Royal Dutch Shell hopes to tap into a huge new potential source of oil off the north coast of Alaska. Federal officials have given Shell approval for limited work in the Beaufort Sea. A Shell drill ship, the Kulluk, is positioned in the Beaufort waiting for the whaling season to end. After many months of study, the Bureau of Safety and Environmental Enforcement already gave Shell approval for similar work in the Chukchi Sea. The company can't drill into petroleum zones until its spill response barge is in place. A containment dome on the barge was damaged in tests last weekend. Shell says it will drill pilot holes and perform other well preparation work this year. The company hopes to tap into an estimated 26 billion barrels of recoverable oil and 130 trillion cubic feet of natural gas in U.S. Arctic waters.
