HOUSTON (Reuters) - Royal Dutch Shell said an oil sheen near two of its offshore Gulf of Mexico oil and natural gas platforms was estimated to total about six barrels of oil and that its seabed wells showed no signs of leaks.
Shares of Shell traded on the New York Stock Exchange were up 39 cents, or less than 1 percent, at $68.14 at midday. The stock closed down less than 1 percent in London after falling as much a 5 percent earlier in the day, temporarily erasing about $5 billion in value from Europe's largest oil company by market capitalization.
