Vienna - The price for oil produced by the Organization of the Petroleum Exporting Countries (OPEC) rose by 20 cents Wednesday, too little to break the 40-dollar mark, according to figures released by OPEC Thursday.

One barrel (159 litres) of OPEC-produced crude stood at 39.54 dollars Wednesday, compared with 39.34 dollars on the previous day.

OPEC calculates a basket price of 12 brands produced by members of the Vienna-based cartel. (dpa)
