It does, but actually oil well fires have been put out with explosives. During the first USA-Iraq war Saddam Hussein's troops lit up several hundred oil wells as they withdrew from Kuwait. Some of these were extinguished with the help of explosives. The situation is not fully analogous though, since in the case of Sweden it was too dangerous to get even remotely close to the source of fire.
