Nizhnevartovsk in the context of "Western Siberia"

The West Siberian Plain (Russian: Западно-Сибирская равнина, romanized: Zapadno-Sibirskaya ravnina) is a large plain that occupies the western portion of Siberia, between the Ural Mountains in the west and the Yenisei River in the east, and the Altai Mountains on the southeast. Much of the plain is poorly drained and consists of some of the world's largest swamps and floodplains. Important cities include Chelyabinsk, Novosibirsk, Omsk, and Tomsk, as well as Surgut and Nizhnevartovsk.

Winters on the West Siberian Plain are harsh and long. The climate of most of the plain areas is either subarctic or continental. The plain had large petroleum and natural gas reserves. Most of Russia's oil and gas production was extracted from this area during the 1970s and 80s.

Khanty-Mansiysk (Russian: Ха́нты-Манси́йск, romanized: Khánty-Mansíysk, lit. Khanty-Mansi Town; Khanty: Ёмвоҷ, Jomvoćś; Mansi: Абга, Abga) is a city in west-central Russia. Technically, it is situated on the eastern bank of the Irtysh River, 15 kilometers (9.3 mi) from its confluence with the Ob, in the oil-rich region of Western Siberia. Though it is an independent city, Khanty-Mansiysk also functions as the administrative centre of Khanty-Mansiysky District, and the administrative center of Khanty-Mansi Autonomous Okrug–Yugra.

With 101,466 estimated inhabitants, Khanty-Mansiysk is among Russia's few regional capitals that are not the largest cities in their surrounding area, as it is surpassed in population by Surgut, Nizhnevartovsk and Nefteyugansk.
