HOUSTON (ICIS)--The oil leak in Lake Grande Ecaille Bay has been secured, the US Coast Guard (USCG) announced on Thursday, nearly two days after a marine vessel collided with the shut-in wellhead at a Swift Energy field in Louisiana on Tuesday night.

Responders with Wild Well Control were able to secure the well shortly after the arrival of a specialised equipment barge, the USCG said, adding that crews continue cleanup operations. 

More than 1,200 gal (4,500 litres) of oily-water mixture have been recovered, and responders have deployed 4,880 feet (1,500 metres) of boom around the wellhead and all sensitive areas, the USCG said.

The estimated maximum potential discharge from the wellhead was fewer than 1,260 gal of crude oil and 1,134 gal of oily water per day, the USCG said.

“Our primary objectives, as we continue this response, are to ensure the safety of response personnel and the public, secure the source of the discharge,” said Lieutenant Commander Lushan Hannah, incident commander for the operation. “We will continue to maintain effective containment of recoverable liquids, continually assess the incident’s potential, as well as identify and protect areas that are environmentally sensitive and areas with historical or cultural significance.”

Swift Energy said Tuesday night’s collision occurred at its Lake Washington field in Plaquemines Parish, Louisiana.

“This collision damaged the integrity of the wellhead and resulted in an outflow of water, oil and natural gas,” the company said. “Swift Energy’s Incident Command Team was activated and responded to the situation during the night.”

No injuries were reported.

The well was shut in January 2008, according to the company’s website.
