Stopping North Sea gas leak 'may take six months'         Mar 27, 2012  -   Source: Euronews The oil giant Total says it may take six months to stop a gas leak on the abandoned Elgin rig in the North Sea off Scotland. Engineers are looking at two options: drilling a relief well or a faster but riskier method. A cloud of gas surrounds the platform which lies 240 kilometres east of Aberdeen and accounts for more than five per cent of Britain's total oil production.
