The amount of danger presented by the peak oil scenario depends on the future decline in oil production. That is, the peak oil scenario says (based on observations from around the world) that after some point of oil extraction and production the worlds oil production will inevitably enter a decline and that once world oil production begins to decline no way will it ever increase.
The timing of this decline depends on future oil discoveries. The more oil discovered in the future the further out into the future will be the peak, and hence the longer we have to find a solution. But it's rather difficult to accurately predict the future such as future oil discoveries, obviously.
The various estimates of when the oil peak occurs are all based on estimates of this prediction, what is the amount of future oil discovery.
For example: Between 1995 and 2005, nearly 110 Gb of conventional oil and NGL have been discovered. A reasonable, but optimistic, scenario is to assume that this pattern of discovery will remain the same for the next 22 years. However they go on to say this is an unreasonable assumption because it's more likely that the rate of discovery will also decline over time.
Specifically the world peak of oil discovery occurred in 1964 and has been declining ever since.
Re: Predicting Future Supply from Undiscovered Oil
Global Peak Oil is now and production decline will hit 6% within a few years, and be steeper.
Energy investment banker Matthew Simmons, like ASPO-Ireland, notes that today’s low oil prices and credit shortage will reduce investments needed for oil production, resulting in lower oil production in the future, followed by increasing oil prices as demand out strips supply, which will then cause another economic downturn in the future. Simmons also notes that the aging oil infrastructure of drilling rigs, rusting platforms, pipelines, and refineries must be renovated, requiring trillions of dollars in investments at a time when credit is tight..
Global crude oil production had been rising briskly until 2004, then plateaued for four years. Because oil producers were extracting at maximum effort to profit from high oil prices, this plateau is a clear indication of Peak Oil.
Then in August and September of 2008 while oil prices were still very high, global crude oil production fell nearly one million barrels per day, clear evidence of Peak Oil (See Rembrandt Koppelaar, Editor of "Oil Watch Monthly," December 2008, page 1) http://www.peakoil.nl/wp-content/uploads/2008/12/2008_december_oilwatch_monthly.pdf.
Peak Oil is now.

Oil production will now begin to decline terminally.
Within a year or two, it is likely that oil prices will skyrocket as supply falls below demand. OPEC cuts could exacerbate the gap between supply and demand and drive prices even higher.
Independent studies indicate that global crude oil production will now decline from 74 million barrels per day to 60 million barrels per day by 2015. During the same time, demand will increase. Oil supplies will be even tighter for the U.S. As oil producing nations consume more and more oil domestically they will export less and less. Because demand is high in China, India, the Middle East, and other oil producing nations, once global oil production begins to decline, demand will always be higher than supply. And since the U.S. represents one fourth of global oil demand, whatever oil we conserve will be consumed elsewhere. Thus, conservation in the U.S. will not slow oil depletion rates significantly.
Alternatives will not even begin to fill the gap. There is no plan nor capital for a so-called electric economy. And most alternatives yield electric power, but we need liquid fuels for tractors/combines, 18 wheel trucks, trains, ships, and mining equipment. The independent scientists of the Energy Watch Group conclude in a 2007 report titled: “Peak Oil Could Trigger Meltdown of Society:”
"By 2020, and even more by 2030, global oil supply will be dramatically lower. This will create a supply gap which can hardly be closed by growing contributions from other fossil, nuclear or alternative energy sources in this time frame."
With increasing costs for gasoline and diesel, along with declining taxes and declining gasoline tax revenues, states and local governments will eventually have to cut staff and curtail highway maintenance. Eventually, gasoline stations will close, and state and local highway workers won’t be able to get to work. We are facing the collapse of the highways that depend on diesel and gasoline powered trucks for bridge maintenance, culvert cleaning to avoid road washouts, snow plowing, and roadbed and surface repair. When the highways fail, so will the power grid, as highways carry the parts, large transformers, steel for pylons, and high tension cables from great distances. With the highways out, there will be no food coming from far away, and without the power grid virtually nothing modern works, including home heating, pumping of gasoline and diesel, airports, communications, and automated building systems.
