As we speak, we are exporting American crude oil out of the port of Valdez ,Alaska to far east ports in Japan and Taiwan. There is a tanker in exess of 850 ft lng leaving every six days. Vessels such as the Denali, Prince William Sound, and others alternate their runs between U.S. coastal and foreign.
As for product, (diesel ,gas,glycol) we have been sending loads of American product to Israel since 1974 by an agreement signed by Henry Kissenger, Edmund Muskie, and Dept of Interior. This product will continue to be sent there at a lower price than American consumers. That is part of the deal. It is quietlyrenewed every three years.
Expanding drilling on the North Slope doubtfully will not solve any problems , because this oil if extracted, will go on the world market. The companies are now multi national, and the stockholders are also . There are no longer any national regulations to channel American resources.
The hope for lower oil prices will come when the Russians finish building their pipeline from the Caspian Sea to the sea of Japan (all in Russian territory) This is the second largest deposit in the world tat is not yet literally in the pipeline..
