cyclops, here is the information on ANWR.

The above says there is a 95% probability of 5.7 billion barrels, a 5% probability of 16 billion, and a mean of 10.3 billion barrels, which could translate into 600,000 to 1.9 million barrels per day at peak production. Production would last decades at some level, and would serve to replace and compliment the declining production of the North Slope.
You will notice that environmental groups or opponents always quote the 95% probability, but anyone that understands oil exploration and statistics knows there is an excellent chance for significantly more reserves and higher production rates.
The following link shows we currently produce only about 7.7 million barrels daily of the 19.7 consumed. Domestic production is projected to decline unless more reserves can be discovered and brought online. Even if we fail to increase production, ANWR could be a crucial piece of the puzzle in terms of maintaining as much domestic production as possible, which has huge impacts upon our national security, trade deficit, etc. At current domestic production levels, just 1 million barrels per day would constitute more than 13% of our entire domestic production, from just one geographic region. And if it turned out to be 1.5 million barrels, it would amount to almost 20% of all domestic production.
Obviously, this is no small potatoes, and is not trivial, miniscule, or meaningless, as the treehuggers persist in telling us. Anyone that understands oil reserves knows this is one major resource being ignored to our own detriment.
