## Natural resources

Oil production is concentrated in the Middle Ob. Gas is produced mainly in the northern areas. Large oil fields are located in the Khanty-Ugra: Samotlor Field, Ob, Fyodorovskoye Field, Mamontovskoye, Krasnoleninskoye; gas - in the Yamalo-Nenets District: Urengoy Field, Bear, Yamburg Field. The depth from 700 m to 4 km. Produced peat, sapropel, quartz sand, limestone. Explored about 400 deposits of raw materials for the production of building materials [source not specified 252 days].

The area is rich in fresh water resources, which are represented by large rivers - the Ob, Irtysh, Tobol, lakes (650 ths.) - Black (224 km$^2$), Big Uvat (179 km$^2$), etc., groundwater, that contain more than half of Russian stocks. iodine (30 mlg / l) and bromine (40-50 mlg / l)
