OFFSHORE ENERGY | Environmental group Greenpeace has located two large methane leaks at an old offshore well site in the UK North Sea.
Greenpeace said on Monday that its patrol ship Esperanza located two “gas-emitting craters” on the seabed.
According to the organization, the leaks were caused by a blowout during a drilling operation in 1990, and they are still releasing the powerful greenhouse gas into the atmosphere.
The craters lie at about 100 metres water depth and are between 50 and 15 meters in diameter and up to 20 and 9 meters deep, respectively.
