Kuwait Oil Fires

The Kuwaiti oil fires were caused by the Iraqi military setting fire to a reported 605 to 732 oil wells along with an unspecified number of oil filled low-lying areas, such as oil lakes and fire trenches, as part of a scorched earth policy while retreating from Kuwait in 1991 due to the advances of US-led coalition forces in the Gulf War. The fires were started in January and February 1991, and the first oil well fires were extinguished in early April 1991, with the last well capped on November 6, 1991.

Motives

The dispute between Iraq and Kuwait over alleged slant-drilling in the Rumaila oil field was one of the reasons for Iraq's invasion of Kuwait in 1990.Thomas C. Hayes

In addition, Kuwait had been producing oil above treaty limits established by OPEC. By the eve of the Iraqi invasion, Kuwait had set production quotas to almost , which coincided with a sharp drop in the price of oil. By the summer of 1990, Kuwaiti overproduction had become a serious point of contention with Iraq.

Some analysts have speculated that one of Saddam Hussein's main motivations in invading Kuwait was to punish the ruling al-Sabah family in Kuwait for not stopping its policy of overproduction, as well as his reasoning behind the destruction of said wells.

It is also hypothesized that Iraq decided to destroy the oil fields to achieve a military advantage, believing the intense smoke plumes serving as smoke screens created by the burning oil wells would inhibit Coalition offensive air strikes, foil allied precision guided weapons and spy satellites, and could screen Iraq's military movements. Furthermore, it is thought that Iraq's military leaders may have regarded the heat, smoke, and debris from hundreds of burning oil wells as presenting a formidable area denial obstacle to Coalition forces. The onset of the oil well destruction supports this military dimension to the sabotage of the wells; for example, during the early stage of the Coalition air campaign, the number of oil wells afire was relatively small but the number increased dramatically in late February with the arrival of the ground war.

The Iraqi military combat engineers also released oil into low-lying areas for defensive purposes against infantry and mechanized units along Kuwait's southern border, by constructing several "fire trenches" roughly 1 kilometer long, 3 meters wide, and 3 meters deep to impede the advance of Coalition ground forces.

The military use of the land based fires should also be seen in context with the coinciding, deliberate, sea based Gulf War oil spill, the apparent strategic goal of which was to foil a potential amphibious landing by U.S. Marines.

Extent

As an international coalition under United States command assembled in anticipation of an invasion of Iraqi-occupied Kuwait, the Iraqi regime decided to destroy as much of Kuwait's oil reserves and infrastructure as possible before withdrawing from that country. As early as December 1990, Iraqi forces placed explosive charges on Kuwaiti oil wells. The wells were systematically sabotaged beginning on January 16, 1991, when the allies commenced air strikes against Iraqi targets. On February 8, satellite images detected the first smoke from burning oil wells. The number of oil fires peaked between February 22 and 24, when the allied ground offensive began.United States Department of Defense ''Environmental Exposure Report: Oil Well Fires'' (updated August 2, 2000)

According to the U.S. Environmental Protection Agency's report to Congress, "the retreating Iraqi army set fire to or damaged over 700 oil wells, storage tanks, refineries, and facilities in Kuwait."United States Environmental Protection Agency (1991)
"Report to Congress: United States Gulf Environmental Technical Assistance"
pp. 14, A-1. Estimates placed the number of oil well fires from 605 to 732. A further thirty-four wells had been destroyed by heavy coalition bombing in January. The Kuwait Petroleum Company's estimate as of September 1991 was that there had been 610 fires, out of a total of 749 facilities damaged or on fire along with an unspecified number of oil filled low-lying areas, such as "oil lakes" and "fire trenches". These fires constituted approximately 50% of the total number of oil well fires in the history of the petroleum industry, and temporarily damaged or destroyed approximately 85% of the wells in every major Kuwaiti oil field.

Concerted efforts to bring the fires and other damage under control began in April 1991. During the uncontrolled burning phase from February to April, various sources estimated that the ignited wellheads burnt through between four and six million barrels of crude oil, and between seventy and one hundred million cubic meters of natural gas per day. Seven months later, 441 facilities had been brought under control, while 308 remained uncontrolled. The last well was capped on November 6, 1991. The total amount of oil burned is generally estimated at one billion barrels or just below one percent of Kuwait's entire supply of 104 billion barrels. Daily global oil consumption in 2015 is about 91.4 million barrels; the oil lost to combustion would last 11 days at modern usage rates.

Financial losses

In March 1991 the accumulated financial losses were estimated to be as much as 10% of 90 billion barrels of Kuwait oil reserves based on a statement made by an Kuwait Oil Company official. At the world prices at the time it would amount $157.5 billion USD.

Military effects

On March 21, 1991, a Royal Saudi Air Force C-130H crashed in heavy smoke due to the Kuwaiti oil fires on approach to Ras Mishab Airport, Saudi Arabia. 92 Senegalese soldiers and 6 Saudi crew members were killed, the largest accident among Coalition forces.Schmitt, Eric (March 22, 1991)

The smoke screening was also used by Iraqi anti-armor forces to a successful extent in the Battle of Phase Line Bullet, having aided in achieving the element of surprise against advancing Bradley (IFV)s, along with increasing the general fog of war.

The fires burned out of control because of the dangers of sending in firefighting crews during the war. Land mines had been placed in areas around the oil wells and military demining was necessary before the fires could be put out. Around of oil were lost each day. Eventually, privately contracted crews extinguished the fires, at a total cost of US$1.5 billion to Kuwait. By that time, however, the fires had burned for approximately ten months, causing widespread pollution.

The fires have been linked with what was later deemed Gulf War syndrome, a chronic disorder afflicting military veterans and civilian workers that include fatigue, muscle pain, and cognitive problems; however, studies have indicated that the firemen who capped the wells did not report any of the symptoms that the soldiers experienced. The causes of Gulf War syndrome have yet to be determined.

From the perspective of ground forces, apart from the occasional "oil rain" experienced by troops very close to spewing wells, one of the more commonly experienced effects of the oil field fires were the ensuing smoke plumes which rose into the atmosphere and then precipitated or fell out of the air via dry deposition and by rain. The pillar-like plumes frequently broadened and joined up with other smoke plumes at higher altitudes, producing a cloudy grey overcast effect, as only about 10% of all the fires corresponding with those that originated from "oil lakes" produced pure black soot filled plumes, 25% of the fires emitted white to grey plumes, while the remainder emitted plumes with colors between grey and black. For example, one Gulf War veteran stated:

A paper published in 2000 analyzed the degree of exposure by troops to particulate matter, including soot. However, the paper focused more-so on silica sand, which can produce silicosis. The paper included troop medical records, and in its conclusion: "A literature review indicated negligible to nonexistent health risk from other inhaled particulate material (other than silica) during the Gulf War".

Extinguishing efforts

The burning wells needed to be extinguished as, without active efforts, Kuwait would lose billions of dollars in oil revenues. It was predicted by experts that the fires would burn for between two and five years before losing pressure and going out on their own.Betchel corporation ''Kuwait: Bringing Back the Sun''
