I was told by an engineer who use to work for an oil company that we had at least 200 years of oil and 1000 years of natural gas. Now I'm not exactly sure how, or where he got those numbers, but I trust them enough to not think it's freak out time.
Well, we consume roughly 7 billion barrels a year and our reported proven reserves are only about 24 billion barrels so that comes out to about three years worth. 200 years would be 1.4 trillion barrels. According to numbers on Wiki http://en.wikipedia.org/wiki/List_of_countries_by_proven_oil_reserves total proven reserves for the entire world are 1.3 trillion barrels. But proven reserves are not necessarily a total of all known drops of oil in the ground- that is the amount which is believed recoverable at a profit given the current price and technology. Proven reserves can increase simply by having the price of oil go up. One source may be profitable at $50 a barrel and another may be profitable at $500 a barrel. If you are looking at an oil price of $90 a barrel, we have about three or so years worth (assuming we don't import a drop) while if the price soars, then some other sources may be financially worth going after.
As for Natural Gas, one estimate by the Heartland Institute published this week indicates that the US has about 650 trillion cubic feet of recoverable natural gas and currently produces 3 trillion a year and imports about 11% of total consumption. That makes it about 3.3 trillion used a year or 200 years which is quite a lot (maybe not 1000 years but enough not to run out by the time I die). http://www.heartland.org/full/29277...ordable_Energy_Future_Says_DOE_Official_.html
Coincidentally, an article just hit the newswire about newer drilling techniques which may allow the extraction of more oil- fracturing which has been used for natural gas. You drill down and blast in water, sand, and chemicals to try to knock the oil or gas loose so you can pump it up. They don't say what the costs are but that it is "profitable"- more so than spending $1 billion a hole to drill in deep Gulf of Mexico waters.
A new drilling technique is opening up vast fields of previously out-of-reach oil in the western United States, helping reverse a two-decade decline in domestic production of crude.
Companies are investing billions of dollars to get at oil deposits scattered across North Dakota, Colorado, Texas and California. By 2015, oil executives and analysts say, the new fields could yield as much as 2 million barrels of oil a day — more than the entire Gulf of Mexico produces now.
This new drilling is expected to raise U.S. production by at least 20 percent over the next five years. And within 10 years, it could help reduce oil imports by more than half, advancing a goal that has long eluded policymakers.
"That's a significant contribution to energy security," says Ed Morse, head of commodities research at Credit Suisse.
Oil engineers are applying what critics say is an environmentally questionable method developed in recent years to tap natural gas trapped in underground shale. They drill down and horizontally into the rock, then pump water, sand and chemicals into the hole to crack the shale and allow gas to flow up.
Because oil molecules are sticky and larger than gas molecules, engineers thought the process wouldn't work to squeeze oil out fast enough to make it economical. But drillers learned how to increase the number of cracks in the rock and use different chemicals to free up oil at low cost. "We've completely transformed the natural gas industry, and I wouldn't be surprised if we transform the oil business in the next few years too," says Aubrey McClendon, chief executive of Chesapeake Energy, which is using the technique.
Petroleum engineers first used the method in 2007 to unlock oil from a 25,000-square-mile formation under North Dakota and Montana known as the Bakken. Production there rose 50 percent in just the past year, to 458,000 barrels a day, according to Bentek Energy, an energy analysis firm.
It was first thought that the Bakken was unique. Then drillers tapped oil in a shale formation under South Texas called the Eagle Ford. Drilling permits in the region grew 11-fold last year.

That would make them the fifth- and sixth-biggest oil fields ever discovered in the United States. The top four are Prudhoe Bay in Alaska, Spraberry Trend in West Texas, the East Texas Oilfield and the Kuparuk Field in Alaska.
The fields are attracting billions of dollars of investment from foreign oil giants like Royal Dutch Shell, BP and Norway's Statoil, and also from the smaller U.S. drillers who developed the new techniques like Chesapeake, EOG Resources and Occidental Petroleum.
Last month China's state-owned oil company CNOOC agreed to pay Chesapeake $570 million for a one-third stake in a drilling project in the Niobrara. This followed a $1 billion deal in October between the two companies on a project in the Eagle Ford.
With oil prices high and natural-gas prices low, profit margins from producing oil from shale are much higher than for gas. Also, drilling for shale oil is not dependent on high oil prices. Papa says this oil is cheaper to tap than the oil in the deep waters of the Gulf of Mexico or in Canada's oil sands.
The four billion barrels in each of the Bakkan and Eagle fields would let us last just over another year on our own supplies over our current proven reserves- stretching our current supplies to last us alone without importing anything for over four years. Their estimated two million barrels a day peak production would almost cover ten percent of our current daily consumption of 21 million barrels. To be independent of imports at our current rate of consumption you need two Bakkans or Eagles every year into the forseable future but it is a start.
