Tough regulation slows Arctic drilling to a glacial pace.

FT: Shell’s programme is riven with uncertainty in the aftermath of the grounding of its rig. Others are not drilling at all. Canada’s federal regulator, the National Energy Board, is requiring a Same Season Relief Well capability (the technique that finally stopped Macondo). The drilling season in the Beaufort Sea is as little as 100 days, and some wells require three summers. SSRW capability seems is proving a little difficult to prove.
