During the Soviet period, the high authority in the oblast was shared between three persons: The first secretary of the Tyumen CPSU Committee (who in reality had the biggest authority), the chairman of the oblast Soviet (legislative power), and the Chairman of the oblast Executive Committee (executive power). Since 1991, CPSU lost all the power, and the head of the Oblast administration, and eventually the governor was appointed/elected alongside elected regional parliament.
The politics in the oblast is governed by the Charter of Tyumen Oblast. The laws within the authority of the oblast are passed by the Legislative Assembly of Tymen Oblast which is the legislative (representative) body. The highest executive body is the Tyumen Oblast Administration. It also includes the executive bodies of the subdivisions such as districts, and is responsible for the daily administration. The Oblast administration supports the activities of the Governor who is the head of the oblast and acts as guarantor of the observance of the Charter in accordance with the Constitution of Russia.
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, Ob, Fyodorovskoye, Mamontovskoye, Krasnoleninskoye; gas - in the Yamalo-Nenets District: Urengoi, Bear, Yamburg. 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 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.

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 fields development.
Tyumen is a service center for gas and oil industries: the Oblast has the highest level of oil and gas production of any region in Russia. Gazprom, LUKoil and Gazpromneft, TNK-BP, Shell, Salym Petroleum Development N.V. have representative offices in Tyumen. It has been suggested that the importance of these industries has caused the high levels of economic inequality observed in the region.
