Two Kuwaiti Oil Company firefighters shelter themselves from the intense heat of an oil well fire in a spray of water, behind a piece of metal roofing as they guide a "stinger" on the end of a long boom that will pump drilling mud into the gushing well at high pressure to stop the fire and flow of gas and oil. Rumaila oilfield, southern Iraq. The Rumaila field is one of Iraq's biggest with 5 billion barrels in reserve. Many of the wells are 10,000 feet deep and produce huge volumes of oil and gas under tremendous pressure, which makes capping them very difficult and dangerous. Rumaila is also spelled Rumeilah.
