Firefighters from the KWWK (Kuwait Wild Well Killers) attempt to kill an oil fire in the Rumaila field by guiding a "stinger" that will pump drilling mud into the damaged well. A "stinger" is a tapered pipe on the end of a long steel boom controlled by a bulldozer. Drilling mud, under high pressure, is pumped through the stinger into the well, stopping the flow of oil and gas. The Rumaila field is one of Iraq's biggest oil fields with five billion barrels in reserve. Rumaila is also spelled Rumeilah.
