VIENNA, July 12 (UPI) -- Oil supplies from North America are expected to contribute to significant gains in global oil supplies in 2013, the OPEC oil cartel said in its monthly report.
The Organization of Petroleum Exporting Countries, in its monthly oil report, said world oil demand for 2013 is expected to increase by 800,000 barrels per day to 89.5 million bpd. That represents a decline of 100,000 bpd from the growth estimate for the current year, the cartel said.
