Weapons labs in the former Soviet Union developed special nukes for use to help pinch off the gas wells. They believed that the force from a nuclear explosion could squeeze shut any hole within 82 to 164 feet (25 to 50 meters), depending on the explosion’s power. That required drilling holes to place the nuclear device close to the target wells.
A first test in the fall of 1966 proved successful in sealing up an underground gas well in southern Uzbekistan, and so the Russians used nukes four more times for capping runaway wells.
