The price of oil produced by the Organization of the Petroleum Exporting Countries (OPEC) fell by nearly three U.S. dollars at the start of the week, the Vienna-based group reported Tuesday. The move comes after a recent push above $70 a barrel (159 liters). The basket price for one barrel of OPEC-produced crude fell to $67.41 , down from $70.27 at the close of last week, according to a report of The German News Agency "DPA". The Group's 12 member countries produce over a third of global crude oil supplies. OPEC's daily price is based on the average price of its 12 main oil varieties.
