The oil price of the Organization of the Petroleum Exporting Countries (OPEC) continued to hover above $70 on Friday, the Vienna-based group reported Monday. The basket price for one barrel (159 liters) of OPEC-produced crude climbed to 70.27 dollars, one cent lower than the previous day, according to a report of the German News Agency "DPA." The cartel's 12 member countries produce over a third of global crude oil supplies.
