The US Department of Interior has given Shell conditional approval to resume exploration drilling offshore Alaska after a break of two years. The company's previous campaign was curtailed following damage to its contracted rig. Shell's program, said to be in around 140 ft (42.6 m) of water, will be subject to strict environmental regulation. At OTC last month, Shell's executive vice president Ann Pickard said the company plans to drill two wells in the Chukchi Sea this year.
