Matthew Simmons

Saudi Arabian oil reserves In his book, Simmons argues that production from Saudi Arabia and especially from Ghawar—the world's largest oil field—will peak in the near future, if it has not done so already. Simmons bases his case on hundreds of internal documents from Saudi Aramco, professional journals and other authoritative sources. However, by 2016, Saudi production had increased by more than one million barrels per day.

Oil price wager

In August 2005, Simmons bet John Tierney and Rita Simon, the widow of Julian Simon, $2500 each that the price of oil averaged over the entire calendar year of 2010 would be at least $200 per barrel (in 2005 dollars). Simmons would have lost this bet by a very wide margin: 2010 average oil prices did not even reach $100. The world-wide economic collapse created demand destruction that greatly decreased the demand for oil, causing prices to fall.

Appearances and interviews Simmons made contributions to the films Peak Oil – Imposed by Nature, The Power of Community: How Cuba Survived Peak Oil (2006), The End of Suburbia, Crude Impact, and Crude Awakening: The Oil Crash, and appeared on World Energy Television World Energy Video Interview, August 2008

Deepwater Horizon oil spill conjectures Simmons made several controversial comments and predictions regarding the Deepwater Horizon oil spill and BP's solvency, including:

Talking with Bloomberg TV's Mark Crumpton, Lizzie O'Leary and Julie Hyman about BP's oil leak in the Gulf of Mexico, Simmons said, "If it were my family I'd evacuate now, while you still have time". During a June 9, 2010, interview with Fortune, Simmons claimed that BP would "have about a month before they claim Chapter 11". On June 9, 2010, Simmons was interviewed by Barron's journalist Tieman Ray. Simmons disclosed that he personally held an 8,000 share short position in BP stock. As BP's stock price went lower, Simmons was benefiting financially amid fears of bankruptcy. During a July 7, 2010, interview on CNBC Simmons claimed that scientists were reporting the flow rate from the oil spill was "spewing 120,000 barrels a day into the Gulf" and that there have been estimates that we have "lost oxygen for 40% of the Gulf of Mexico". He further claimed that the relief wells will not stop the oil spill. A week later, during a July 15, 2010 interview with KPFK – Pacifica Los Angeles, Simmons asserted that the relief wells and the capping process on the Macondo wellhead are publicity stunts and that the real vent is up to ten miles (16 km) away. He said that an enormous pool of crude oil is accumulating below the sea floor, releasing poisonous gases and waiting to be whipped up by a hurricane. Previously, on May 26, 2010, Matthew Simmons was a guest on 'The Dylan Ratigan Show' on MSNBC, where he explained his reasons for believing that the Deepwater Horizon oil spill involved not only the leak being monitored by BP's video-camera-equipped ROVs remotely operated vehicles, but another, much bigger leak, several miles away.

Wikileaks cable mention

The Guardian reported that Simmons was mentioned in a leaked U.S State Department cable dated November 2007:

COMMENT: While al-Husseini believes that Saudi officials overstate capabilities in the interest of spurring foreign investment, he is also critical of international expectations. He stated that the IEA's expectation that Saudi Arabia and the Middle East will lead the market in reaching global output levels of over 100 million barrels/day is unrealistic, and it is incumbent upon political leaders to begin understanding and preparing for this "inconvenient truth." Al-Husseini was clear to add that he does not view himself as part of the "peak oil camp," and does not agree with analysts such as Matthew Simmons. He considers himself optimistic about the future of energy, but pragmatic with regards to what resources are available and what level of production is possible. While he fundamentally contradicts the Aramco company line, al-Husseini is no doomsday theorist. His pedigree, experience and outlook demand that his predictions be thoughtfully considered.

Death Simmons was found dead on August 8, 2010, in his hot tub. An autopsy by the state medical examiner's office the next day concluded that he died from accidental drowning with heart disease as a contributing factor.
