On 6 February 2020, Gazprom Neft-Vostok announced discovery of a new pool at the Urmanskoye field in Tomsk Oblast (Western Siberia). New-pool wildcat Urmanskaya 26 was drilled to 3,660 m in the south-eastern extension of the field in the Archinskiy license. The well tested oil at a rate of 670 b/d from carbonate reservoirs of the Paleozoic basement. The company estimated 3P oil reserves of the pool at 37 MMbbl in-place and 11 MMbbl of recoverable. In 2020, the operator plans to drill four horizontal development wells aiming at speedy development of the new discovery.  Urmanskoye, discovered in 1974, is located in the Kaymys-Vasyugan Province. Fourteen pools, mostly linked to stratigraphic traps, are distributed within the 400 m Paleozoic-Lower Jurassic section. Five oil accumulations including the new discovery are localized in the upper portion of a basement (weathering crust) in fractured reservoirs. Initial 2P reserves of the field are estimated at 295 MMbbl of oil. Commercial oil production was started in 2005 and the output reached 9,600 b/d in 2009. Since then, production has been declining.
