There are still huge reserves left, of course. The problem is that as an oil well is depleted, it becomes harder to extract:

Energy return on energy investment
When oil production first began in the mid-nineteenth century, the largest oil fields recovered fifty barrels of oil for every barrel used in the extraction, transportation and refining. This ratio is often referred to as the Energy Return on Energy Investment (EROI or EROEI). Currently, between one and five barrels of oil are recovered for each barrel-equivalent of energy used in the recovery process. As the EROEI drops to one, or equivalently the Net energy gain falls to zero, the oil production is no longer a net energy source. This happens long before the resource is physically exhausted.
Note that it is important to understand the distinction between a barrel of oil, which is a measure of oil, and a barrel of oil equivalent (BOE), which is a measure of energy. Many sources of energy, such as fission, solar, wind, and coal, are not subject to the same near-term supply restrictions that oil is. Accordingly, even an oil source with an EROEI of 0.5 can be usefully exploited if the energy required to produce that oil comes from a cheap and plentiful energy source. Availability of cheap, but hard to transport, natural gas in some oil fields has led to using natural gas to fuel enhanced oil recovery. Similarly, natural gas in huge amounts is used to power most Athabasca Tar Sands plants. Cheap natural gas has also led to Ethanol fuel produced with a net EROEI of less than 1, although figures in this area are controversial because methods to measure EROEI are in debate.

Here's another:

Peak oil production—has it happened already?
Further information: List of oil fields
World Crude Oil Production 1960-2004. Sources: DOE/EIA, IEA
World Crude Oil Production 2001-2007.[39] Source: U.S. Energy Information Agency
As of July of 2007, analysts still disagree on whether peak production capacity has been reached.
The IEA projects non-OPEC production estimates for 2007 and 2008 to remain largely unchanged from July 2007, at 50.0 mb/d and 51.0 mb/d, respectively. Growth is projected to recede thereafter as the slate of verifiable investment projects diminishes. [40]“ The concept of peak oil production and its timing are emotive subjects which raise intense debate. Much rests on the definition of which segment of global oil production is deemed to be at or approaching peak. Certainly our forecast suggests that the non-OPEC, conventional crude component of global production appears, for now, to have reached an effective plateau, rather than a peak. ”
The report points to only a small amount of supply growth from OPEC producers, with 70% of the increase coming from Saudi Arabia, the UAE and Angola as security and investment issues continue to impinge on oil exports from Iraq, Nigeria and Venezuela.[40]
Analysts from Wood Mackenzie contend that maximum production of oil will not occur before 2014. Kate Dourian, Platts' Middle East editor, has a different opinion. "Some sources say half the world's oil has already been produced, whereas Saudi Aramco is saying there is still another trillion barrels out there." She is also quick to point out that politics has entered the equation. "Some countries are becoming off limits. Major oil companies operating in Venezuela find themselves in a difficult position because of the resource nationalism that's spreading. These countries are now reluctant to share their reserves"[41]

The Iraq war is about peak oil. As I said, we're just trying to claim resources now amd that's what this article indicates.
