The Kumzhinskoye gas field is a condensate gas field in the Nenets Autonomous Okrug of Russia. It lies within the Nenets Nature Reserve, in the Pechora River delta. A fire in an exploratory well, in November 1980, led to the use of a peaceful nuclear explosion in 1981 as an attempt to control the fire. Despite this, hydrocarbon escape occurred after the 37kt explosion, needing further relief well drilling.
As of the mid-2010s, the licence to the gas field is held by CH Invest Company. The size of the field is 225km<sup>2</sup>, and is estimated to annually produce 3.2 billion cubic metres of natural gas and 170,000 tonnes a year of gas condensate.
