I didn't read all of the third link, but the first two agree with what I said.. very little leaves the country. The first link shows 2.7% exported.
Alaskan Oil Exports 1996 to 2004
Destination Amount (in million barrels)
South Korea 46.15
Total Exports 95.49
Total Alaskan Production 1996 to 2004 = 3,549 million barrels
ANSWER: Despite the opening of new fields, oil production in Alaska has steadily declined in recent years. The amount flowing through the trans-Alaska pipeline has fallen from a high of more than 2 million barrels a day in 1988 to 740,000 barrels a day in 2007, according to the Alyeska Pipeline Service Co.
After-tax profits go to the oil companies and royalties go to resource owners - mainly the state of Alaska, whose budget relies heavily on the money from oil production. About $2 billion in oil royalties went into the state's general fund this past year.
Other resource owners include the federal government and private landowners - parties that generally support drilling in ANWR because it would add to the dwindling supplies of the state's existing oil fields.
The crude oil that flows down the 800-mile pipeline is picked up by tankers in the port of Valdez. According to state officials, the bulk of the crude is transported to West Coast refineries, with a small percentage remaining in Alaska and an unknown amount going overseas.
According to the CIA's World Factbook, the U.S. exported 1.048 million barrels of crude per day in 2004 - which amounts to about 12 percent of domestic production - and imported 13.15 million barrels a day that same year. It's unclear how much of the exported oil originated in Alaska.
A group of oil companies paid for the pipeline to be built in the late 1970s at a cost of $8 billion. Interest holdings in the pipeline have changed hands several times and today three companies own much of the pipeline and most of Alaska's oil leases: BP PLC, Exxon Mobil Corp. and ConocoPhillips.
