The price of oil produced by the Organization of the Petroleum Exporting Countries (OPEC) climbed to $69.29 at the end of last week, the Vienna-based group announced Monday. The basket price for one barrel (159 liters) of OPEC-produced crude rose by another 0.75 dollars last Friday, according to a report of the German News Agency "DPA". The Group's 12 member countries produce over a third of the world's oil supply.
