NEW ORLEANS (AP) - The Coast Guard says a repair barge is heading to a wellhead damaged earlier this week off Plaquemines Parish.
Ensign Tanner Stiehl says he doesn't know when it's expected to arrive.
The wellhead owned by Swift Energy Co. was damaged Tuesday evening by a crewboat belonging to the same company.
Officials say it's releasing less than 840 gallons of oil a day. A statement from Swift says the well was producing about 18 barrels - 756 gallons - of oil a day in January 2008, when it was shut in.
Stiehl says skimmer boats have collected 1,200 gallons of oily water, which is being collected in a tank barge. He says 4,880 feet of boom have been set out to contain the spill and keep it out of marshes.
