A rig off Scotland has an uncontrolled venting of gas tha will take a long time to stop.
A sheen of liquid gas (?) is reported on the surrounding sea.
Nearby platforms have been evacuated.
The gas, mostly methane is twenty times worse than CO2 as a greenhouse gas.
A two-mile air and sea exclusion zone was imposed around the Elgin and the connected Rowan Viking drilling rig 150 miles off Aberdeen.

Rescued personnel said yesterday the sea was "boiling and bubbling" with escaping gas, indicating a subsea leak under the Elgin.

Last night, Total had called in a Texan team to cap the well and contain the leak.
