The Coast Guard says a wellhead damaged earlier this week off Plaquemines Parish has been secured.
Ensign Tanner Stiehl says Wild Well Control crews secured the well shortly after a specialized barge arrived Thursday in Lake Grande Ecaille Bay, nine miles southwest of Port Sulphur.
The wellhead owned by Houston-based Swift Energy Co. was damaged Tuesday by one of the company's crewboats. Stiehl says skimmer boats have since collected more than 1,200 gallons of oily water. He says 4,880 feet of boom was set out to contain the spill and keep it out of marshes.
Officials say the wellhead released less than 840 gallons of oil a day. Swift says the well was producing about 756 gallons of oil a day in January 2008, when it was shut in.
