ConocoPhillips Alaska employees evacuated due to prolonged natural gas leak on the North Slope

The leak was detected early Friday at the drill site CD1, 8 miles north of the village of Nuiqsut. “There are no reports of injury or environmental impact to the tundra or wildlife,” the company’s statement said. “Air quality continues to be monitored and no natural gas has been detected outside of the CD1 pad.” The gas leak happened below gravel, and its cause and scale are under investigation, Conoco said. The company said it is using natural gas detection monitors at the CD1 pad, and conducting infrared surveys from the air.
