The Energy Information Administration (EIA) has published a report on the potential for oil and gas development in the Arctic (found here). It concludes, in part:
The good news is that the Arctic holds about 22 percent of the world’s undiscovered conventional oil and natural gas resources, based on the USGS mean estimate. The bad news is that: (1) the Arctic resource base is largely composed of natural gas and natural gas liquids, which are significantly more expensive to transport over long distances than oil; (2) the Arctic oil and natural gas resources will be considerably more expensive, risky, and take longer to develop than comparable deposits found elsewhere in the world; (3) unresolved Arctic sovereignty claims could preclude or substantially delay development of those oil and natural gas resources where economic sovereignty claims overlap; and (4) protecting the Arctic environment will be costly. The high cost and long lead-times of Arctic oil and natural gas development undercut the immediate importance of these sovereignty claims, while at the same time diminishing the economic incentive to develop these resources.
