Coast Guard, federal agencies responding to offshore oil spill

According to Coast Guard officials, the Coast Guard is responding to the report of a crude oil spill in the Gulf of Mexico.

Officials said four over flights were conducted throughout Saturday and have identified no additional visible oil.

They also said previously reported "sheens" have dissipated.

According to a release from the Coast Guard, Coast Guard and the responsible party are continuing to evaluate trajectory models to identify the potential location of any surface oil or sub-sea plumes.

Officials said Coast Guard Sector New Orleans learned about the spill from the National Response Center Friday.

The spill reportedly came from a damaged pipeline associated with a sub-sea well approximately 40 miles southeast of Venice, Louisiana.

Coast Guard officials said the pipeline, which is operated by LLOG Exploration, has been secured.

LLOG Exploration reported that the volume of oil released is estimated to be between 7,950 to 9,350 barrels (or 333,900 and 392,700 gallons).

Officials said two response vessels from Clean Gulf Associates and the Marine Spill Response Corporation reported to the scene. The Coast Guard and contract aircraft are continuing to conduct overflights of the area.

Surface oil is reportedly not expected to reach the shoreline.
