Shell begins drilling in Alaska’s Chukchi Sea
BY ANGEL GONZALEZ
ANCHORAGE, Alaska — After a six-year wait and clearance of countless hurdles, Royal Dutch Shell ‘s U.S. unit said it had begun drilling in Alaska’s Chukchi Sea.
This is the first time in more than two decades that the oil industry gets access to the U.S. offshore Arctic. If successful, Shell’s foray could pave the way for the exploitation of one of the world’s last oil frontiers.
Shell’s bid to tap the Arctic’s vaunted offshore oil and gas riches has met with resistance from environmentalists, strict scrutiny from cautious regulators and persistent sea ice. Now the Anglo-Dutch oil giant must cram as much drilling activity as it can in a short window that lasts through late September in the Chukchi Sea and late October in the Beaufort Sea, depending on weather forecasts.
One of the two drillships Shell has leased for the Alaska drilling campaign, the Noble Discoverer, early Sunday began drilling the so-called top hole of the Burger prospect. It will include a 1,400-ft-deep pilot well and a 20-by-40-ft hole right beneath the seabed, which will house the BOP. Burying the blow-out preventer in that fashion protects it from sea ice, Shell said.
The process could take about two weeks, after which it could either proceed to drill the entire well to a depth of between 7,000 and 9,000 ft, or move the rig to another location and drill a similar top hole, said Peter Slaiby, Shell’s vice president for Alaska operations. The process to drill a well down to its target depth, from initial work to completion, lasts about a month, he said. This year Shell plans to do work in up to five wells, three in the Chukchi Sea and two in the Beaufort Sea.
Right now, the company has permission from U.S. authorities to drill only the top part of the wells; a permit to drill in oil-bearing areas can be granted onl after an Arctic spill-containment system is in place, the U.S. Department of Interior has said. The containment system is being tested in Washington State and would require about two weeks to sail to the location, Shell said.
The U.S. government is closely watching the operation; regulators with the Bureau of Safety and Environmental Enforcement, which oversees offshore drilling, were present aboard the drillship that began working Sunday. “The public wants to be assured this is done right,” Mr. Slaiby said.
Mr. Slaiby added that drilling these wells, which are located in shallow waters, does not represent major technical challenges, and that sea conditions are more benign here than in the North Sea, for example. The challenge comes from the remoteness of the operation, ice features and low temperatures, he said.
Shell’s efforts, however, continues to be strongly criticized by environmentalists. Dan Howells, Greenpeace’s deputy campaigns director, said in a statement that “whatever Shell is able to do in the narrow window between now and when the sea ice returns, it won’t erase the clear evidence we’ve seen in the past two months that there’s no such thing as safe drilling in the Arctic.”
Mr. Howells pointed to logistical failures in Shell’s drilling plan. In July, the Noble Discoverer broke loose from its moorings while anchored off the Alaskan coast. “They’ve only proven one thing this summer, that oil companies are simply not equipped to deal with the unique challenges of operating in the Arctic,” Mr. Howells said.
