A gas leak on a North Sea oil platform has been stopped wednesday, after more than seven weeks.  Heavy mud was pumped into the well in an attempt to stop the leak on Total's Elgin platform, 150 miles from scottland.  Gas had been escaping from the site since late March. Reporters say the leak cost Total around $3 million a day in relief operations and lost net income.

The French firms chief executive Christopher de Margerie has said the Elgin leak would cost the company more than $300 million in lost production in a worst-case, where production did not restart before the end of the year.
