BP Oil Leak May Last Until Christmas in Worst Case Scenario

BP Plc’s failure since April to plug a Gulf of Mexico oil leak have prompted forecasts the crude may continue gushing into December in what President Barack Obama has called the greatest environmental disaster in U.S. history.

BP’s attempts so far to cap the well and plug the leak on the seabed a mile below the surface haven’t worked, while the start of the Atlantic hurricane season this week indicates storms in the Gulf may disrupt other efforts.

“The worst-case scenario is Christmas time,” Dan Pickering, the head of research at energy investor Tudor Pickering Holt & Co. in Houston, said. “This process is teaching us to be skeptical of deadlines.”

Ending the year with a still-gushing well would mean about 4 million barrels of oil spilled into the Gulf, based on the government’s current estimate of 12,000 to 19,000 barrels leaking a day. That would wipe out marine life deep at sea near the leak and elsewhere in the Gulf, and along hundreds of miles of coastline, said Harry Roberts, a professor of Coastal Studies at Louisiana State University.

So much crude pouring into the ocean may alter the chemistry of the sea, with unforeseeable results, said Mak Saito, an Associate Scientist at Woods Hole Oceanographic Institution in Massachusetts.
