. The construction of new factories producing iodine is extremely timeconsuming and costly. Therefore, the issue of the integrated use of produced water requires an immediate solution not only in Western Siberia, but throughout the country. This requires work on new technologies to maximize the use and application of groundwater in order to get that done. The availability of cheap iodine in unlimited quantities can influence new nanotechnologies, contribute to the creation of points of growth for various industries (lasers, computers, etc.).
