Both the Alaskan OCS and Gulf OCS will continue to generate revenue for the United States for many years to come. According to Interior Depart- ment estimates, the U.S. OCS contains 8.5 billion barrels of oil and 29.3 trillion cubic feet of natural gas in proved and unproved reserves and another 86 billion barrels of oil and 420 trillion cubic feet of natural gas in as yet undiscovered resources.
Such vast resources will continue to generate billions of dollars in royalty revenue for the United States. A recent report by the Institute for Social and Economic Research at the University of Alaska evaluated further development of the Alaskan OCS, focusing on the Beaufort Sea OCS and the Chuk- chi Sea OCS, the two OCS areas off the northern shore of Alaska. Assuming a minimum royalty rate of 12.5 percent, mineral exploitation in these two areas would generate almost $92 billion in royalty revenue over the next 50 years.
