Oil fell today for the first day in three as traders awaited US monthly jobs data, while Hurricane Earl neared the country's east coast, fuelling concerns of disruptions to refineries and demand during the Labor Day long weekend.
US crude for October dropped 39 cents to $74.63 a barrel, on track for its third weekly drop in four weeks, while ICE Brent declined 42 cents to $76.51.
Prices yesterday settled above $75 for the first time this week, after positive US data on weekly jobs and pending sales of previously owned homes eased concerns the world economy would lapse back into recession. A day earlier, prices rose on strong US and Chinese manufacturing data.
US nonfarm payrolls probably fell for a third straight month in August, a Reuters survey showed, ahead of a monthly report due later on Friday.
Atlantic storms in the past few weeks have veered north, staying away from oil and gas production and refining infrastructure in the Gulf of Mexico.
Still, Hurricane Earl could affect 1.1 million barrels per day of US operable refinery capacity on the Atlantic coast, or about 7 per cent of the nation's total, the US Energy Information Administration said.
"Although Hurricane Earl presents a potential threat to petroleum refineries and seaports, current relatively high inventory levels for most petroleum products should lessen concerns about possible supply outages," the EIA said.
Total US petroleum inventories are at their highest since weekly records began in 1990. In a market where fuel supplies remain ample, a disruption to refineries might prove to be bearish for oil prices as less crude would be processed.
Earl may also curb demand for motor fuel from holidaymakers who stay away from the roads as the US driving season comes to a close this weekend.
Tropical Depression Gaston has weakened further and is now classified as a remnant low-pressure area in the central Atlantic Ocean, the National Hurricane Center said in an advisory.
An oil and gas platform operated by Mariner Energy burst into flames in the Gulf of Mexico on Thursday, but the crew of 13 escaped and there were no signs of an oil spill, the US Coast Guard said.
Rising Asian stock markets today were providing some support for oil prices. Japan's Nikkei edged up 0.6 per cent, buoyed by tech and exporter shares after US data showed an improvement in housing and the job market.
