Thanks for the reference URL. I had visited this site last year. Notice in my original comments I said nothing of how much expected oil could be extracted over time. My last comments bear out in simple terms that the total extraction of oil at area 2002, over the expected life, simply is not an significant amount of oil compared to the daily US needs. That is all I was trying to bring out. Perhaps my grammer did not bring out the point I strived to communicate. At any rate, like I say, I am all for the drilling to take place.
ANWR, if the leases are let in the next year, would keep the supply of North Slope oil at a fairly constant level of about half of what Prudhoe production was at the beginning for the next 20 years while the Prudhoe field amd NPR fields dry up. After that is unknown, but if ANWR does not go into production the North Slope production will fall to nothing sometime between 10 to 20 years from now.
