Crude oil prices were up in early trade in New York on Monday on concerns that Tropical Storm Fay would disrupt oil production in the Gulf of Mexico.
However, as later forecasts showed Fay expected to barely reach hurricane status and to travel up Florida and the East Coast of the United States over the next week, missing key oil production facilities further to the west.
Some companies that had earlier evacuated personnel from platforms in the Gulf have since allowed workers to return.
Prices also fluctuated as investors remained concerned about the effect of the conflict between Georgia and Russia on delivery of oil supplies in the region, but there was news that the Turkish pipeline that was bombed recently is likely to be open again soon after repairs.
