I'm a little surprised they'd bother. Massive spills were / are common in Russia. .. In December 2000, the State Duma's ecology committee revealed Russia loses 17 mm to 20 mm tpy of oil, or up to 5 % of total extraction, due to pipeline leakages. ... gasandoil.com A considerable proportion of the oil and gas extracted in the Russian Arctic never reaches the market. It is ejected into the natural environment either as a result of leakage and other accidents or in the normal course of operations. ..... cdi.org

Deepwater Horizon blast triggered by methane bubble, report shows Investigation reveals accident on Gulf of Mexico rig was caused when gas escaped from oil well before exploding The deadly blast on board the Deepwater Horizon oil rig in the Gulf of Mexico was triggered by a bubble of methane gas, an investigation by BP has revealed. A report into last month's blast said the gas escaped from the oil well and shot up the drill column, expanding quickly as it burst through several seals and barriers before exploding. The sequence of events, described in the interviews with rig workers, provides the most detailed account of the blast that killed 11 workers and led to more than 3 million gallons of crude oil pouring into the Gulf. Segments of the interviews conducted during BP's internal investigation were described in detail to the Associated Press by Robert Bea, a University of California Berkeley engineering professor who serves on a National Academy of Engineering panel on oil pipeline safety. He also worked for BP as a risk assessment consultant during the 1990s. He received the details from industry friends seeking his expert opinion. The revelations came as a giant funnel was lowered over the oil well in a bid to contain oil leaking from it. BP said it might take up to 12 hours for the 98-tonne, steel and concrete containment device to settle in place almost 1 mile (1.6km) below the surface. But the company added that the operation appeared to be going as planned. It is hoped that the structure will be able to collect as much as 85% of the leaking oil and begin funnelling it to ships above by Monday. But the BP chief executive, Tony Hayward, has warned there is no certainty the device will prove successful because it has not be tried at that depth. The cpmpany, which is also drilling a relief well to halt the leak, faces an equally daunting challenge to contain the political and financial fallout from the spill. The Obama administration has kept up the pressure on the oil giant, a move seen in part as a tactic to divert criticism of its own role in the disaster. Recent news reports have suggested the interior department exercised lax oversight in approving BP's operations in the Gulf, accepting too readily its claims there was little risk of an accident. guardian.co.uk
