From the article cited from 'RealClearPolitics' in the original posters message:
It will do nothing for today's or tomorrow's pump prices. The U.S. Energy Department says it: Drilling in these previously banned offshore areas "would not have a significant impact on domestic crude oil and natural gas production or prices before 2030."
That sure looks like someone says 20 years from now.
That's saying there won't be a significiant impact on prices for 20 years, not that oil won't start flowing for 20 years.
I believe EIA's analysis shows there won't be a significant impact on prices at all. A peak of 1 million barrels a day, when the world already consumes 85 million a day, won't lower prices by much. In fact by 2030 we'd better have got oil production about 100 million barrels a day or we'll be in real trouble.
If you don't explore for the oil then how do you know how many millions of barrels a day of oil is out there?
Because you don't have to drill test wells to have some idea where oil is to be found. Western oil companies have been prospecting for oil for over a century, they have a pretty good idea what sort of rock formations hold it.
even 1-2 million barrels a day in 2-5 years is a huge help.
Again you are making up numbers. The forecast is 1 million barrels a day in 20 years, nothing in 2 years and possibly 100,000 barrels a day in 5 years.
why not do it?
I think they should. The counter argument would be that it will raise unreasonable expectations, which will cause people not to try so hard to conserve oil now. With the talk of 2 million barrels a day in 2 years, and the silly claims that the president caused the oil price to fall $30 a barrel just by signing the bill, that argument makes a lot of sense.
I think they should allow drilling in ANWR and the OCS. I just think people should realise it's not going to make much difference in the grand scheme of things.
There may be fields that surpass all the oil that has been discovered so far.
I doubt it. All the super fields were discovered a long time ago.
Ghawar in Saudi was discovered in 1948, Samotlor in Russia in 1965, Burgan (Kuwait) in 1938, Cantarell (Mexico) in 1976. There haven't been really major discoveries for a long time.
Put simply the oil companies have a rough idea where to look, and they've already looked in the good places. There is oil out there, but it tends to be in much smaller fields. That's why the amount of oil discovered these days is way down on the heydays of the 50s and 60s.
