Oil Spill Now Covering More Than 1,800 Square Miles

NEW ORLEANS — Coast Guard officials said Monday afternoon that the oil spill near Louisiana was now covering more than 1,800 square miles of the Gulf of Mexico, and they have been unable to engage a mechanism that could shut off the well thousands of feet below the ocean’s surface.

The response team was trying three tacks to address a spill caused by an explosion on an oil rig last week: one that could stop the leaks within hours, one that would take months, and one that would not stop the leaks but would capture the oil and deliver it to the surface while permanent measures were pursued.

On Sunday morning, officials began using remote-controlled vehicles to try to activate the blowout preventer, a 450-ton valve sitting at the wellhead, 5,000 feet below the ocean’s surface. The blowout preventer can seal off the well to prevent sudden pressure releases that possibly led to the explosion on the rig last Tuesday night.

If successful, engaging the blowout preventer could seal the well Monday or Tuesday.

The flow of oil from the leaks is about 42,000 gallons of oil a day. The authorities said it was still unclear what caused the explosion. Eleven crew members are missing and presumed dead.
