Meaker: Era of oil wars - Africa is the new Saudi Arabia

Michael Meaker: Four-fifths of the world's oil supply comes from fields discovered before 1970. Growing competition for [remaining] oil may escalate to something as hot and dangerous as nuclear proliferation.

Despite an unwinnable war in Iraq, the US is still constructing at least five large permanent military bases there in order, according to evidence given to a US Congressional Committee, to control access to Gulf oil, including in Saudi and Iran. As one neocon recently put it, "one of the reasons we had no exit plan from Iraq is that we didn't intend to leave". The US is also trying to force through a new Iraqi oil law that would give western, primarily American, oil multinationals control of Iraqi oilfields for the next 30 years.

The US maintains 737 military bases in 130 countries under cover of the "war on terror" to defend American economic interests, particularly access to oil. The principal objective for the continued existence and expansion of Nato post-cold war is the encirclement of Russia and the pre-emption of China dominating access to oil and gas in the Caspian Sea and Middle East regions. It is only the beginning of the unannounced titanic global resource struggle between the US and China, the world's largest importers of oil (China overtook Japan in 2003).

The struggle has also spilled over into West Africa, reckoned to hold some 66 billion barrels of oil typically low in sulphur and thus ideal for refining. In 2005 the US imported more oil from the Gulf of Guinea than from Saudi and Kuwait combined, and is expected over the next 10 years to import more oil from Africa than from the Middle East. In step with this, the Pentagon is setting up a new unified military command for the continent named Africom. Conversely, Angola is now China's main supplier of crude oil, overtaking Saudi Arabia last year.

The authoritative International Energy Agency foresees an oil supply crunch within 5 years forcing up prices to unprecedented levels and greatly increasing western dependence on Opec. And the oil industry itself in its own report Facing the Hard Truths about Energy, produced by 175 authorities including all the heads of the world's big oil companies, for the first time predicted that oil and gas may run short by 2015.

The geopolitical implications of this gathering crisis for world oil supply 2010-15 are immense. The risk of further military interventions and conflicts in the Middle East is clearly high. Total world oil reserves are estimated at 2.5-2.9 trillion barrels, of which half has now been already consumed, while half of the 51 oil-producing countries reported output declines in 2006.

More.

NVDL: I recall recent predictions saying oil would last us till 2070. Shortages in 2015 I think are quite optimistic. I'd say they're more immiment...2009/2010 if not sooner.
