Cramped on Land, Big Oil Bets at Sea

Rising prices have spurred offshore exploration. By 2008, about 8% of global oil production came from deepwater fields.

Yet even the biggest deepwater projects aren’t enough to put a dent in global supply problems on their own. The world’s largest deepwater platform, BP’s Thunder Horse in the Gulf of Mexico, produces 250,000 barrels of oil a day, just 0.3% of global consumption.

“These discoveries are changing the debate,” says Ed Morse, chief economist for LCM Commodities, a brokerage firm. What remains unclear, he says, is whether the deepwater projects will ensure that new discoveries continue to meet demand.

Many in the industry argue the new fields have expanded the limits of where the industry can find oil, potentially delaying a decline in global production.
