Pilot operation of the field was started in 2005 and on 15 October 2008, first oil produced at the Verkhnechonskoye field was delivered. As of 2007, total proved reserves of Verkhnechonskoye were 409 million barrels (65.0×106 m3) of oil equivalent, and proved, possible and probable (3P) reserves amounted to 1.886 billion barrels (299.9×106 m3). Natural gas reserves are 95.5 billion cubic meters. In 2009, the field produced through 41 oil wells 1.181 million tons of oil, equal to 23,500 barrels per day (3,740 m3/d). The field is operated by Verkhnechonskneftegaz, a joint venture of TNK-BP (68.51%), Rosneft (25.94%), and East Siberian Gas Co. (5.48%).
