A method and apparatus extinguishes an oil well or gas well fire burning as a consequence of ignited oil and/or gas escaping the well. The method employs an elevated chimney that is placed over the burning well to cause combustion to shift from the well to an elevated position above the well at the top of the chimney as oil and/or gas continue to escape from the well through the chimney. This provides a route for the passage of unignited oil and/or gas from a lower portion of the chimney. The unignited oil and/or gas can be conducted away from the well while oil and/or gas escaping from the top of the chimney continues to burn. The fire is extinguished by closing off the top of the chimney while permitting all of the oil and/or gas escaping from the well to be routed away from the well in unignited condition through the power portion of the chimney. After the fire is extinguished, the chimney can be removed to permit the well to be closed against further escape of oil and/or gas.
