   1. USCG MSU Morgan City, LA contacted the NOAA SSC about a sheen from a well located at 29 deg 19.15 min N 091 deg 54.94 min W that produced a silvery sheen of 4 miles by 20 feet in the South Marsh Island Block 239. The wellhead is secure and not releasing any more oil. The sheen is presumed to be moving with the wind in a northerly direction. Quantity not known. USCG is looking for a trajectory to determine if shoreline impacts can be expected.
   2. THREAT: OIL. COMMODITY: CRUDE OIL. MAXIMUM POTENTIAL RELEASE: 1 GALLONS. TAGS: PIPELINE.

   1. On 15FEB12 USCG Morgan City contacted NOAA SSC in regards to a mystery sheen reported at 0745 CST. The sheen is reported as 9mi long and 100 ft wide. It is unknown where in the sheen is in relation to the provided lat/long. There was no initial information related to sheen orientation, product released, source or follow-up information beyond NRC report. During subsequent conversations, the source was determined to be a natural gas pipeline and sheen is produced from condensate. USCG is seeking trajectory to determine shoreline impacts.
