The autonomous regions are concentrated the bulk of the country's oil and gas. The total volume of exploration drilling has exceeded 45 million meters. 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]. Ore minerals and precious stones discovered on the eastern slope of the Subpolar and
Polar Urals (in particular, the deposits of
Lead,
copper,
chromite). The area is rich in fresh water resources, which are represented by large rivers - the Ob, Irtysh, Tobol, lakes (650 ths.) - Black (224 km2), Big Uvat (179 km2), etc., groundwater, that contain more than half of Russian stocks. iodine (30 mlg / l) and bromine (40-50 mlg / l) Over 44% of the land reserves in the south of the region are covered with forests. 43 million hectares are covered by forests. The forest resources area is the third largest in the Russian Federation after the Krasnoyarsk Territory and the Irkutsk Region. The main forest forming species are pine, birch, spruce, fir, aspen and larch. The total timber reserves are estimated at 5.4 billion cubic meters. In the south of the Tyumen region are about ten hot (37-50 °C)
geothermal sources, having
balneological properties. Sources are popular not only among residents of Tyumen, but in neighboring regions as well: the
Sverdlovsk,
Kurgan, and
Chelyabinsk regions. The region has large peat reserves. Large deposits of
vivianite (ferric phosphate) (approximately 20% of world reserves) have been discovered in particular peat deposits, the usage of which may meet the
phosphate fertilizers demand of the agriculture. There are deposits of quartz sands, brick and expanded clays, sapropels and limestone. The region has large fresh and mineral water reserves. There are great prospects for
oil field development. ==Economy==
