But Obama's tough-guy act offers no guarantee that oil giants like BP won't be permitted to repeat the same mistakes that led to the nightmare in the Gulf. Indeed, top environmentalists warn, the suspension of drilling appears to be little more than a stalling tactic designed to let public anger over BP's spill subside before giving Big Oil the go-ahead to drill in an area that has long been off-limits: the Arctic Ocean. The administration has approved plans by both BP and Shell Oil to drill a total of 11 exploratory wells in the Chukchi and Beaufort Seas above Alaska — waters far more remote and hostile than the Gulf. Shell's operations could proceed as soon as the president's suspension expires in January. And thanks to an odd twist in its rig design, BP's drilling in the Arctic is on track to get the green light as soon as this fall.

Ken Salazar, the Interior secretary whose staff allowed BP to drill in the Gulf based on pro-industry rules cooked up during the Bush years, has made no secret of his determination to push the "frontier" of oil drilling into the Arctic. The region's untapped waters are believed to hold as much as 27 billion barrels of oil — an amount that would rival some of the largest oil fields in the Middle East. "Everything I've heard internally, from sources within both the administration and industry, tells me that the administration is all over wanting these guys out in the Arctic Ocean," says Rick Steiner, a top marine scientist in Alaska who helped guide the response to the Exxon Valdez spill. "They're trying to solve this political problem with this Gulf spill in time to get these guys out in the Arctic next summer."

Here's what BP has in store for the Arctic: First, the company will drill two miles beneath its tiny island, which it has christened "Liberty." Then, in an ingenious twist, it will drill sideways for another six to eight miles, until it reaches an offshore reservoir estimated to hold 105 million barrels of oil. This would be the longest "extended reach" well ever attempted, and the effort has required BP to push drilling technology beyond its proven limits. As the most powerful "land-based" oil rig ever built, Liberty requires special pipe to withstand the 105,000 foot-pounds of torque — the equivalent of 50 Mack truck engines — needed to turn the drill. "This is about as sexy as it gets," a top BP official boasted to reporters in 2008. BP, a repeat felon subject to record fines for its willful safety violations, calls the project "one of its biggest challenges to date" — an engineering task made even more dangerous by plans to operate year-round in what the company itself admits is "some of the harshest weather on Earth."
