Shell says it will cease Alaska offshore Arctic drilling

Royal Dutch Shell will cease exploration in Arctic waters off Alaska's coast following disappointing results from an exploratory well it just completed.

Shell found indications of oil and gas in the well in the Chukchi Sea about 80 miles off Alaska's northwest coast, the company said on Sept. 28 in a release from The Hague, Netherlands. However, the petroleum was not in quantities sufficient to warrant additional exploration in that portion of the basin, the company said.

"Shell continues to see important exploration potential in the basin, and the area is likely to ultimately be of strategic importance to Alaska and the U.S.," said Marvin Odum, president of Shell USA, in the announcement. "However, this is a clearly disappointing exploration outcome for this part of the basin."

Shell will end exploration off Alaska "for the foreseeable future," the company said.

The decision reflects the results of the exploratory well in the Burger J lease, the high costs associated with Alaska offshore drilling and the challenging and unpredictable federal regulatory environment in offshore Alaska, the company said.

Shell has spent upward of $7 billion on Arctic offshore development in the Chukchi and Beaufort seas.

Sept. 28 was Shell's final day to drill this year in petroleum-bearing rock under its federal permit. Regulators required Shell to stop a month before sea ice is expected to re-form in the lease area.

The company reached a depth of 6,800 feet with the exploratory well drilling in about 150 feet of water.

Environmental groups oppose Arctic offshore drilling and say industrial activity and more greenhouse gases will harm polar bears, walrus and ice seals.
