In what environmental campaigners are calling “a huge break” for the Arctic region and by extension the world’s climate, the Royal Dutch Shell oil company announced on Monday it would end exploratory drilling in the Chukchi Sea after disappointing results from its controversial operations in the Alaskan waters that took place this summer.

In a corporate press statement released Monday, the company said that its drilling vessel—located approximately 150 miles offshore and in about 150 feet of water—had “successfully” drilled an exploratory well to the depth of 6800 feet. Though the company claimed it “found indications of oil and gas,” it said the amount was “insufficient to warrant further exploration” and said the prospected site will now be “sealed and abandoned.”

Further, citing “high costs associated with the project” as well as what it called “the challenging and unpredictable federal regulatory environment,” Shell said it will now “cease further exploration activity in offshore Alaska for the foreseeable future.”

The announcement comes as a huge blow to Shell, notes the Associated Press, which has spent an estimated $7 billion on its Arctic efforts and was counting on offshore drilling in Alaska to help drive future revenue.

Though a Shell official called the outcome “disappointing,” those opposed to offshore oil and gas development in the Arctic responded quite differently.

“Polar bears, Alaska’s Arctic and our climate just caught a huge break,” said Miyoko Sakashita, oceans program director for the Center for Biological Diversity, in response to the news. “Here’s hoping Shell leaves the Arctic forever. Drilling for oil there is inherently dangerous and will only drive the world deeper into the climate crisis. If we’re going to leave behind a livable planet, we need to leave that oil in the ground today, tomorrow and always.”
