Possible oil was observed in satellite imagery. This anomaly is unconfirmed 
as oil. The anomaly was observed in South Timbalier block 37. This anomaly 
was likely related to the sheen reported in NRC report #1206345. The anomaly 
measured 1.5 NM in length and 0.27 NM in width. Winds were 10 kts out 
of the East.
Confidence that the anomaly seen was oil is medium-high. The anomaly exhibited 
sharp contrast with the surrounding area. There were also multiple oil 
facilities nearby along with multiple undersea pipelines. The addition 
of a confirmed sighting of a sheen in the NRC report also adds to the 
confidence of the anomaly seen to have been oil.

The sheen caused by the anomaly may have been caused by a different chemical 
other than crude oil. No point source was confirmed or suspected.
