The method and apparatus of this invention provides a cannon-like device for projecting a sheath of fire extinguishing particles rapidly upwardly along a flaming oil and/or gas stream gushing up from an oil and/or gas well. The sheath instantaneously insulates the oil and/or gas in the stream from the surrounding atmosphere to freeze the flame at the tip of the sheath and shield the stream within the sheath from contact with the flaming oil and/or gas above and around the stream of oil and/or gas enclosed within the sheath until all of the already flaming oil and/or gas has been burned out. The method for eliminating the flames above the outlet of an oil well is accomplished by separating the oil and/or gas stream flowing from the oil and/or gas well from the flames by producing a sheath of fire extinguishing material, driven by an explosive charge into a position to surround and separate the oil and/or gas stream from the flames.
