It was the first in Ukraine and probably the only one in the European part of the Soviet Union. Scientists had determined that a large gas condensate field in the area which was discovered in 1970 could hold up to 300 billion cubic meters of fuel. In 1971, 17 wells were already operating in the Krasnograd district. But an accident occurred when drilling a new well at the field in July 1971. Gas came to the surface before the well reached its planned depth and the force of the spewing gas condensate reached 400 atmospheres, throwing two workers into the air.
Engineers took days deciding what to do to stop the well. The nearest village was just 500 meters away. Residents were told to not light any fires and to stay out of their homes and not turn on any lights. Unable to stop the gas, the engineers decided to light it. By the next day, the burning flare was tens of meters high. Several attempts were made during the next year to put out the fire. Filling the well with tons of concrete slabs did not work - they flew apart like toys. Such flares are normally put out by capping the well. But for this case, specialists from Moscow offered an original solution – an underground nuclear explosion."
