How much untapped crude oil is there in the US?

I heard a news report some years ago that if we utilized every drop of oil that is in the US it would only last us for one year. But I read other reports on the internet say that we have one of the largest untapped oil supplies in the world.

    If you really want a fairly accurate assessment, I would suggest looking at the USGS site which documents current reserves in the US. I’ve seen estimates that the total untapped reserves are up to 2.3 trillion barrels in US reserves and that is a total figure including oil shales and tar sands which does not necessarily translate into oil than can be extracted at current prices or the foreseeable future. At least, there’s more than enough oil to last for more than a year.

    Some other sites with related info on reserves……

    "The U.S. is sitting on the world’s largest, untapped oil reserves — reservoirs which energy experts know exist, but which have not yet been tapped and may not be attainable with current technology. In fact, such untapped reserves are estimated at about 2.3 trillion barrels, nearly three times more than the reserves held by Organization of Petroleum Exporting Countries (OPEC) nations and sufficient to meet 300 years of demand — at today’s levels — for auto, truck, aircraft, heating and industrial fuel, without importing a single barrel of oil."

    In addition, there are methods to convert the billions of tons of garbage and waste products that we produce every year…and rising…into oil rather than bury them in the ground along with methods of producing plentiful bio-fuels from crops or crop wastes, algae, etc….

    the problem with the question is a lot of oil isnt found yet. My dad is an exploration geologist. he says there are rather large pockets scattered around. he has a few ideas of VERY large reserves as well.

    i dont believe that we would use it all up in 1 year.
