Oil futures fell for the second session on track for another weekly decline, following earlier data from the US, the world's largest economy.
As of 06:04 GMT, Brent crude futures shed 0.42% to $51.67 a barrel from the opening of $51.89, Economies.com reported.
Oil futures are swooning for the fourth week in a row as investors assess the damages made by Hurricane Harvey, while noting that Harvey is the worst hurricane to hit Texas in half a century, which led to the stoppage of 2.26 million bpd of refined oil, and closed major pipelines there, in turn stopping petrol pumping to New York ports.
