If and when UK/US pull out of IRAQ then production there will likely fall
Production in Iraq has already fallen. From 2.5 million barrels a day to just over 1.5 million. Of which anywhere between 100,000 and 300,000 barrels are stolen and smuggled out of the country. It's hard to imagine production falling much further when the US and UK forces leave.
Given that the extraction technology used in Iraq is extremely outdated, it is estimated that once the Production Sharing Agreements (PSAs) are put in place and western oil companies move in, production could easily hit 3.5 million barrels a day.
That's for existing fields. The US Energy Information Administration (EIA) estimates Iraqi proven oil reserves to be in the region of 112 billion barrels. The second largest proven oil reserves in the world behind Saudi Arabia. However, 90% of the region is still relatively unexplored. The EIA conservatively estimate that exploration could yield another 100 billion barrels.
So it is feasible that within a five to ten year time frame, Iraqi oil production could hit 10 million barrels a day. Potentially offsetting production declines in Mexico and Saudi Arabia.
Even a second Saudi Arabia coming online doesn't change the essential facts. Oil is a limited resource for which it is becoming increasingly difficult to increase supply (otherwise why would oil companies be exploring five miles deep in the Atlantic ocean or on the frozen wastes of Siberia etc.) and for which demand continues to grow.
Eventually, existing oil prices and greater will be justified on a supply/demand basis. However, we are paying high oil prices now for something that will be in short supply in several years. This isn't an item we can store very easily so forward discounting should be relatively minimized. Very few market participants are buying to store and sell later and if they are, why are they bidding on front month contracts?.
I think it is simply sentiment. An Internet bubble-survivor stock I own recently reported a second year of good earnings. It now trades at over $2, up from $1 last year. Back in the heady dotcom bubble days traders paid over $160 a share for the company despite it being deeply in debt with no earnings whatsoever. No doubt many of those traders thought the same thing - the Internet will revolutionize the global supply chain business. Indeed it has. So why aren't those traders flocking back to the company?
The possibility, or even the certainty of, a peak-oil situation manifesting at some point in the next twenty years in no way guarantees that oil will always trade at over $50 a barrel during this period.
