U.S. oil prices rose for the second straight day on Thursday, as positive economic data and robust fuel consumption, offset concerns that slowing growth in other countries could undercut demand.
The U.S. West Texas Intermediate rose 2.7 percent to more than 90 dollars a barrel.
The previous day it rose more than one percent.
The new secretary-general of OPEC blamed policymakers, lawmakers, and insufficient oil and gas sector investments for the high energy prices.
He also said OPEC-plus, during its next meeting in September, could revise output.
Watchers also say the EU ban on Russian oil exports could also dramatically tighten supply and drive up prices.
